Slack Green 블로그

The DMs tab lists your direct messages with people. App DMs, Slackbot and DMs with deleted accounts sit elsewhere. We compared the tab with the full list the Slack API returned.

We uploaded images to a Slack test channel and then switched each image setting off, ran /collapse, and posted from a bot that was not in the channel. Five causes, each reproduced.

Your own name under Direct messages opens a private DM with yourself. We sent it a note, a file, a scheduled message and a reminder, and checked which ones raised a badge.

We added three Slack keywords and had a bot post 12 test messages. Capitals and links matched; plurals, longer words, muted channels and unfollowed threads did not.

Only a workspace owner or admin can hide email addresses in Slack. We switched Email Display to No one, viewed a profile as a coworker, and read the same profile through the API.

Slack admins can cap message editing at 1 minute to 1 week, or turn it off. We set the 1-minute limit and timed when the Edit item and the API stopped working.

Slack의 활성 또는 자리 비움 점과 사용자 지정 상태는 지금 모습만 보이고, 동료나 관리자가 열 수 있는 기록은 없습니다. 유료 플랜 관리자는 마지막 활성 날짜와 로그인 기록을 봅니다. 오늘부터 내 기록을 Slack API로 남기는 법도 담았습니다.

프로필 사진을 누르고 상태 업데이트에서 이모지를 골라 저장하면 Slack 어디서나 이름 옆에 이모지가 나옵니다. 표시 이름에 이모지를 넣는 방법은 2026년 10월 테스트에서 거절됐습니다. 단계, 사용자 지정 이모지, 이모지가 사라지는 이유를 정리했습니다.

자리 비움은 회색 점, 비활성은 28일 동안 Slack을 쓰지 않았을 때의 청구 상태, 비활성화됨은 관리자가 끈 계정입니다. 실제 워크스페이스 관리 페이지에서 각각이 어디에 나오는지 확인했습니다.

Slack에서는 상대 프로필을 열거나, 이름에 마우스를 올리거나, 상태를 확인해도 상대에게 아무것도 가지 않습니다. 본 사람 목록도 없고 관리자도 알 수 없습니다. 상대가 알아채는 것은 DM 입력 표시, 메시지, 반응, 멘션, 허들입니다.

워크스페이스 소유자나 관리자는 비활성화된 Slack 계정을 언제든 다시 활성화할 수 있습니다. 관리자 > 멤버 관리에서 점 세 개를 누르고 계정 활성화를 고릅니다. 단계, Enterprise의 경우, 돌아오는 것과 돌아오지 않는 것을 정리했습니다.

고정 탭이나 메시지 메뉴에서 고정을 해제하고 고정된 항목 제거로 확인합니다. Slack 웹 앱에서 고정, 해제, 수정, 삭제, has:pin 검색, 100개 한도를 시험했습니다.

We uploaded four files to Slack and downloaded them again. The PNG and MP4 came back byte for byte, the JPEG came back re-encoded without its EXIF, and the chat only ever shows a 1024 px preview.

We set a 12-frame animated GIF as a Slack profile photo and downloaded every size Slack made. All of them were still images, frame 1 only.

Slack keeps your recent searches on its servers, so they follow you to every device. We found where to delete them, and the one way the delete button worked for us.

Slack has no Move option for messages. We forwarded a message, a thread and a file to a new channel, deleted the original, and checked what the copy kept.

We deleted our own DM messages, tried to delete the other side's, closed the conversation with /close and reopened it. Here is what each step removed.

We replied in a Slack thread with Also send to channel ticked, removed the channel copy, deleted another, and sent one through the API. Here is what each step did.

We set up a weekday 9:30 standup in a free Slack workspace three ways: a /remind reminder, Workflow Builder, and a short script that posts the questions and collects the thread replies.

We added, renamed, moved, hid and deleted the tabs under a channel name in Slack web on the Free plan, and compared them with the tabs in a DM.

Slack has no bulk leave button. We made 12 test channels and left them with the sidebar menu, the channel browser, /leave and a 30-line script, and timed each way.

As the owner of a free-plan workspace we deleted an app's message, a webhook message and two system messages, in Slack web and with the API, and checked which settings exist.

We wrote drafts in a channel, a thread and a DM in Slack web, then scheduled, sent, archived and left, and checked Drafts & sent and Slack's API after each step.

We marked messages unread in a channel, a DM and a thread in Slack web, read the read state back from the API, and timed what clears it.

We gave a Slack bot one scope, called 44 common Web API methods, and read the needed field of every missing_scope error. Then we added the scopes and called them again. The table shows which scope clears each method.

We uploaded files of 50 MB, exactly 1 GiB and 1 GiB plus one byte to Slack through its upload API. The limit is 1,073,741,824 bytes, and a failed upload can still leave a broken file behind.

Slack's dark mode is under Preferences > Appearance > Color Mode, with Light, Dark and System. We switched modes in Slack web with three test emoji and measured which ones vanish.

The Activity tab collects mentions, reactions, thread replies, reminders and DMs in one feed. We sent a mention and a /remind to a test account and opened every Activity setting in Slack web.

Slack channel names take lowercase letters, numbers, hyphens, underscores and letters from other scripts, up to 80 characters. We sent 45 names to the Slack app and the API and recorded every error.

We archived, unarchived and deleted channels in Slack web and through the API, and recorded what members see, what apps can still do, and which names stay taken.

How to call the Slack Web API from Postman with a bearer token and variables, plus a 16-request collection we ran against a real workspace with newman: 16 requests, 17 assertions, 0 failures, and the five mistakes it checks.

Slack has one spell check switch, under Preferences > Language & region. In our test browser it was on, yet Slack web showed no red underlines: the Grammarly extension had set spellcheck to false on the message box. How to check yours.

Slack은 GPS를 추적하지 않습니다. 접근 로그에는 로그인마다의 IP 주소가 국가, 도시, 통신사와 함께 남고, 소유자와 관리자는 유료 플랜에서만 볼 수 있습니다. 내 로그, 무료 플랜 API, Mac 앱 권한을 직접 확인했습니다.

Help, Troubleshooting, Clear Cache and Restart 순서로 여세요. Slack 4.52.171 테스트에서 캐시 1.5 GB를 약 1초 만에 지웠고, 로그인은 유지됐으며, 3초 안에 다시 시작했습니다. Reset App Data는 모든 곳에서 로그아웃합니다.

We opened a modal with seven input blocks in a test workspace and captured every payload: what Slack checks before your app sees anything, the exact view_submission state.values, response_action errors, dispatch_action, and input blocks in messages.

Slack에서 근무 시간 외임을 알리려면 환경설정에서 근무 시간을 정해 그 밖에는 알림이 멈추게 하고, 자동 상태의 근무 시간 외 항목을 체크하고, 복귀 시간을 적은 상태를 붙이세요. 예시, 동료에게 보이는 것, 매일 상태를 설정하는 스크립트도 정리했습니다.

Slack 상태가 바뀌지 않는 원인은 대개 직접 설정한 상태가 캘린더를 막음, 앱 미동기화, 다른 워크스페이스에서 설정, 자동 상태 꺼짐, 오래된 앱 중 하나입니다. 원인을 가려내는 법과 해결법, 상태와 점의 차이를 정리했습니다.

Slack이 튕기거나 저절로 닫히는 원인은 몇 가지뿐입니다. 오래된 버전, 손상된 캐시, 그래픽 드라이버, 망가진 앱 데이터, Android에서는 System WebView입니다. Mac, Windows, iPhone, Android별 해결 순서와 메시지를 잃지 않고 Slack을 초기화하는 명령을 정리했습니다.

