Pseudo-historical project about 1912 unit record equipment computation aka the "Symbolic Analyst Processor" full stack!

(above pictures emulate the looks of what this tech stack documentation and actual use may look like, still very early in the process though)

It is still coming together by my head as I write infodump notes and research various aspects of the whole time, (including the WIMP & MERN/MEAN stack) but yk, things are coming together nicely to give some milestone project mid-way between my current phase in life and the next where I go develop a fully alternative INTJ lively stack of tools. Explanations, history dives, lively reaction studies and a couple more content suggestions related to it are on the way.

Behold, the infodumps

"Top-bottom and back up workflow" 1910 / 1912 Unit Record Equipment Tabulator Computation "Bundle" Project (Pflaumen & Utalics' SymbolicAnalystProcessor)

Back to the point

The list is far from exhaustive or finished, as life is so much more than meets the eye. But this should be a good start to remind myself what I am working towards, a full revamp of the last ~120 years of history with much attention and care put into making it as satisfying to me as possible, despite the very probable scenario where people take the ideas and incorporate only some of such "modules" in their own workflows. Which is fine but not taking the whole package (and only specific modules) is eventually gonna be a major learning experience for me considering the reason I revamp it all beyond control freak stuff is literally to provide less exclusive / less invasive tools that anyone can learn and customize despite being very... idiosyncratic yk.

Still welcoming suggestions and constructive criticism for such big time, I hope those textual infodumps I do every so often don't bother you too much... Cya soon!

[shin6174]

I use many devices.

MacBook 12inch, for the study of Swift code.

MacBook Air 13inch, for the study of the other programming languages, posting this blog, and the use of JWcad.

iPad Pro 12.9inch, for the house designing.

iPad mini 5, for Bullet Journal.

iPhone SE3, mainly for the messages with my family.

iPhone 6S, for sharing music with my family.

Galaxy A20, for the study of Linux, especially Ubuntu Touch.

Apple Watch SE2, for managing my health; sleeping log, step counting and more, and not for touching iPhone frequently.

That’s all, but these are only my devices. My family also have their own ones. So we are necessary to have many of charging plugs in the house, in the right place.

It’s in the closet and on the kitchen board in my house. Charging stations may have to be considered well when we design our houses. When I design houses I sometimes suggest to my costumers that they make a charging station somewhere in their houses. But they often say that they don’t need it. Only one time, a customer said to regret that they don’t make it.

How about you? If you make a charging station, where do you make it?

Linux Performance Tuning and Optimization

Red Hat Certification, Linux performance tuning and optimization are essential for maximizing the efficiency and responsiveness of a Linux system. Here are key strategies and considerations:

Monitoring Tools: Use performance monitoring tools like top, htop, and vmstat to identify bottlenecks and resource utilization. Tools like sar and Prometheus can provide historical data for analysis.

Kernel Parameters: Adjust kernel parameters via the /proc file system or configuration files in /etc/sysctl.d to optimize system behavior. Parameters like vm.swappiness, fs.file-max, and net.core.somaxconn can impact performance.

File System Optimization: Choose the right file system for your workload (e.g., ext4, XFS, or ZFS). Tune file system options like block sizes, journaling, and mount options for your specific use case.

I/O Optimization: Use hdparm or fio to test and optimize disk I/O. Implement techniques like RAID and SSDs for improved disk performance. Set read-ahead and I/O scheduler options appropriately.

Memory Management: Adjust memory settings, such as swappiness and transparent huge pages, to optimize RAM usage. Use vmstat to monitor swap activity.

CPU Tuning: Configure CPU governors to manage CPU frequency and power usage. Tools like cpufrequtils and tuned help optimize CPU performance.

Network Optimization: Tune network settings like TCP congestion control algorithms and buffer sizes. Tools like ifconfig and ethtool can help manage network interfaces.

Service Optimization: Review and optimize services running on your system. Disable unnecessary services, and configure service parameters for efficiency.

Security Measures: Implement security best practices to protect against resource-intensive attacks, such as denial-of-service (DoS) attacks.

Load Balancing: Use load balancing tools like HAProxy to distribute workloads across multiple servers for better performance and redundancy.

Web Server Optimization: For web servers like Apache or Nginx, adjust settings, such as worker processes and connections, to handle varying loads efficiently.

Database Tuning: Optimize database performance by configuring indexes, query caching, and buffer pool sizes. Tools like mysqltuner can assist in database tuning.

