How to copy text from remote server to clipboard?

Thu, 19 Mar 2026 13:06:02 +0330

First define this bash function:

# Add to remote ~/.bashrc
clip() {
 # Read from stdin, encode to base64 (disable wrapping with -w 0), 
 # and wrap in the OSC 52 escape sequence.
 local b64
 b64=$(cat | base64 -w 0)
 printf "\033]52;c;%s\a" "$b64"
}

or for fish:

function clip
 # Read from stdin, encode to base64, and save to a local variable
 set -l b64 (cat | base64 -w 0)
 # Output the OSC 52 sequence directly to the terminal
 printf "\033]52;c;%s\a" "$b64"
end

Then you can easily run:

cat file.txt | clip

Note that if you use tmux you should allow clipboard:

set-clipboard on

How to Allocate swap in GNU/Linux?

NixOS Python Packages that Depend on C shared libraries

Wed, 18 Feb 2026 15:48:27 +0330

If you see this error:

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

 https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

 * The Python version is: Python 3.13 from ""
 * The NumPy version is: "2.4.2"

and make sure that they are the versions you expect.

Please carefully study the information and documentation linked above.
This is unlikely to be a NumPy issue but will be caused by a bad install
or environment on your machine.

Original error was: libstdc++.so.6: cannot open shared object file: No such file or directory

Install appimage-run and then run this:

export LD_LIBRARY_PATH="/nix/store/vfsghxsap24k8gcg4z4dbp42av6hdbr0-appimage-run-fhsenv-rootfs/usr/lib64"

Use Tor project's oniux instead (maybe in the future, it hasn't worked for me yet)

Bluetooth Audio Troubleshooting in Linux

Fri, 02 Jan 2026 01:41:43 +0330

Assuming you use pipewire:

journalctl --user -f -u pipewire -u wireplumber
pw-top (look for error column)
btmgmt --index 0 info
btmon
journalctl -u bluetooth
From here:
- pw-metadata -n settings 0 clock.force-rate <samplerate>
- pw-metadata -n settings 0 clock.force-quantum <buffersize>
- Confirm the actuall sample rate and buffer size? pw-metadata -n settings

How To Run Any CLI Program Over a TCP Socket, or How To Run a CTF?

Fri, 14 Nov 2025 19:08:32 +0330

If you want to run a CTF sometimes you'd like to give telnet access to a program to the participants. How do people do that?

Well here's the gist of it. Run the following docker build file using docker compose build and you'll be done. The binary file chal, and flag.txt should be in the same directory.

FROM debian:latest
ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update -y && \
 apt-get install -y socat && \
 apt-get clean && \
 rm -rf /var/lib/apt/lists/*

RUN useradd -u 1001 -d /home/user -s /bin/bash user

WORKDIR /home/user

COPY chall /home/user/
COPY flag.txt /home/user/

RUN chmod 111 /home/user/chall
RUN chmod 444 /home/user/flag.txt
RUN chmod -R 555 /home/user

EXPOSE 1337
ENTRYPOINT ["socat", "TCP-LISTEN:1337,reuseaddr,fork,nodelay,su=user", "EXEC:'timeout 180 ./chall'"]

You could change ./chall part to yes for example and see that any client that connects to that socket over telnet sees a lot of "y"s :)

How to apply SOCKS5 proxy for docker pull?

Sun, 26 Oct 2025 17:06:24 +0330

First open /etc/docker/config.json then add the following data in it:

 {
 "proxies":
 {
 "default":
 {
 "httpProxy": "socks5h://127.0.0.1:30808",
 "httpsProxy": "socks5h://127.0.0.1:30808",
 "noProxy": "localhost,127.0.0.1"
 }
 }
 }

After restarting your docker service using systemctl restart docker the change will be done.

For docker build the story is different and you can use the following command to apply it per command, docker run example is included too:

docker build --build-arg HTTP_PROXY="http://127.0.0.1:30808" .
docker run --env HTTP_PROXY="http://127.0.0.1:30808" redis

If these methods don't work, you can also do this:

mkdir -p /etc/systemd/system/docker.service.d
cat > /etc/systemd/system/docker.service.d/proxy.conf <<EOF
[Service]
Environment="HTTP_PROXY=socks5://127.0.0.1:30808"
Environment="HTTPS_PROXY=socks5://127.0.0.1:30808"
EOF
systemctl daemon-reload
systemctl restart docker docker.service

How to fix SVGs for dark mode?