Excel이나 Google 스프레드시트의 셀을 복사해 Slack 메시지에 붙여 넣으면 탭으로 구분된 텍스트가 진짜 표가 됩니다. 한도는 20열, 100행, 10,000자(2026년 10월 6일 시험). 코드 블록, 캔버스 표, Block Kit table block과 시험하며 만난 오류도 정리했습니다.

We uploaded six workspace icons to a test Slack workspace: 100 px, 1024 px, a wide image, a transparent PNG and two oversize files. What Slack accepted, what it stored, and how to remove an icon.

We renamed a free-plan Slack workspace and watched what changed: the sidebar, the search box and the default icon updated in an open tab within seconds, and the URL stayed the same.

The topic sits in the channel header; the description shows in the channel intro and the channel browser. We set both in the Slack UI and with conversations.setTopic and setPurpose and measured the limits.

Seven ways people fake an active Slack status, which ones hold up, and the thing that gives most people away. It isn't the dot.

A normal workday has about five moments where Slack flips you to away. Here's each one, in order, and the cheapest fix for it.

Slack only has two availability states, and neither one is yellow. If you see a yellow dot, it's a theme, an emoji, or a different app.

The Slack Calls API shows a call from your own video or phone service as a card in Slack. We ran calls.add, the call block, participants and calls.end in a test workspace and list every response and error.

Slack has no download or export button for canvases. We checked every menu on a test canvas, used Print canvas for PDF, and turned the API's HTML download into clean Markdown with a script we ran.

Slack forwards one message at a time. We checked the message menu, shift-click and the forward dialog, then tested three ways to move 10 messages at once: a thread, a copied range, and a script that posts links.

Working PowerShell for Slack: Invoke-RestMethod to a webhook, chat.postMessage with a bot token, Block Kit, and a file upload. Every script was run in PowerShell 7.6.6 against a real Slack workspace, with its output.

We renamed a Slack app and its bot user eight times in a test workspace. Which names changed, how fast Slack showed them, the App Home edit that never reached Slack, and the exact validation messages.

We called users.setPhoto 18 times on a test Slack workspace: PNG, JPEG and GIF, crop boxes, a 27 MB file and a broken one. What Slack stored, the errors, and how fast the new photo showed up.

A tested alertmanager.yml for Slack, the messages Prometheus alerts produced, a custom title and text template, and what send_resolved, group_by and color changed. Plus a typo amtool did not catch.

We sent Grafana alerts to Slack through both kinds of contact point, then replaced the default message with a notification template. The messages Slack showed, the delays, the template we used and the errors Grafana logged.

We ran the Jenkins Slack Notification plugin against a real Slack app: the pipeline that worked, the botUser setting that makes slackSend fail with a 404, threads, Block Kit, and the errors for channels the bot cannot see.

We ran 8 Slack node operations in n8n with a bot token, a user token and the OAuth2 credential. What each one can do, the errors you get, and two traps: the OAuth2 callback and the status expiration time zone.

We ran the n8n Slack Trigger against a real Slack app: which URL passes Slack's challenge, why a test event can arrive a minute late, why a channel the bot is not in stays silent, and how the bot can trigger itself.

Slack은 2026년 10월 저장한 메시지를 나중에 탭에서 사이드바의 저장됨(영어 화면에서는 Saved)으로, 리마인더를 해야 할 일 탭으로 옮겼습니다. 저장이 누구에게 보이는지, 리마인더가 무엇을 하는지, 저장한 메시지가 삭제되면 어떻게 되는지 시험했습니다.

볼 수 없습니다. Slack은 관리자에게 검색어 기록을 주지 않습니다. 무료 워크스페이스의 기본 소유자로 확인해 보니 관리자 분석은 워크스페이스 전체 합계뿐이었고, 접근 로그와 분석 API는 거부됐습니다. Enterprise에서는 하루 검색 횟수가 보입니다. 내 최근 검색이 어디에 남는지와 관리자에게 보이는 다른 것도 정리했습니다.

Slack 검색 연산자로 결과를 좁힐 수 있습니다. in:#채널, from:@이름, with:@이름, before:, after:, on:, during:, has::이모지:, is:saved, has:pin, is:thread, "구문", -단어, rep*. 모든 수식어를 예시와 날짜 형식과 함께 정리하고 직접 테스트했습니다.

Slack에서 글머리 기호를 만들려면 줄 맨 앞에 * 나 - 와 공백을 입력하거나 Cmd+Shift+8을 누릅니다. 테스트해 보니 Tab으로 5단계까지 중첩되고, 마크업 모드에서는 목록이 꺼지며, API mrkdwn 텍스트에는 목록이 없지만 markdown 블록에는 있었습니다.

데스크톱에서는 환경설정, 알림, Sounds & appearance에서, 휴대폰에서는 알림, 소리에서 Slack 알림음을 바꿉니다. Slack 안의 파일로 13개 소리를 측정하고, 데스크톱 소리가 계정을 따라오는 이유와 소리 파일을 바꾸면 앱이 깨지는 이유도 정리했습니다.

Mac에서는 로그인 항목에서 Slack을 빼고, Windows에서는 작업 관리자에서 사용 안 함으로 바꿉니다. Mac 단계를 macOS 26.5.2에서 직접 해 보고, Slack 4.52.171의 시작 코드를 읽어 Slack이 다시 켜지는 이유를 설명합니다.

유료 플랜은 워크스페이스가 있는 동안 메시지를 보관합니다. 무료에서는 메시지가 많은 채널에서 정확히 90일 전까지만 보였고 그보다 오래된 것은 나오지 않았습니다. 실제 설정 화면과 선택지도 실었습니다.

Slack은 팔로우하는 스레드의 답글만 알려 줍니다. 스레드 팔로우와 해제, 채널의 Follow every thread를 웹에서 직접 해 보고, 각각의 위치와 동작을 정리했습니다.

We ran the pablovarela/slack Terraform provider against a real Slack workspace: create, update, drift, import, adopt and destroy a channel, plus the exact errors for bad names and missing scopes.

Slack publishes no fixed IP range for the requests it sends to your app. We logged 80 real requests from Slack over 73 minutes: 58 different addresses, all in AWS us-east-1. What that means for a firewall allowlist, and what to check instead.

A complete Slack app on FastAPI with Bolt for Python's adapter: a slash command, a button and an app mention, run behind a tunnel in a real workspace. We timed the acks, pushed one past 3 seconds and broke the signature on purpose.

Apple Shortcuts has no Slack status action, but its Get Contents of URL action can call Slack's API. We built a shortcut that sets a 60-minute status, ran it on macOS 26.5.2, and added a second one that posts a message through a webhook.

Slack's own automatic statuses cover huddles, focus mode and working hours. For anything else you need users.profile.set and a trigger. We built a schedule, a file and an app-launch trigger on macOS and timed each one.

We posted Slack's new carousel and card blocks into a channel and opened alert blocks in a modal, then pushed every field past its limit. Real screenshots, exact errors and the rule that keeps alerts out of messages.

We posted context, header, divider and actions blocks with a bot token and measured the limits, the errors and how Slack's web app draws each one, including the '+ N more' button cut-off.

Slack's Jump to date menu hides in the date divider above messages. We tested it in a 500-message channel and an older channel: which options appear, how far back the calendar goes, and how to do it by API.