Regular Maintenance: Schedule routine maintenance tasks like disk defragmentation, log rotation, and software updates to prevent performance degradation over time.

Benchmarking: Periodically run benchmarks and performance tests to evaluate the impact of changes and improvements.

Documentation: Maintain documentation of changes and configurations to track the impact of optimizations and facilitate troubleshooting.

Performance tuning and optimization in Linux are ongoing processes that require monitoring, analysis, and adaptation to meet the specific requirements of your system and workloads. Regularly review and adjust configurations to ensure optimal performance.

re drivers: they're specific to the operating system! your Linux install absolutely could have non-working drivers while your Windows system has working ones.

re the general Manjaro and Thinkpad situation: I ran Manjaro for a while, but kept on getting lockups or kernel panics (probably what you're experiencing, the screen is frozen and the caps-lock key is blinking) very frequently. I think it's a general problem with Manjaro using very new, experimental versions of the Linux kernel. Now I've switched to Debian, and I have yet to experience a kernel panic after years of use. Debian software is a little older but the stability is well worth it for me.

re options for getting a system that works: when I was using Manjaro, there was an option in the boot screen (the GRUB menu) to boot from older kernel versions. Not sure if you have that, it might be under an "advanced options" thing. Usually I could find something four or five versions back that was stable and worked okay. You will probably be fine with the second-newest version (if the newest version is the only one that crashes).

re info/logs/etc: there are a few commands for this. For a lot of output about hardware, you'll want to install and run lshw (terminal command). You can redirect the output into a file: "sudo lshw > lshw-output.txt" (then you can share the file with people). For crash logs, run "sudo journalctl -b -1" (this will show you the system journal from your last boot, start-to-finish.) There will be lots and lots of output; it might be better to run "sudo journalctl -b -1 --no-pager > journalctl_log.txt" and then look at the resulting text file later. You can send me the file (put it on pastebin and send a link) and I can highlight the relevant portion for the issue you're facing, if you'd like. Also feel free to DM me with any other questions.

general strategies/tips n tricks: if I were you, I would create a bootable live Debian ISO (not just an installer) from Windows and boot off of it. It won't install anything on your disk, it just lets you take a look around in a stable Linux environment. You can run lshw from there, but the listed drivers will be different than the ones you're using on Manjaro (still very helpful for knowing exactly what hardware you have!) You can also run journalctl commands with a flag that points them at a certain partition (your Manjaro one) and they'll grab the journal off of the disk! And you can mount your Manjaro partition and look at config files, log files, etc. All in all a good diagnostic tool.

Does anyone know anything about Linux, specifically the Manjaro distro on a Lenovo ThinkPad? My distro stopped working entirely last week when I got back from my trip. I've tried researching it but I'm not having much success. The distro will boot but then freeze entirely within a minute or two. I have a dual-boot; I'm actually currently on my Windows 10 OS. (I really miss the tools that I had on Manjaro to unfuck my Tumblr dash. T_T) I thought perhaps the issue was my video driver, but wouldn't that mean that my Windows 10 OS wouldn't work either? And I don't know how to adapt kernals, especially if my Manjaro distro won't even stay operational long enough to get to the settings. Every Linux forum asks for computer stats but, other than the basics like brand etc., I don't know how to find those either.

I want to solve this myself but it's become so frustrating.

Great idea! I’d actually thought about this before, and you convinced me to try it out. So, I modified the command to this:

sleep 60 && sudo bash -c 'echo "0" > /sys/bus/pci/devices/0000\:01\:00.0/d3cold_allowed'

Doing this changed the result… to something new… again. Now the machine brings me to the unlock screen, and it functions as normal. I can type in my password and hit enter. The loading pinwheel then appears beside the password box and the entire system freezes for 1-2 minutes, maybe longer.

After this the screen flashes black for a split second before finally logging me into my desktop. From there, the cursor corruption/no image “gray square” happens again. Any attempt to launch an app results it immediately failing and giving me the error

Failed to launch “App” Failed to execute child process “/bin/sh” (Input/output error)

If I open an app before I shut the computer’s lid, when I open it back up and make the window active again, it will crash in a weird limbo state where the dock show’s it’s closed, no windows can be found, BUT the menu bar shows the app is still active.