Tue, 16 Sep 2025 18:30:06 +0330

This one's easy. I'm assuming that SVG is imported using an img tag.

Open your SVG file in beloved VIM or Emacs's evil mode. Do this:

:%s/stroke="rgb(0,0,0)"/stroke="currentColor"/
:%s/fill="rgb(0,0,0)"/fill="currentColor"/

Or you could just use sed. Anyway, then add

style="background: #ffffff; background-color: light-dark(#ffffff, var(--ge-dark-color, #000000)); color-scheme: light dark;"

to the top of your SVG file in your svg tag, here's a diff from my own blog's commits:

-<svg version="1.2" width="44.92mm" height="130.98mm" viewBox="0 0 4492 13098" preserveAspectRatio="xMidYMid" fill-rule="evenodd" stroke-width="28.222" stroke-linejoin="round" xmlns="http://www.w3.org/2000/svg" xmlns:ooo="http://xml.openoffice.org/svg/export" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:presentation="http://sun.com/xmlns/staroffice/presentation" xmlns:smil="http://www.w3.org/2001/SMIL20/" xmlns:anim="urn:oasis:names:tc:opendocument:xmlns:animation:1.0" xmlns:svg="urn:oasis:names:tc:opendocument:xmlns:svg-compatible:1.0" xml:space="preserve">

How to tunnel all your outgoing traffic using WireGuard, but keep your connection to your VPS

Add this to your wireguard config:

How to migrate torrent files from one qBittorrent cilent to another?

Sat, 16 Aug 2025 11:13:49 +0330

I have had this problem where I reinstalled my OS and qBittorrent forgot all about my downloaded torrents. I was facing a brand-new, blank page in qBIttorrent. I could not seed the files I already had. Here's how I solved it.

For me, all files downloaded from torrent go inside a single directory, without any change in their name (except some that have naming conflicts, for those that have conflicting names I create a separate folder and put both of them in it, then I'll have to change their address manually and my automation doesn't work). So here's how I do migration for those that are not exceptions:

Redownload all the .torrent files I have the files for.
Put all of them in a single directory. Now this directory contains all the .torrent files my qBittorrent client needs.
Press (Alt + O) inside qBittorrent (or go to Tools -> Preferences inside it).
From the left pane choose Downloads.
Under "Saving Management" change the "Default Save Path" to the folder that contains all your downloaded files in a single directory. This is where the actual downloaded files are, not where the .torrent files are. These are two separate directories.
Now go a little below, look for "Automatically add torrents from:"
Press "Add" and add your folder that has all your .torrent files in it, press "OK", now all your torrents are automatically added to qBittorrent without any hassle, directing it to look at Default Save Path for the files.

If all goes well, your qBittorrent will realize that files are already downloaded, if it doesn't, then you've probably made a mistake, or have changed the name of the folders/files.

For my method to work, or for any torrent client to realize you're pointing to an already downloaded file, it's really important not to change the file/folder names at all. The name in the torrent file and the folders/files on your PC should match. If you have changed the names or have made an arbitrary folder structure, you need to ask AI to write you a python script to reverse your directory structure (for example move everything from A B C D … Z folders back to a single directory) or if you've really changed everything, to extract the folder/file names from torrent files and automatically revert them back to normal.

مقایسهٔ مدل‌های زبانی بزرگ در ترجمه

Mon, 11 Aug 2025 00:02:39 +0330

یکی از دوستان یک هوش مصنوعی معرفی کرد به آدرس z.ai که خواستم امتحانش کنم، برای همون متن همیشگی ترجمه‌ام رو بهش دادم و توی ترجمه افتضاح بود. متن انگلیسی زیر مربوط به کتاب How We Change ه:

You’re eager to make the change. You know all the ways it will benefit you. Your life will be smoother, happier, more successful; you’ll finally reach that perfect crow pose, lose that beer belly, schedule your time better, finally get out of the house and meet your perfect match, take that long-awaited step into a new career. The change will make you proud, raise your self-esteem, align your life with your values, bring you fulfillment and a sense of accomplishment. So you plan. You set up a daily schedule, enlist the help of a trusted ally, set reminders on your cell phone, buy a journal so you can record your successes. This time, you’re going to do it.