Slack's Web API has no single unread-messages call. We tested what conversations.info returns for channels and DMs, counted unreads from last_read, and moved the sidebar badge with conversations.mark.

Slack's custom theme now takes 4 colors. We pasted old 8-color strings, Slack's own Share output and our own themes into Import, and logged which ones Slack accepted.

We switched one Slack app from assistant_view to agent_view and recorded what the user sees, which events arrive, and which status and title calls still work.

Slack's notification schedule now lives under Preferences > Availability > Working hours. We moved it in a test workspace and logged what notified, when, and what stayed paused.

Slack 사용자 그룹은 @핸들 하나로 정해진 사람들에게 알림을 보내는 기능입니다. 유료 플랜에서 만들고 고치고 멘션하는 법과, 프리 플랜 워크스페이스에서는 대신 무엇이 보이는지 시험했습니다.

Slack 입력란에 백틱 세 개를 입력하거나 Cmd+Alt+Shift+C를 누르면 코드 블록이 됩니다. 백틱 뒤 언어 이름이 어떻게 되는지 시험하고, 색이 입혀진 스니펫을 직접 만들고, 봇의 4,000자 넘는 코드 블록이 나뉘어 깨지는 것도 확인했습니다.

Slack 상태에는 Slack이 활동을 보고 정하는 활동 표시 점과, 직접 설정하는 이모지와 텍스트 두 가지가 있습니다. 한도를 시험했고(100자는 저장, 101자는 실패, 이모지가 없으면 💬), 실제 설정 창과 Slack이 다운됐는지 확인하는 법도 담았습니다.

Slack 앱 하나에서 여러 워크스페이스에 로그인하고 Ctrl+Tab이나 Cmd/Ctrl과 숫자로 전환할 수 있습니다. 같은 이메일로 두 워크스페이스를 시험하니 사용자 ID가 둘이었고, 한쪽에서 설정한 상태와 자리 비움은 다른 쪽에 나오지 않았습니다. 추가, 전환, 각각에서 활성을 유지하는 법을 정리했습니다.

채널을 열고 이름을 클릭해 설정 탭의 공개 채널로 변경을 고릅니다. 기본 설정에서 할 수 있는 사람은 워크스페이스 소유자, 조직 소유자, 조직 관리자뿐입니다. 지난 기록과 파일은 모두 워크스페이스에 공개됩니다.

👀는 "보고 있어요, 확인하고 있어요"라는 뜻입니다. Slack에서는 👀 리액션으로 요청을 맡고 ✅로 완료를 알립니다. 힌디어와 스페인어에서의 뜻과, 직장에서 자주 쓰는 리액션 20개의 뜻을 실제 워크스페이스에서 시험한 코드와 함께 정리했습니다.

링크드인의 공고 검색, 저장한 공고, 지원 내역은 회사가 볼 수 없습니다. 구직 환경설정을 확인해 보니 지원할 때 프로필은 공고를 올린 회사에만, 채용 알림 신호는 그 회사 리크루터에게만 갑니다. 드러나는 경로는 모든 회원에게 공개한 구직 중 표시, 알림이 가는 프로필 수정, 업무용 노트북입니다.

Slack 시간대는 프로필 사진, 환경설정, 언어 및 지역 순서로 열어 시간대 목록에서 바꿉니다. 저절로 바뀌는 것을 막으려면 시간대 자동 설정의 체크를 풉니다. 아이폰과 안드로이드에는 자동 스위치만 있습니다. 시간대가 틀리거나 계속 바뀔 때 고치는 법도 정리했습니다.

Slack을 확대하려면 Cmd와 +(Windows는 Ctrl과 +), 축소하려면 Cmd와 -를 누르고, Cmd와 0으로 원래대로 돌아갑니다. 데스크톱 앱은 환경설정, 접근성에 확대/축소 배율도 저장하지만 웹 앱에는 이 설정이 없습니다. 휴대폰에서는 기기 글자 크기를 따릅니다. 헤더 블록으로 글자가 커지는지도 시험했습니다.

We broke a real Slack incoming webhook 25 ways and logged each answer: 403 invalid_token, 404 no_service, no_team, no_active_hooks, 400 invalid_payload, no_text, invalid_blocks and silent 301 redirects.

Slack apps can add two kinds of shortcut: global ones in the composer's shortcut list and message ones in a message's menu. We added one of each, found where Slack puts them, logged both payloads and recorded what users see when the app does not answer.

We posted Slack's datepicker, timepicker and datetimepicker in a message and a modal, picked values and logged every payload. The datetimepicker returns a Unix timestamp; the timepicker returns a bare HH:mm with no zone unless you set one.

A Slack Block Kit button has three looks: no style, primary (green) and danger (red). We posted every kind, clicked each one, logged the block_actions payloads and recorded the errors for colors, disabled buttons and long labels.

To test a Slack API connection, call api.test for the network and auth.test for the token. We ran both with no token, a bot token, a user token, an app-level token and a revoked token, and found that api.test echoes your token back.

Message metadata is a hidden JSON object an app attaches to a message. We posted it with chat.postMessage, read it back, grew it past the limit and logged every event. Bad metadata does not fail the call; Slack drops it and posts the message anyway.

conversations.info returns one channel's name, topic, purpose and flags from its ID. We called it on a public, private, archived and DM channel with a test bot and recorded every field and error.

Slack은 허들 음성과 영상을 녹음하거나 녹화하지 않습니다. 누군가 AI 메모를 켰을 때만 대화록이 저장되고, 허들의 모두에게 알려집니다. 그 밖에 무엇이 남는지, 누가 들을 수 있는지 정리했습니다.

Slack에 기본으로 있는 병가 상태는 자정에 지워지고 알림 일시 중지도 함께 걸 수 있습니다. 2026년 9월 30일 시험해 동료에게 보이는 것, 일찍 지우면 생기는 일, 바로 복사할 병가 상태 13개를 정리했습니다.

@slack/web-api 8.2.0 runs on Node 20 or newer and sends requests with fetch. We posted, paginated, caught a Slack error and a rate limit in TypeScript, and found that the v7 agent option for proxies is silently ignored in v8.

있습니다. Google Chat DM에서는 읽은 사람의 작은 아이콘이 그 사람이 마지막으로 읽은 메시지 옆에 나타납니다. 1:1 DM과 20명 이하 그룹 DM이 대상이고 스페이스는 제외입니다. Google Chat 설정 6개 페이지를 모두 확인했지만 끄는 스위치는 없었습니다.

slack-go/slack v0.29.0 is the Go client most people use for the Slack API. We ran a program that posts, reads back and updates a Block Kit message, a Socket Mode bot that answers a mention, and a loop that hit the rate limit, with the output and error types we got.

Slack 봇 토큰은 앱의 OAuth & Permissions 페이지에 있는 Bot User OAuth Token으로, xoxb-로 시작하고 앱을 설치하면 나타납니다. 받는 순서, SLACK_BOT_TOKEN으로 읽는 법, xoxp 사용자 토큰, xapp 앱 수준 토큰, xoxe 순환, xoxc 세션 토큰과의 차이를 정리했습니다.