After trying to shutdown with the GUI (Zorin Menu) I got this:

After trying to force something to happen by using the three-finger trackpad swipe to activate the app exposé (that’s its macOS name; idk the Linux name. It’s like app switcher or something), I got the same

systemd-journal[nnn]: Failed to write entry…Input/output error systemd-journal[nnn]: Failed to rotate…Read-only file system

error that I was getting before.

Here is what that crash looks like:

So we’ve made progress… but I’m not sure if it’s good progress. Im gonna re-tag this so hopefully people will the additional info.

So I have a Linux problem, and I'm just gonna post it here. I dunno if I have the reach for this, but if you know a potential fix, I will gladly accept it:

Basically, I run Zorin OS 17.2 Core on my Mid-2017 MacBook Pro (Two Thunderbolt Ports). This computer has been hell to make work, but after years of fiddling and finding drivers and terminal commands, it works almost like OEM.

My last problem with this machine, and the only thing that does not function like it's OEM, is the Sleep/Wake function. This is a known issue with 2016 and newer MacBooks on Linux; However, there are workarounds.

Namely, I found a kernel parameter that prevents Deep sleep and only allows the computer to go into s2idle when the lid is shut. This isn't great because it means the dies quickly and gets hot when the lid is shut, but I can't really do anything about it. This did, however, fix an issue I was having where the audio would just stop working if I ever shut the lid.

The final issue was getting the computer to wake up on its own. Every time I start the computer up (not waking it up; only powering it up from a complete shutdown) I have go into terminal and run this:

sudo bash -c 'echo "0" > /sys/bus/pci/devices/0000\:01\:00.0/d3cold_allowed'

I don't know what this command does, but without it, the machine will just never wake up. If you close the lid without running this at initial startup, it cannot be woken back up until it is rebooted.

That's not really a problem, since it's only once per reboot, and I don't reboot my laptop very frequently.

You know what would really make this even more seamless, though? If I could run this command using Ubuntu's startup applications menu. That way, I wouldn't have to manually open terminal every boot just to run this command. It would just run automatically, and I'd never have to worry about it. It would work like OEM! (Minus the less efficient sleep state.)

However, I can't do that. I've tried that. In fact, I have that exact command in my Startup Applications app, as we speak.

Any time I start the computer up and DON'T manually run the command, if I shut the lid, the computer sleeps. It will, however, wakeup (unlike if the command had never been input). HOWEVER. Unlike running the command in terminal, when it finally wakes up, the cursor photo changes into a gray square, my Night Light settings are reset, my wallpaper changes to black, my system accent color is changed to default, and any time I click inside the password box to login, the field immediately becomes inactive again. It doesn't stay active long enough for me to even get two letters typed. All this happens while "Authentication Error" rapidly and randomly flashes below the password box.

Eventually, if I don't force shut down the machine, it'll crash. It'll throw me into terminal mode, and it'll infinitely repeat an error claiming it could not write to some 'systemd jounral' thing because the operating system is in read-only mode. After that it'll either repeat that error over and over, creating endless lines in terminal mode, or it'll just freeze, and I have to restart the laptop either way. So, my question is:

WHY.

Why does running this command in terminal and running it via Startup Application have different results, and is there any way to fix it??

Some less often asked questions (2 of 2)

part one

26: Do you like to dress fancily?

It's nice to look nice every once in a (great) while, but (a) I'm bad at... clothes and (b) I'd rather be comfortable

27: If you could bring back any style of fashion from history, what would you bring back?

I am not into fashion enough to answer this, but definitely not any time before it was acceptable for women to wear pants

28: Do you like to dance?

I genuinely don't know how to dance in a way that is not choreographed

See the answer to question #1. Oh, and add about a half acre of land for my future doggos to run around on, with some trees for privacy.

37: Do you prefer playing on a computer or a console?

It's a toss-up... Probably computer though, since that’s what I’ve used most.