عبارت that perfect crow pose رو اگر ترجمه کنیم «حرکت بی‌نقص کلاغ» اشتباه میشه ترجمه و باید حتما رسوند که منظور در یوگاست چون توی انگلیسی مشخصه pose به یوگا اشاره داره ولی «حرکت» توی فارسی نه.
کلمه journal فارسیش خوب در نمیاد و خیلی از هوش‌مصنوعی‌ها اشتباه کردن سرش. «دفترچه روزنامه»‌ مثلا اشتباهه و «دفترچه» ترجمه بهتریه و «دفتر یادداشت روزانه»‌ از همه بهتره.
در آخرین خط: This time, your doing it. اگر به صورت ساده ترجمه بشه به «این دفعه انجامش میدید» اشتباهه چون با اینکه حرف تاییدی توش به کار نرفته تاکید توی انگلیسیش مضمره و حرف تاکیدی باید بیاد، که بعضی از هوش‌مصنوعی‌ها موفق بودن توش.
هیچ کدوم از هوش مصنوعی‌ها نتونستن ترجمهٔ beer belly که فارسیش میشه شکم عرق‌خوری رو در بیارن متاسفانه و همه نوشتن شکم آبجو. در این بین مدل gpt-4o که شکم عرق‌خوری رو ترجمه کرده شکم啤酒خوار از همه فاجعه‌تر بود. که 啤酒 در چینی میشه آبجو واقعا ولی خب توی ترجمه فارسی جاش نبود‌ :)
بعضی از هوش‌مصنوعی‌ها اشتباهی proud رو مغرور ترجمه کردن که توی این پاراگراف معنی افتخار داره.

بخوام امتیاز بدم بهترین ترجمه 🥇برای Gemini 2.5 Pro بود و بعد از اون 🥈 Deepseek و بقیهٔ ترجمه‌ها بابت اشتباهات فاحش ارزش خوندن نداشتن.

پاسخ همهٔ هوش مصنوعی‌ها رو اینجا گذاشتم.

How to connect to a bluetooth device using cli in GNU/Linux

Sat, 26 Jul 2025 01:02:24 +0330

Use bluetoothctl!

bluetoothctl
# [bluetooth]# power on
# [bluetooth]# agent on
# [bluetooth]# default-agent
# [bluetooth]# scan on
# … wait until you see 11:22:33:44:55:66 …
# [bluetooth]# pair 11:22:33:44:55:66
# [bluetooth]# trust 11:22:33:44:55:66
# [bluetooth]# connect 11:22:33:44:55:66

If you have a problem with your device:

sudo systemctl stop bluetooth # assuming you have systemctl, otherwise use your daemon manager's equivalen command.
sudo rm -rf /var/lib/bluetooth/AA:BB:CC:DD:EE:FF/11:22:33:44:55:66 # only if you have a serious problem with the device
sudo systemctl start bluetooth

وصله‌زدن به فایل‌های باینری و دور زدن «بوت امن»‌ با چت‌جی‌پی‌تی

Sun, 08 Jun 2025 22:58:09 +0330

از هوش مصنوعی انتظار خیلی چیزها رو داشتم ولی این یکی رو نه.

یک شخصی یک تبلت پاناسونیک با معماری پردازندهٔ x86 (یعنی معماری پردازندهٔ مشابه اکثر کامپیوترهای امروزی) داشته و تونسته روش به‌جای اندروید،‌ یک توزیع لینوکسی بریزه. تا اینجا خیلی چیز عجیبی نیست. تغییر سیستم عامل گوشی‌ها و تبلت‌ها کار آنچنان سختی هم محسوب نمیشه خصوصا اون‌هایی که معماری x86 دارن. جایی که عجیب و هیجان انگیزه اینه که شرکت پاناسونیک برای اینکه کسی نتونه سیستم عامل تبلت رو تغییر بده، از مکانیسم امنیتی Secure Boot استفاده می‌کرده. یعنی Firmware (سفت‌افزار!) فقط سیستم‌عامل اندروید ساخت خود پاناسونیک رو بوت می‌کرده. حالا یک نفر اومده کل firmware رو به‌صورت سخت‌افزاری کپی کرده، آپلود کرده و داده به ChatGPT و ازش خواسته که فایل باینری!! رو جوری تغییر بده که Secure Boot غیرفعال بشه. چت‌جی‌پی‌تی هم این کار رو کرده و اون شخص تونسته با موفقیت روی تبلت سیستم‌عامل دلخواهش رو بریزه.