업무용이나 학교 Google 계정이라면 관리자가 Google Vault로 Gemini 앱 채팅을 검색, 내보내기, 보관할 수 있고, 삭제한 채팅과 임시 채팅도 포함됩니다. 개인 계정에는 회사가 닿지 못하지만 Google이 채팅을 보관합니다(임시 채팅은 72시간, 그 밖에는 기본 18개월). 계정별로 무엇이 보이는지 정리했습니다.

slack-ruby-client 3.2.0 is the Ruby gem for the Slack Web API. We installed it, posted, read back, reacted and paginated against a real workspace, and recorded the error classes it raised, including the rate-limit error that a rescue of SlackError does not catch.

Slack does not tell anyone when you change your status. An app can find out within a second through the user_status_changed and user_change events. We changed a status 7 ways and timed each event, including statuses that expired.

Ubuntu 화면 잠금을 끄려면 설정, 개인 정보 및 보안, 화면 잠금에서 자동 화면 잠금을 끄고, 화면을 끄기까지의 시간을 안 함으로 바꿉니다. 같은 일을 하는 gsettings 명령어, 절전까지 막는 법, 작업 하나 동안만 잠금을 멈추는 법, KDE Plasma와 Linux Mint에서의 방법을 정리했습니다.

시크릿 모드는 방문 기록을 저장하지 않습니다. Chrome 154로 시험해 보니 시크릿 창의 방문은 기록 데이터베이스에 남지 않았지만, Chrome은 그 사이트를 DNS로 조회했습니다. 회사 Wi-Fi, 회사 VPN, 트래픽을 검사하는 프록시, 모니터링 소프트웨어가 무엇을 보는지, IT 부서가 시크릿 모드를 끄는 방법을 정리했습니다.

Caffeine은 Mac을 깨워 두는 무료 오픈 소스 메뉴 막대 앱입니다. 커피 컵을 클릭하면 Mac이 잠자기에 들어가지 않고, 화면이 어두워지지 않으며, 화면 보호기도 시작되지 않습니다. 진짜 앱을 받는 곳, macOS에 맞는 버전, 모든 설정, 작동 확인 방법, 대체 앱을 정리했습니다.

You cannot type a checkbox into a Slack message. We tried the composer, mrkdwn, a markdown block, a rich_text checklist and a Block Kit checkboxes element, and show which ones render and which ones a person can actually tick.

A Slack canvas is private to the people and channels it is shared with, unless you switch workspace access on. We made a canvas in a public channel, a private channel and a DM, then checked who could open each one.

Shift+Esc marks every Slack channel, DM and Activity item as read after one confirm dialog; Esc clears one conversation. Where the Unreads view (the old All Unreads) is, its shortcut, and what client.counts showed before and after, tested 3 October.

In current Slack, muting a channel also hides it from the sidebar until you turn off one checkbox in Preferences. We muted a test channel, had a bot post and then @mention us in it, and recorded what the sidebar, the badge and Activity showed each time.

Slack channel bookmarks now live in folder tabs above the messages, not in a bookmarks bar. We added, moved and deleted them in a test channel and through the bookmarks API, and found the delete that hides bookmarks the API still lists.

We built a Work Object unfurl for a fake ticket tracker in a free Slack workspace: the manifest setting, the chat.unfurl metadata that rendered the card, the entity_details_requested event behind the flexpane, and every error on the way.

We subscribed a test app to 37 bot events, did 46 things in Slack, and logged every event that reached our HTTP endpoint: which event each action sends, which actions send two or four, which send none, and how long each took.

A Bolt for Python app over HTTP that answers a message, a slash command and a button through the Flask adapter, then the same app as AsyncApp on aiohttp. Console logs from a real run, and the errors a wrong signing secret and an unhandled event gave.

macOS Tahoe에서는 시스템 설정의 배경화면에서 화면 보호기...를 열고 화면 보호기 시작을 안 함으로 바꿉니다. Ventura, Sonoma, Sequoia에서는 잠금 화면, Monterey 이하에서는 데스크탑 및 화면 보호기에 있습니다. 화면을 끄는 타이머와 암호 요구는 별도 설정이고, 핫 코너로도 화면 보호기가 시작됩니다. 터미널 명령도 소개합니다.

Slack 집중 모드는 사이드바에서 켜는 데스크톱 기능입니다. Slack을 회색으로 바꾸고, 숫자 배지를 점으로 바꾸고, 알림음을 멈추며(VIP는 선택), 상태를 30분, 1시간, 2시간 또는 끌 때까지 집중 모드 중으로 바꿉니다. 알림 일시 중지와의 차이, 바뀌지 않는 것도 정리했습니다.

익혀 둘 만한 Slack 키보드 단축키를 Slack 자체 목록에서 Mac과 Windows용으로 정리했습니다. Cmd/Ctrl+K로 이동, Shift+Esc로 모두 읽음, Cmd/Ctrl+Shift+Y로 상태 설정, 서식, 허들, 메시지 한 키 작업까지. Slack에서 Cmd/Ctrl+/를 누르면 전부 볼 수 있습니다.

Slack 프로는 연간 결제 시 사용자 1인당 월 7.25달러, 월간 결제 시 8.75달러이며, 활동한 멤버에게만 요금이 붙습니다. 새 팀은 3개월 동안 월간 요금이 50% 할인됩니다. 무료 대비 추가 기능을 저희 무료 워크스페이스의 요금제 페이지에서 확인하고, 5~50명 기준 비용과 비즈니스+가 나은 경우를 정리했습니다.

We streamed a bot reply into a Slack DM thread with chat.startStream, chat.appendStream and chat.stopStream, timed every call, screenshotted the thread mid-stream, and found how long an idle stream stays open.

Mac이 잠기지 않게 하려면 시스템 설정의 잠금 화면에서 디스플레이 끄기를 안 함이나 더 긴 시간으로 바꾸고, 암호 요구 시간을 늘리세요. 또는 caffeinate -d를 실행합니다. 관리되는 Mac에서 할 수 있는 것과, 그래도 Slack이 자리 비움이 되는 이유도 정리했습니다.

네. Chrome, Edge, Safari나 플레이어 앱에서 재생 중인 동영상은 시스템에 웨이크 락을 요청하므로 화면이 꺼지지 않고 컴퓨터도 잠들지 않습니다. 일시 정지했을 때, 숨겨진 탭에서 음소거일 때, GIF일 때는 통하지 않고, Slack이나 Teams의 활동으로도 치지 않습니다.

We posted a plan block with tasks in all four statuses and standalone task cards from a bot, updated them with chat.update, and probed the limits. pending works only inside a plan, and titles have no length limit we could find.

We opened a Slack modal, pushed views until Slack refused, updated the top view with a current and a stale hash, and answered view_submission with every response_action. Every response and what the user saw.

We posted all four common select menus from a Socket Mode app, picked a value in each, logged the block_actions payloads, and timed an external_select options handler from 0 to 5 seconds. Past 3 seconds Slack silently shows the old results.

We upgraded a Socket Mode Bolt for JS app from 4.6.0 to 5.1.0 and ran it on Node 18, 20, 22 and 26. Two changes failed silently, and a fresh install crashed on Node 20 until we pinned undici 7.

We sent 11 bot messages with different text and blocks combinations to a Slack DM and recorded the notification Slack asked the browser to show for each. Blocks win, text is the fallback, and Slack fills in text when you leave it out.

We called assistant.threads.setStatus and agents.sessions.setStatus on a test app before and after turning on the agent feature, clicked the stop button, and timed how long the status line stays. Every response, the stop event, and what Slack showed.

We caught the payload a slash command sends, answered it as ephemeral, in_channel, plain text and empty, posted to its response_url until it failed, and typed the command inside a thread. Every result is from a test app on 2 October 2026.