Logs on any Linux system are critical for analyzing and troubleshooting any issues related to system and applications. With the help of tools like Graylog, you can easily ship these logs to a centralized platform for easy visualization. In this guide, we will look at how to Configure Rsyslog Centralized Log Server on Ubuntu 22.04|20.04|18.04LTS. On Linux, by default, all log files are located under /var/log directory. There are several types of log files storing varying messages, which can be cron, kernel, security, events, users e.t.c. Mostly these logs file are controlled by rsyslog service. On recent systems with systemd, some logs are managed by journald daemon and they are written binary format. These logs are volatile since they are written to RAM and doesn’t withstand system reboot. They are often found on./run/log/journal/ But note that journald can also be configured to permanently store log messages by writing to file. Configure Rsyslog Log Server on Ubuntu 22.04|20.04|18.04 We’re going to configure rsyslog server as central Log management system. This follows the client-server model where rsyslog service will listen on either udp/tcp port. The default port used by rsyslog is 514. On the client system, rsyslog will collect and ship logs to a central rsyslog server over the network via UDP or TCP ports. When working with syslog messages, there is a priority/severity level that characterizes a log file. Namely: emerg, panic (Emergency ): Level 0 – This is the lowest log level. system is unusable alert (Alerts):  Level 1 – action must be taken immediately err (Errors): Level 3 – critical conditions warn (Warnings): Level 4 – warning conditions notice (Notification): Level 5 – normal but significant condition info (Information): Level 6 – informational messages debug (Debugging):  Level 7 – This is the highest level – debug-level messages Rsyslog is installed by default on a freshly installed Ubuntu system. If for any reason the package is not installed, you can install it by running: sudo apt-get update sudo apt-get install rsyslog When installed, check service to see if it is running: $ systemctl status rsyslog ● rsyslog.service - System Logging Service Loaded: loaded (/lib/systemd/system/rsyslog.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2018-07-18 11:30:10 UTC; 4 days ago Main PID: 903 (rsyslogd) Tasks: 4 (limit: 4704) CGroup: /system.slice/rsyslog.service └─903 /usr/sbin/rsyslogd -n Configure rsyslog to run in Server Mode Now configure rsyslog service to run in server mode: sudo vim /etc/rsyslog.conf Uncomment the lines for udp and tcp port binding: module(load="imudp") input(type="imudp" port="514") # provides TCP syslog reception module(load="imtcp") input(type="imtcp" port="514") If you would like to limit access from to specific subnet, IP or domain, add like below: $AllowedSender TCP, 127.0.0.1, 192.168.10.0/24, *.example.com You can add above line after input(type="imtcp" port="514") line. Remember to substitute given values with correct ones Create a new template for receiving remote messages Let’s create a template that will instruct rsyslog server how to store incoming syslog messages. Add the template just before GLOBAL DIRECTIVES section: $template remote-incoming-logs,"/var/log/%HOSTNAME%/%PROGRAMNAME%.log" *.* ?remote-incoming-logs & ~ The received logs will be parsed using the template above and stored inside directory/var/log/. The file naming follows the convention: %HOSTNAME% and %PROGRAMNAME% variables, i.e the client hostname, and client facility that produced the log message. The & ~ instructs rsyslog daemon to store the log message only to a specified file. Other variables that can be used include: %syslogseverity%, %syslogfacility%, %timegenerated%, %HOSTNAME%, %syslogtag%, %msg%, %FROMHOST-IP%, %PRI%, %MSGID%, %APP-NAME%, %TIMESTAMP%, %$year%, %$month%, %$day% Restart rsyslog service for the changes to take effect:

sudo systemctl restart rsyslog Confirm if the service is listening on configured ports: $ ss -tunelp | grep 514 udp UNCONN 0 0 0.0.0.0:514 0.0.0.0:* users:(("rsyslogd",pid=15220,fd=5)) ino:441816 sk:2 udp UNCONN 0 0 [::]:514 [::]:* users:(("rsyslogd",pid=15220,fd=6)) ino:441817 sk:5 v6only:1 tcp LISTEN 0 25 0.0.0.0:514 0.0.0.0:* users:(("rsyslogd",pid=15220,fd=7)) ino:441820 sk:a tcp LISTEN 0 25 [::]:514 [::]:* users:(("rsyslogd",pid=15220,fd=8)) ino:441821 sk:11 v6only:1 Configure Rsyslog firewall If you have ufw firewall service running, allow rsyslog firewall ports: sudo ufw allow 514/tcp sudo ufw allow 514/udp Configure Rsyslog as a Client Once you’re done configuring rsyslog server, head over to your rsyslog client machines and configure them to send logs to remote rsyslog server. sudo vim /etc/rsyslog.conf Allow preservation of FQDN: $PreserveFQDN on Add remote rsyslog server at the end: *.* @ip-address-of-rsysog-server:514 You can also use FQDN instead of Server IP Address: *.* @fqdn-of-rsysog-server:514 The above line will enable sending of logs over UDP, for tcp use @@ instead of a single @ *.* @@ip-address-of-rsysog-server:514 #OR *.* @@fqdn-of-rsysog-server:514 Also add the following for when rsyslog server will be down: $ActionQueueFileName queue $ActionQueueMaxDiskSpace 1g $ActionQueueSaveOnShutdown on $ActionQueueType LinkedList $ActionResumeRetryCount -1 Then restart rsyslog service sudo systemctl restart rsyslog Also check: Manage Logs with Graylog server on Ubuntu 18.04 How to Install Graylog 2.4 with Elasticsearch on CentOS 7.