این خبر برای من واقعا عجیب بود چون انتظار اینکه هوش مصنوعی بتونه متن رو به خوبی بفهمه رو همگی داریم ولی فهمیدن و تغییر آنی صفر و یک های یک برنامه‌ی کامپایل‌شده و اجرایی یک مرحله‌ی خیلی خفن دیگه است.

استفاده‌ی ویندوز از ری‌اکت نیتیو

Thu, 29 May 2025 16:30:37 +0330

ویندوز داره واقعا سیستم‌عامل جالبی می‌شه.

معمولا هر شرکتی میخواد برنامه‌ای بنویسه، از زبان بومی همون سیستم‌عامل استفاده می‌کنه تا سریع‌تر اجرا بشه. مثلا:

تلگرام دسکتاپ با زبان‌ C++ نوشته شده
تلگرام اندروید با جاوا نوشته شده (و به طرز بانمکی برای افزایش سرعتش مقدار زیادی C هم داره)
تلگرام iOS با Swift نوشته شده (و C و Objective C هم داره)

خلاصه هرکسی بهترین عملکرد رو می‌خواد با زبان بومی کد برنامه‌اش رو می‌نویسه.

در مقابل میشه عملکرد رو فدای سرعت توسعه‌ی برنامه کرد و یک کد رو برای همه‌ی سیستم‌عامل‌ها نوشت. مثلا اگر فیلترشکن هیدیفای رو دیده باشید، اون با Flutter ساخته شده و کد تقریبا یکسانی روی ویندوز، لینوکس و اندروید و iOS اجرا می‌شه. منتهی برنامه‌اش به طرز قابل توجهی نسبت به برنامه‌های بومی کندتره.

کدهایی که با React Native یا Flutter نوشته بشن قابل‌حمل‌ترن و روی سیستم‌عامل‌های مختلف با اندک تغییرات اجرا میشن ولی در مقابل کندترن.

حالا مایکروسافت تصمیم گرفته با React Native اجزای خود ویندوز رو بنویسه، یعنی خودش از امکانات بومی خودش استفاده نکرده و عملکرد بدتری رو ارائه داده. علت این کار رو هم اعلام کرده که در قسمت مدیریت حساب کاربری مایکروسافت، حال نداشتن جداگانه هم برای سایتشون کد بزنن، هم برای ویندوز. این شده که راه راحت و مزخرف کد زدن با React Native که نیازمند مفسر جاوااسکریپته و کندتره رو انتخاب کردن.

Signed HTTP Exchanges

Sun, 20 Apr 2025 21:14:11 +0330

Today I learned about Signed HTTP Exchanges. It makes caching so much easier. But the question that remains unsolved is: how can we have both caching and autonomous cache servers like Google and reliable information collection from how many times our data has been seen.

Bubble Sort

Here’s a quick and dirty C code that I wrote for Mini-Max Sum in HackerRank.

#define ARR_COUNT_MAX 5
void miniMaxSum(int arr_count, int* arr) {
 long int sorted_array[ARR_COUNT_MAX]={0};
 bool needMore=false;
 for(int i=0;i<arr_count;i++){
 for(int j=0;j<arr_count-(i+1);j++){
 if(arr[j]>arr[j+1]){
 int temp=arr[j];
 arr[j]=arr[j+1];
 arr[j+1]=temp;
 needMore=true;
 }
 }
 if(!needMore){
 break;
 }
 needMore=false;
 }
 // the question always had 5-element arrays.
 printf("%ld %ld",(long)arr[0]+arr[1]+arr[2]+arr[3],(long)arr[4]+arr[3]+arr[2]+arr[1]);
}