We wrote a one-tool MCP server, added it to a Slack app with the mcp_servers manifest field, switched it on in Slackbot and asked for the time. Every request Slackbot sent to the server, the permission prompt, and what Slackbot said when the server was down.

We posted image blocks pointing at our own server with PNG, JPG, GIF, WebP and SVG files, a 404, a redirect, slow responses and files from 2 MB to 42 MB, then used slack_file uploads. What rendered, what failed with downloading image failed, and where the 20 MB line sits.

App incoming webhooks are current. The old 'Incoming WebHooks' custom integration carries a deprecation notice but could still be added on 2 October 2026. We added both, sent channel and username overrides, and posted 60 messages at once to look for a 429.

conversations.members returns the user IDs in a channel, bots included. We ran it on public and private channels with the bot inside and outside each, joined the IDs to names and emails, and hit a cursor that pointed at an empty page.

We added two custom emoji and an alias to a test workspace, then called emoji.list, admin.emoji.add and emoji.add with bot and user tokens on 2 October 2026. emoji.list returned 18 entries while the admin page said 3, and every add call was refused.

We took a new app from 'Activate Public Distribution' greyed out to a working listing form on 2 October 2026. Four checks gate distribution, one HTTP redirect URL is enough to fail the HTTPS check, and the Marketplace asks for 10 active workspaces before you can submit.

We subscribed a Socket Mode app to message.channels, then posted, edited, deleted, replied in a thread, sent a reply to the channel and pasted a link. The raw event for each, three message_changed events nobody typed, and the filter that stopped our bot answering them.

We revoked a user token and a bot token with auth.revoke, then every token at once with the Revoke Tokens button, and logged each response, each event and what kept working. Then we reinstalled and checked the new tokens.

We called users.info and users.profile.get for a person, a bot and Slackbot, changed the person's display name in between, and logged which fields moved. Code, output, the email scope test and every user_not_found case we hit.

Slack paginates list methods with a cursor: pass response_metadata.next_cursor back as cursor until it is empty. We paged 27 real messages on 2 October 2026 and broke the cursor five ways to see which ones fail.

A Slack app created today cannot use the RTM API. We called rtm.connect and rtm.start with every token a new app gets on 2 October 2026, tried to request the rtm:stream scope, and ran the same bot over Socket Mode.

icon_emoji, icon_url and username only work with the chat:write.customize scope, and Slack ignores them silently without it. We tested every case on 2 October 2026, plus webhooks and the app icon upload limits.

We sent chat.postMessage with as_user=true, as_user=false and no as_user, with a bot token and a user token. as_user=true changed nothing, as_user=false was rejected, and only the user token posted under the person's name.

A Slack bot has three IDs: a user ID (U...), a bot ID (B...) and an app ID (A...). We called auth.test with a bot, user and app-level token on 2 October 2026 and show where each ID turns up.

We ran Slack's Add to Slack flow against a 34-line Python callback on localhost, then broke each step: a reused code, a typo, a wrong secret, a wrong redirect_uri, a cancelled consent screen and a code we held for 11 minutes.

With token rotation on, Slack access tokens start with xoxe. and expire after 12 hours. We turned it on for a test app on 2 October 2026, refreshed the token six times, and logged which old tokens kept working.

회사가 노트북 카메라로 나를 볼 수 있는 것은 화상 통화 중과, 카메라를 켜는 프로그램을 통할 때뿐입니다. Windows 11과 macOS에서 카메라가 켜졌는지 알아보는 법, 웹캠 사진을 찍는 모니터링 도구, 법이 허용하는 범위를 정리했습니다.

conversations.list returns every public channel but only the private channels your bot is in. We ran it with a bot token and a user token on 2 October 2026 and pasted what each one returned.

We posted rich_text blocks with every element type, lists nested 9 levels deep, quotes and code, then broke them on purpose. The JSON we sent, screenshots of how Slack web drew it, and the exact invalid_blocks errors.

Slack 무료 플랜에서는 최근 90일의 메시지와 파일만 보이고, 1년이 지난 데이터는 삭제되며, 앱은 10개까지, 허들과 Slack Connect는 1:1만 됩니다. 고객지원센터에 나온 모든 제한, 90일째에 일어나는 일, 유료로 바꿀 만한 때를 정리했습니다.

We added people and bots to public and private channels with conversations.invite and conversations.join, using a bot token and a user token. Every response we got, including already_in_channel, cant_invite_self, cant_invite and the force flag.

We called users.list with a bot token in a one-person workspace and got 14 members back: Slackbot, 1 person, 4 live bots and 8 deleted ones. The script, the curl call, cursor paging to the end, and what users:read.email changes.

Slack 메시지에서 보내지 않고 줄을 바꾸려면 Shift+Enter를 누르세요. Enter로 줄을 바꾸고 싶다면 환경설정의 고급에서 메시지 작성 시 Enter 키 동작을 "새 줄 시작"으로 바꾸고, Cmd+Enter나 Ctrl+Enter로 보내세요. 모바일, 목록, 코드 블록, API 줄바꿈도 정리했습니다.

Slack 아이콘의 빨간 점은 어딘가에 읽지 않은 활동이 있다는 뜻이고, 빨간 숫자는 DM, 멘션, 키워드, 팔로우한 스레드 답글을 뜻합니다. Shift+Esc로 모두 읽음 처리하고 스레드, 활동, 해야 할 일, 다른 워크스페이스를 확인한 뒤 캐시를 지우거나 운영체제 배지를 초기화하세요.

We pointed a slash command at a local server and broke it on purpose: HTTP 500, 401 and 302, a wrong path, a dead tunnel, a stopped server and Socket Mode with no process. Each one gave dispatch_failed. A slow reply gave operation_timeout instead.

Slack 앱이 열리지 않을 때는 대개 창 없이 이미 실행 중이거나, 뽑아 둔 모니터에 창이 있습니다. Slack 프로세스를 모두 끝내고 다시 열고, 안 되면 앱 데이터 초기화, 재설치, 로그인 링크 확인을 하세요. Windows 11과 Mac 단계입니다.

Slack 메시지 text의 한도는 40,000자이고, 개발자 문서는 4,000자 미만을 권장합니다. API로 시험해 보니 긴 글은 잘리지 않고 4,000자씩 메시지로 나뉘어 올라갔습니다. Block Kit 섹션은 3,000자, 헤더는 150자까지입니다. 긴 메시지에서 일어나는 일, 다른 글자 수 한도, 긴 글 나누는 법을 정리했습니다.

We clicked a button, a static_select and a datepicker in Slack on 1 October 2026 and logged the block_actions payloads our app received. Then we measured response_url: 5 posts, then used_url; it worked at 29:50 and was dead at 30:10.

We posted a web page, a YouTube video and an image with every combination of unfurl_links and unfurl_media on 1 October 2026, then built a custom preview with link_shared and chat.unfurl. The flags do not split the way the names suggest.

We scheduled five messages for 4:40 PM on 1 October 2026, then archived, left and deleted their channels and deleted a thread parent before the send time. Two sent, three never did, and Slack gave no notice about the three.

We broke a Slack bot nine ways on 1 October 2026, in Socket Mode and over HTTP, and wrote down what the person in Slack saw and what the app received each time. The table of causes, symptoms and fixes comes from those runs.