Comando mkfs no Linux (formata disco) [Guia Básico]

O comando mkfs no Linux formata a partição criada pelo fdisk / gdisk / parted com o sistema de arquivos. O tipo de sistema de arquivos é definido pela opção –t e são os formatos nativos ext2, ext3, ext4, fat, vfat, minix, msdos e xfs. Os comandos mke2fs e mkdosfs são variações do mkfs. O mkfs possui algumas variações que permitem escolher o tipo de sistema de arquivos diretamente: $ ls -l /usr/sbin/mk*lrwxrwxrwx 1 root root      8 ago 29 22:48 /usr/sbin/mkdosfs -> mkfs.fat-rwxr-xr-x 4 root root  96328 jul 26  2018 /usr/sbin/mke2fs-rwxr-xr-x 1 root root  11432 jul 26  2018 /usr/sbin/mkfs-rwxr-xr-x 4 root root  96328 jul 26  2018 /usr/sbin/mkfs.ext2-rwxr-xr-x 4 root root  96328 jul 26  2018 /usr/sbin/mkfs.ext3-rwxr-xr-x 4 root root  96328 jul 26  2018 /usr/sbin/mkfs.ext4-rwxr-xr-x 1 root root  28512 ago  2  2018 /usr/sbin/mkfs.fat-rwxr-xr-x 1 root root  83824 jul 26  2018 /usr/sbin/mkfs.minixlrwxrwxrwx 1 root root      8 ago 29 22:48 /usr/sbin/mkfs.msdos -> mkfs.fatlrwxrwxrwx 1 root root      8 ago 29 22:48 /usr/sbin/mkfs.vfat -> mkfs.fat-rwxr-xr-x 1 root root 372448 jan 24  2019 /usr/sbin/mkfs.xfs Dependendo da variação que você escolher, o mkfs pode ter mais ou menos opções. De maneira geral, as opções possíveis do comando mkfs são: - -t: Informa qual o tipo de formatação a partição deverá ser - -c: Verifica a existência de bad blocks (defeitos) no dispositivo; - -L: nome Configura o nome do dispositivo; - -n: nome Configura o nome do dispositivo para o formato msdos; - -q: Faz com que o mkfs trabalhe com o mínimo de saída no vídeo possível; - -v: Faz com que o mkfs trabalhe com o máximo de saída no vídeo possível; - -m: Percentual de disco reservado Uma opção interessante do mkfs é o “-m percentual” que permite reservar um espaço do disco em percentual  para evitar o travamento do sistema em caso de disco cheio. A ideia é o sistema operacional alertar que o disco está cheio para os usuários comuns, ANTES do disco estar realmente completamente cheio. Isso permite que o sistema continue funcionando por um tempo até que o administrador possa tomar alguma medida para evitar que um disco realmente cheio trave o funcionamento do sistema ou ocasione perda de dados.

O Linux suporta vários sistemas de arquivos e sua escolha depende muito da utilidade que se dará ao sistema e o tipo de disco. Os discos formatados com ext2, ext3 e ext4 possuem uma gama grande de ferramentas. Como utiliza um tamanho de bloco fixo, não são bons sistemas de arquivos para pequenos arquivos, pois podem consumir muito disco desnecessariamente. Por exemplo, o ext4 usa como padrão blocos de 4K. Se você tem muitos arquivos pequenos como de 1k, cada arquivo vai usar um bloco inteiro de 4k, mesmo que seu tamanho seja menor que isso. O XFS por sua vez é excelente na execução de operações paralelas de entrada/saída (E/S) com uso de vários discos físicos, pois foi desenhado para alto desempenho de estações gráficas. Ele é ideal para aplicações que editam imagens e vídeos. Já o BTRFS parece ser a escolha mais acertada, já que permite snapshots, compactação, desfragmentação e tantas outras vantagens, mas nem sempre disponível em todas as distribuições.
