Random Access Memory 🤐

Medium long story about POP!_OS

TL;DR : A true K.I.S.S. OS. Very well designed UI. In general suitable for everyone. Any distro-hoppers MUST try out. If your current OS is already heavily customized to your needs, DON'T bother with POP. (Read till the end if you are on toilet, nothing to lose)

Backstory : I am never a fanboy of anything although I am loyal to the tools I use daily. So OS is also something I picked and use to meet my needs except when I was a student. My first linux experience was about a decade ago with ubuntu. Have tried almost all kinds of light-weight and minimal distros after that (lubuntu, arch, mint, puppylinux, fedora, centos and others I forgot) during my student years.

I like all things minimal. ("Keep It Simple Stupid" is my email signature.) When I started working, Windows became the sole OS I use since it met my needs better than others. Except that one time when I tried Elementary. Although I found it a good OS, it didn't get installed as a dual-boot. I don't find Elementary minimal. It is one of well designed OSs but I still think it can be improved. (Plus I had this weird feeling that it is similar to Mac OS)

At the start of this year, Widows alone was not enough for my needs. Decided to look for a minimal linux distro. My old i7 ASUS has 8GB RAM and roughly 250GB free storage. So I am not that worried about hardware requirements. My main struggle is downloading stuffs. (Few of you guys must know by now the speed of my internet LOL.) Well, even if I had a good speed, I will still look for minimal distro as first priority. So I went with minimal ubuntu image and xubuntu environment. Although I do not like the UI design, it is acceptable. Through out the years, I have configured it to suit my needs and currently pretty happy with it.

Thoughts on POP!_OS : To me, it is literally like meeting a young girl who is perfect for my life. She has the perfect body, beautiful face, amazing appearance and good manners. And she is young, of course there is a lack of experience issue. But it can be taught and she has a very high chance to become a wonderful lady if she continues like this. Only crap is I already have someone and in a committed relationship. So I could not go any further than introduction. I do save her contact and will keep in touch with her online. You know? Things change. Things always change somehow.

Researchers were able to store 3 bits of data per cell in phase-change memory, beating the previous limit of 1 bit per cell, IBM said. PCM competes with dynamic random-access memory.

So this very random thought pop up just now.

What if Satoshi is on devrant? 🤔

Not really a rant and not very random. More like a very short story.

So I didn't write any rant regarding the whole Microsoft GitHub topic. I don't like to judge stuff quickly. I participated in few threads though.

Another thing is I also don't use GitHub very much apart from giving 🌟 to repos as a bookmark. Have one hobby project there. That's all. So I don't worry that much. I'm that selfish and self concerned. :3

I was first introduced to version control system by learning how to use tortoisesvn around 2008. We had a group project and one of the guys was an experienced and amazing programmer unlike the rest of us. He was doing commercial projects while we were at our 1st and 2nd year. Uni had svn repo server. He taught us about tortoisesvn. He also had Basecamp and taught us how to use it as well. So that's how I learned the benefits of using versioning tools and project management tools. On side note, our uni didn't teach any of those in detail :3

After that project, I was hooked to use versioning tools. So until school kicked me out, I was able to use their svn server. When I was on my own, I had to ask Google for help. I found a new world. There are still free svn services that I can use with certain limited functions. That's not the new world; I found people saying how git is better than svn in various ways. It was around 2010,2011.

At first I was a bit reluctant to touch git because of all the commands in terminal approach. But then I found that there is tortoisegit. I still thank tortoisesvn creator for that. I'm a sucker for GUI tools. So then I also have to pick which git servers to use. Hell yeah, self hosted gitlab is the way to go man. Well that's what the internet said. So I listened. I got it up and running after numerous trial and error. I used it briefly. Then I came back to my country on 2012-2013; the land of kilobytes per minute (yes not second, minute).