A Slack bot can DM a user by passing the user ID as the channel in chat.postMessage, or by opening the DM with conversations.open first. We ran both, recorded where each message landed, and reproduced messages_tab_disabled and 'Sending messages to this app has been turned off'.

We made a Slack Events API endpoint fail on purpose and logged every redelivery with its X-Slack-Retry-Num and X-Slack-Retry-Reason headers. Slack retried 3 times, at about 0 s, 1 minute and 6 minutes. Measured timing, what X-Slack-No-Retry does, and a handler that stops the retries.

Slack signs every request with your app's signing secret: HMAC-SHA256 of v0:timestamp:raw body. We verified a real slash command and a real event on 1 October 2026, then broke it the four ways apps break it.

A Slack message link is /archives/<channel>/p<ts without the dot>. We copied links in Slack web and called chat.getPermalink on 1 October 2026 to compare the formats for channel messages and thread replies, then turned links back into a channel and ts.

We created a channel canvas with the Slack API, wrote markdown into it, found sections and edited them, then read it back. The free-plan errors, the markdown that rendered and the mention syntax that did not.

We called reactions.add with standard, aliased, skin-tone and custom emoji names in a test workspace, then kept adding reactions until Slack refused. Every response, the reaction_added payload, and the per-user limit we hit.

Slack verifies an Events API Request URL by POSTing a url_verification challenge. We ran a 16-line Flask handler behind a tunnel and recorded the request, the Verified tick, and the exact error Slack shows for a wrong body, an HTTP error and a slow reply.

We built a Slack App Home tab with views.publish in a test workspace and recorded the app_home_opened payload, every error a bad view returned, and what users see when the Messages tab is off or read-only.

We added localhost, 127.0.0.1, https, custom-scheme and tunnel redirect URLs to a Slack app on 1 October 2026, then ran the OAuth flow against a local server. What was accepted, how Slack matches the URL, and the PKCE rules.

A Slack app manifest we used to create a working app on 1 October 2026, in YAML and JSON, plus the validation errors from broken versions and real output from apps.manifest.validate, export, create and update.

chat.delete removes a message by channel and ts. We deleted bot messages, a person's messages, a thread parent and an already deleted message with bot and user tokens, and list every response, including cant_delete_message and the tombstone a thread parent leaves.

We opened a Slack modal with views.open after delays from 0 to 5 seconds, 28 times, on 1 October 2026. The success rate per delay, the exact errors, and the Bolt code that avoids expired_trigger_id.

users.lookupByEmail turns an email address into a Slack user ID. It needs the users:read.email scope. We ran it with the right and wrong emails, upper case, spaces and a token without the scope, in curl and Python, and list every response.

We sent Block Kit messages just under and just over each limit through chat.postMessage and an incoming webhook on 1 October 2026. The last value that worked, the first that failed, and the exact error text for each.

We called auth.test with no token, a broken token, a revoked token and tokens from an uninstalled and a deleted app, and wrote down every response. invalid_auth, not_authed, account_inactive and token_revoked each point to a different fix.

search.messages works only with a user token that has search:read. We ran it against our own test workspace: the response shape, the bot token error, 10 search modifiers with their counts, paging limits that fail silently, how long new messages take to show up, and the newer assistant.search.context.

To reply in a Slack thread, pass the parent message's ts as thread_ts. We tested it with a bot token, a webhook and Socket Mode events on 1 October 2026, including the values that silently post to the channel instead.

We sent ephemeral messages with chat.postEphemeral, in a channel and in a thread, then tried chat.update and chat.delete on them, replaced and deleted them through response_url, and checked what was left after a reload. Every response is from the real run.

We called chat.update with a bot token and a user token on 1 October 2026: the response, every error we hit, the 4,000-character cap, and what an edit shows and notifies in Slack.

A 13-line Bolt for Python app that answers in Slack over Socket Mode, run against a real workspace, plus the exact errors from the wrong token, a missing connections:write scope, and two copies running at once.

게스트는 내 Slack 워크스페이스에 들어오고, 다중 채널 게스트의 비용은 내 회사가 냅니다. Slack Connect는 두 워크스페이스를 연결하고, 각 회사가 자기 인원만큼 냅니다. 비용, 제한, 권한, 무엇을 고를지.

LinkedIn에서 사진에 붙는 꽉 찬 초록 점은 지금 LinkedIn에서 활동 중이라는 뜻입니다. 속이 빈 초록 원은 지금은 없지만 모바일 앱으로 바로 알림이 간다는 뜻입니다. 설정 및 개인정보, 공개 범위, Manage active status에서 끌 수 있지만, No one으로 하면 다른 사람 상태도 안 보입니다.

Slack에 Google 캘린더 앱을 설치하고 기본 캘린더를 연결해 상태 동기화를 켜면, 다른 참석자가 있는 수락한 일정에서 "회의 중", OOO나 PTO 일정에서 "부재중"이 붙습니다. 방법, 규칙, Outlook, 동기화가 안 되는 이유.

Outlook에서 초록은 대화 가능, 빨강은 다른 용무 중, 모임 중, 방해 금지, 노랑은 자리 비움, 회색은 오프라인이나 상태 알 수 없음, 보라는 부재중입니다. 점은 Outlook이 아니라 Microsoft Teams 상태에서 옵니다. 색을 정하는 것, 회색이 되는 이유, 숨길 수 있는지, 일정 표시 방법 색과의 차이.

Windows용 Caffeine은 59초마다 F15 키 이벤트를 보내 컴퓨터를 깨워 두는 Zhorn Software의 무료 트레이 앱입니다. 2026년 10월 3일 caffeine.zip을 내려받아 exe 두 개의 크기, SHA-256, 서명, VirusTotal 결과, 트레이 아이콘을 확인했습니다. 쓸 만한 스위치와 PowerToys Awake 비교도 정리했습니다.

Mac에서 Slack 알림이 멈추는 원인은 대개 macOS 쪽에 있습니다. Slack 알림 권한, 집중 모드나 그 일정, 화면을 공유하는 동안 모든 배너를 숨기는 설정입니다. Mac에서 확인할 순서와 Slack 설정, 소리, 초기화 방법을 정리했습니다.

We called chat.scheduleMessage with a bot token for times from 10 seconds to 121 days ahead, listed and deleted the results, and watched which messages still arrived. The limits, the exact errors, and a delete that returned ok but did not stop the post.

Slack invite links expire after 30 days and have no longer option. We made links in a test workspace, deactivated them, and found a signed-out check that tells a live link from a dead one.

Slack's Set up mobile overrides checkbox lets your phone get a different notification level than your computer. We ticked it in every combination and read back the saved settings after each click.

Slack has no superscript format. We sent ^2^, ², x^2 and Unicode characters from the message box, the API and a Block Kit markdown block: only Unicode rendered raised. Copy-ready characters, and how Slack search treats them.

Slack에 커스텀 이모지를 추가하려면 입력창의 스마일 아이콘에서 "이모지 추가"를 열고, 이미지를 올리고 이름을 붙여 저장합니다. 저희 테스트에서는 정지 이미지는 모두 128 x 128로 줄어든 뒤 받아들여졌고, 거부된 것은 큰 GIF뿐이었습니다.

Call conversations.history, follow next_cursor, then fetch each thread with conversations.replies. We read 40 seeded messages and 6 replies from a test channel and show the script, its output, and what limit, oldest and latest did.

Discord 방해 금지는 상태를 빨간색으로 바꾸고, 멘션, DM, 통화 벨소리를 포함한 데스크톱 팝업과 소리를 끕니다. 메시지와 통화는 계속 오고, 읽지 않음 배지도 계속 쌓입니다. Discord에 따르면 모바일 푸시 알림도 옵니다. 타이머로 켜는 법, 오프라인 표시·자리 비움과의 차이, 저절로 켜지는 이유를 정리했습니다.

Three short Python scripts that post to Slack, run against a real workspace with their output: an incoming webhook with requests, chat_postMessage with a bot token, and a thread reply. Plus the errors we triggered and what an 80-message burst did.

Discord에는 한 사람이나 한 서버에만 오프라인으로 보이는 방법이 없습니다. 오프라인 표시는 모두에게서 숨깁니다. 차단, 무시, 친구 삭제, 서버별 활동 설정이 각각 무엇을 숨기는지 Discord 고객지원 문서를 바탕으로 정리했습니다.

회사 노트북이나 회사 네트워크라면 대개 볼 수 있습니다. 네트워크에는 모든 사이트 이름이, 검사용 프록시나 모니터링 프로그램에는 페이지 내용까지 보이고, 시크릿 모드가 숨기는 것은 기기의 기록뿐입니다. 층마다 무엇이 보이는지와 내 노트북을 확인하는 법을 정리했습니다.

회사의 ChatGPT Enterprise, Claude, Microsoft 365 Copilot 계정이라면 회사는 대개 대화를 읽을 수 있습니다. ChatGPT Business에서는 기본 설정으로는 읽을 수 없습니다. 개인 계정이라면 기록을 열 수 없지만, 회사 노트북은 입력하는 내용을 기록할 수 있습니다.

The official Slack MCP server lives at https://mcp.slack.com/mcp and needs a user token from an app with MCP turned on. We built one, connected Claude Code and Codex CLI, sent a message and searched for it, and copied every response.

Discord 상태 색은 다섯 가지입니다. 초록은 온라인, 노란 초승달은 자리 비움, 가로줄이 있는 빨간 원은 방해 금지, 보라는 방송 중, 회색은 오프라인 또는 오프라인 표시입니다. 초록 휴대폰 모양은 모바일 앱에서만 온라인이라는 뜻입니다. 아이콘별 의미와 이름 옆의 음소거, 헤드셋 음소거, LIVE, 왕관, 보석 아이콘까지 정리했습니다.

Discord에서 오프라인 표시와 오프라인은 똑같이 회색으로 보입니다. 오프라인은 어느 기기에서도 로그인하지 않은 상태입니다. 오프라인 표시는 메시지 보내기까지 평소처럼 Discord를 쓰면서 모두에게 오프라인으로 보이는 상태입니다. 그래도 들키는 행동과 오프라인 표시로 할 수 없는 것을 정리했습니다.

Slack messages can now carry real charts. We posted line, bar, area and pie charts and a sortable data table to a test workspace with a bot token, a webhook and a user token, and logged every limit Slack enforced.

Slack Green을 쓰는 동안 동료, 워크스페이스 관리자, 회사 IT가 무엇을 볼 수 있는지 실제 Slack 접속 기록으로 확인했습니다. 6시간마다 저희 서버 IP에서 웹 세션이 기록됩니다.

A Slack member ID is the U... code that identifies a person. Copy it from their profile under the three-dot menu, or look it up with users.info and users.list. Tested in two workspaces, with the ID formats we found.

Slack answers too many calls with HTTP 429 and a Retry-After header. We burst chat.postMessage, conversations.history and an incoming webhook from an internal app and logged every response: where the 429s started, the bodies, and a retry loop that never hit one.

files.upload now returns method_deprecated. Use files.getUploadURLExternal, POST the bytes, then files.completeUploadExternal, or files_upload_v2 in the SDK. Tested with curl and Python, including two silent failures.

channel_not_found means Slack cannot see the channel with the token you used: a wrong ID, a name that does not exist, a private channel the bot is not in, or a channel in another workspace. Each case tested on a real bot.

not_in_channel means the bot is not a member of the channel you posted or read from. Public channel: conversations.join or chat:write.public. Private channel: /invite the app. Every response here came from a real app.

Slack returns missing_scope when the token lacks a scope the method needs. The response names it in 'needed'. Add that scope, reinstall the app, and call again. Tested on a real app.

Open the emoji picker, click Skin Tone at the bottom right and pick one of six hands. We tested where the default applies on 29 September 2026: the picker, autocomplete and reactions use it, but a fully typed :thumbsup: does not.

Slack has no text color option in messages or canvases, and the API rejects a color style. We tested every route on 29 September 2026. A hex code gets a color swatch, inline code is red, and app messages can carry a colored bar.

Slack has no spoiler formatting. We sent Discord's ||text||, Reddit's >!text!< and //text// in Slack on 29 September 2026: all three show in plain sight. A thread reply is the workaround that hides the answer.

You can type a URL into a Slack status, but it shows as plain text that nobody can click. We tried a pasted URL, Markdown and Slack's own link syntax on 29 September 2026; none became a link.

Click the channel name and read the last line of the About tab: Channel ID, with a copy button. We also ran the API calls that fail when you pass a channel name instead of the ID, and the fix.

The headphones icon in Slack means huddles: the button that starts one, a live huddle next to a channel, the bar you are in. We started a huddle alone to show every spot, and checked whether you can huddle in your own DM.

We typed every common markdown shortcut into a Slack canvas. Headings, lists, checklists, quotes and code convert as you type; a single *star* makes bold, not italic; links, dashes for a divider and ==highlight== stay as plain text.

A Slack huddle has two backgrounds: the one behind you on camera, and the theme behind the whole huddle window. Where each one is, what you can pick, and why many people see no upload button.

할 수 있지만 한계가 있습니다. 소유자와 관리자는 활성 일수, 게시한 메시지 수, 로그인, 요금제에 따라 DM 내보내기를 봅니다. 앱은 초록 점을 기록할 수 있습니다. Slack은 키 입력, 마우스 경로, 스크린숏을 기록하지 않습니다.

Zoom의 초록색 동그라미는 데스크톱에서 대화 가능, 초록색 휴대폰 모양은 모바일에서만 대화 가능, 회색 시계는 자리 비움, 빨간 아이콘은 바쁨, 방해 금지, 회의 중, 통화 중입니다. Zoom 상태 아이콘 전체와 바뀌는 계기.

Set a reminder on a Slack message from its three-dot menu, then watch where it goes. We tested it on 29 September and 8 October 2026: the message waits in To-dos (formerly Later) and fires as a card in Activity, with no Slackbot DM.

동료 모두의 점이 한꺼번에 회색이 됐다면 문제는 거의 언제나 팀이 아니라 내 Slack 앱입니다. 왜 생기는지, 어떻게 알아보는지, 해 볼 순서대로 정리한 해결책.

관리자 권한 없이 PowerShell로 Windows가 절전되지 않게 하는 법. SetThreadExecutionState로 절전과 화면 꺼짐을 막거나, 1분마다 F15를 눌러 유휴 타이머를 초기화합니다. 실행과 중지 방법, powercfg 한 줄, Teams와 Slack에 주는 효과.

Slack's own reminder bot is /remind, which also reminds whole channels. If you are building one, reminders.add still works with a user token, but one-time reminders it creates land in the To-dos tab where reminders.list cannot see them.

슬랙 허들 문제는 대부분 마이크나 카메라 권한 때문입니다. Microphone permission denied와 Unknown Device 오류를 재현하고, 슬랙 자체 테스트를 돌려 증상별 해결 방법을 정리했습니다.

읽지 않은 메시지가 없는데 Slack에 배지가 뜬다면 스레드, 다른 워크스페이스, 활동, 해야 할 일, 오래된 캐시 중 하나가 원인입니다. Shift+Esc로 모두 읽음 처리하고, 스레드를 열고, 남으면 캐시를 지우세요.

Most broken Slack reminders are misread commands, or reminders that did fire but went to Activity and Later instead of a Slackbot DM. Each failure below was reproduced in Slack on 29 September 2026.

Slack 관리자는 앱에서 내 DM을 열 수 없습니다. 워크스페이스 소유자로 확인해 보니 표준 내보내기에는 DM과 비공개 채널이 빠지고, 분석에는 DM에서 읽힌 비율만 나왔습니다. 비즈니스+와 Enterprise의 소유자는 신청하면 DM을 내보낼 수 있습니다.

One-time Slack reminders can only be moved to a new time from the To-dos tab, called Later until October 2026. Recurring and channel reminders cannot be edited at all: delete them from /remind list and set them again.

A lot of pages say Slack waits 30 minutes before showing you away. Slack's own docs say 10. What the online dot really tracks, and how far to trust it.

To make an emoji from a video, cut 1 to 2 seconds, crop it to a square, scale it to 128 x 128 and save it as a GIF under 128 KB for Slack or 256 KB for Discord. One tested ffmpeg command, the frame rate and color settings that decide the file size, and a free browser tool that shrinks the GIF for you.

To make a custom Discord emoji, crop an image to a square, keep it under 256 KB, name it with letters, numbers and underscores, and upload it with Add Emoji in the emoji picker or Server Settings, Emoji. How to make one from a photo, a GIF or text for free, add animation, and use it in other servers.

Slack's Block Kit Builder at app.slack.com/block-kit-builder lets you pick a template, add blocks, preview the message on Desktop or Mobile, and copy the JSON payload for a webhook or chat.postMessage. A walk through the current builder, a working deploy message, and the steps to send it.

Yes. Slack messages, including DMs, can be requested in a lawsuit or an investigation. Most requests go to the company that owns the workspace, which exports them. Slack itself gives out message content only with a search warrant and tells the company first. Slack's own policy, its disclosure numbers, legal holds, and what deleted messages mean.

A wireless mouse with a jiggler is a normal mouse with a jiggle mode in its firmware: hold the DPI button for about 3 seconds and the cursor moves on its own. Two models in the top results, how they compare with a USB dongle and a mechanical mover, and what they do for Teams and Slack.

PowerToys shows 'This setting is managed by your organization' when your IT team set a group policy for Awake. A value of 0 forces Awake off and greys out the toggle; 1 forces it on. How to see which policy applies with one reg query, why Awake exits when started from the command line, and what you can still do.

Switching between Online, Idle and Do Not Disturb sends no notification. But friends on the Discord mobile app can get a push when you come online, set a new custom status, or start a game, and you cannot stop Discord from sending it. They can turn it off on their side; you can go Invisible.

Clockify tracks idle time only if you turn on idle detection, and only you see it: after the minutes you set with no mouse or keyboard input, it asks whether to keep or discard that time. Admins can see screenshots and GPS on paid plans, not idle time or the auto tracker.

To mention someone in a Slack incoming webhook, put their member ID in angle brackets: <@U0123ABCD>. A plain @name stays text. @here is <!here>, @channel is <!channel>, and a user group is <!subteam^S0123ABCD>. Where to find the IDs, a lookup-by-email script, and what we measured.

If your Discord status will not change, you are usually clicking the wrong spot: the status list now sits behind the current status line in your profile panel. Other causes are a manual Idle that never ends, an app that missed the update, a custom status timer, and Discord outages. Fixes for desktop, browser and mobile.

Any AI image tool can draw a Slack emoji. Prompts that read at 22 pixels, the AI emoji tools in the top results, and what Slack really does with a large AI image, tested.

Working across time zones works when the team writes things down, keeps a short overlap window for live talk, says the zone with every time, and lets tools deliver messages in each person's working hours. Ten habits, a follow-the-sun handoff note, the Slack settings that help, and a script that shows your team's local times.

Use 🌴 :palm_tree: for OOO, ✈️ :airplane: for travel and 🗓️ for planned PTO. Slack has no :ooo: emoji, so download six free OOO, PTO and BACK MON emoji, tested in a real Slack status.

Send a Slack message with one curl command: POST a JSON body with a text field to your incoming webhook URL, and Slack answers ok. Tested examples for curl, jq, Block Kit, Python with retries and Node.js, how to escape quotes and new lines, and what 400 invalid_payload and 429 mean in code.

Webex shows In a meeting while a Webex meeting is still open on any of your devices, and In a calendar meeting while an event is on your calendar. Leave the meeting everywhere, check your calendar, or turn off Show when in a calendar meeting. Plus the fixes when Webex status does not show in Outlook.

RingCentral usually shows In a meeting when you are not in one because Calendar presence is on: it shows In a meeting for every event on a connected calendar, whether you join or not. How to turn it off, the other four causes (Teams presence sync, a meeting that never ended, another RingCentral app, old events), and what each presence icon means.

Slack has no API to start, join or record a huddle. Apps can read whether a user is in one from huddle_state on the user profile, see which channel from huddle_state_channel_id, and get the user_huddle_changed event when it changes. Code for both, plus audit log events on Enterprise.

Logitech does not make a mouse jiggler, and Logi Options+ has no keep-awake setting. What works with a Logitech mouse: a mover platform wide enough for an MX Master, a USB jiggler next to your receiver, a G HUB Lua script for G-series mice, or a keep-awake app. What each one does for Slack and Teams.

Discord on Steam Deck does not show what you are playing by itself. Install Discord as a Flatpak, add it to Steam, then add the Discord Status plugin through Decky Loader. Keep Discord running and friends see 'Playing [game] on Steam Deck'. Setup, fixes, and the alternatives.

Create a Slack app at api.slack.com/apps, turn on Incoming Webhooks, click Add New Webhook to Workspace and pick a channel. Slack gives you a hooks.slack.com URL that posts to that channel. Private channels, DMs, several channels, the Workflow Builder alternative, and the errors you may see.

Slack shows an uploaded .md file as raw text, with the # and ** characters visible. To read it formatted, paste the rendered text into a canvas, create the canvas from markdown with the API, or send it in a markdown block. HTML files and Mermaid diagrams do not render either; the workarounds are below.

Block Kit text objects with type mrkdwn use Slack's own syntax: *bold*, _italic_, <url|text> links and <@U123> mentions. The markdown block takes standard markdown, with lists, headings and tables, up to 12,000 characters per payload. Syntax tables, JSON you can paste, bullet lists, links and mentions.

In 8x8 Work, a green check means Available, solid red means Busy, red with a phone means On Call, red with a bar means Do Not Disturb, an amber clock means Away, and a grey X means Offline or Invisible. What each status does to your calls, which ones change by themselves, and the Contact Center agent statuses.

An out of office message when you leave a company says you have left, since when, and who handles your work now: 'I left Acme on 30 September. For billing, please contact Dana Kim.' 14 templates for the auto-reply, your last-day Slack or Teams status and the farewell post, and how to set each one.

A holiday Slack profile picture works best as your own photo with a seasonal touch: a Santa hat, a candy-cane frame, a Halloween hat.