My country's internet was improved only after 2016. So from 2013 to 2016, I did my best not to rely on internet. I wasn't able to afford a server at my less than 10 people, 12ft*50ft office. So I had to find alternative to gitlab which preferably run on windows. Found bonobo and it was alright. It worked. Well had crazy moments here and there when the PC running Bonobo got virus and stuff. But we managed. We survived. Then finally multi national Telecom corporates came to our country.

We got cheaper and faster mobile data, broadband and fiber plans. Finally I can visit pornhub ... sorry github. Github is good. I like it. But that doesn't mean I should share my ugly mutated projects to the rest of the world. I could keep using Bonobo but it has risks. So I had to think for an alternative. I remembered that gitlab didn't have cloud hosting service when I checked them out in the past. So I just looked into Bitbucket and happy with their free plans of 5 users and unlimited private repos. I am very very cheap and broke.

That's why I said I don't really care that much about the whole M$GitHub topic at the beginning. However due to that topic, I have visited GitLab website again and found out they have cloud hosting now and their free plan is unlimited users and unlimited repos. So hell yeah. Sorry BB. I am gonna move to cheaper and wider land.

TL;DR : I am gonna move to GitLab because of their free plan.

Don't know if you guys have this kind of boxed up stuff inside like me. I have good friends, I have a good gf, I have great family and nice colleagues. But there are still so many things I don't share with them, especially the negative feelings I usually possess. Even here I don't share all the deep dark stuff.

As much as I wanna share my true identify and personal info here, the reason I'm restraining myself from doing so is this is the only place where I can say whatever really I wanna say in my mind. Except my blog but then my blog doesn't have any reader.

MTP is complete garbage. I want mass storage back.

The media transfer protocol (MTP) occasionally discovers new creative ways of failure. Frequently, directory listings take minutes to load or fail to load at all, and it freezes up infinitely (until disconnected) when renaming an item, and I can not even do two things simultaneously.

While files are being moved, I can not browse pictures or watch videos from the smartphone.

Sometimes, files are listed with the date 1970-01-01 (Unix epoch) instead of their correct date. Sometimes, files do not appear at all, which makes it unsafe to move directories from the device.

MTP lacks random access. If I want to play a two-gigabyte 4K 2160p video and seek in the video, guess what: I need to copy it to my computer's local mass storage first because MTP lacks random access.

When transferring high numbers of files, MTP has to slooooowly enumerate (or "prepare" or "calculate the time of") them all, which might even take longer than mass storage would need for the entire process. This means MTP might start copying or moving the actual files when mass storage is already finished.

Today, the "preparing to move" process was especially slow: five minutes for around 150 files! How am I supposed to find out what caused this random malfunction?

MTP sometimes drives me insane. I want mass storage back, at least for the MicroSD memory card, which uses a widely supported file system.

Imagine a 2010 $100 Android phone is better at file transfer than a 2022 $1000 Android phone (or iPhone, for that matter).

It's 2022 and Firefox still doesn't allow deactivating video caching to disk.

When playing videos from some sites like the Internet Archive, it writes several hundreds of megabytes to the disk, which causes wear on flash storage in the long term. This is the same reason cited for the use of jsonlz4 instead of plain JSON. The caching of videos to disk even happens when deactivating the normal browsing cache (about:config property "browser.cache.disk.enable").

I get the benefit of media caching, but I'd prefer Firefox not to write gigabytes to my SSD each time I watch a somewhat long video. There is actually the about:config property "browser.privatebrowsing.forceMediaMemoryCache", but as the name implies, it is only for private browsing. The RAM is much more suitable for this purpose, and modern computers have, unlike computers from a decade ago, RAM in abundance, which is intended precisely for such a purpose.

The caching of video (and audio) to disk is completely unnecessary as of 2022. It was useful over a decade ago, back when an average computer had 4 GB of RAM and a spinning hard disk (HDD). Now, computers commonly have 16 GB RAM and a solid-state drive (SSD), which makes media caching on disk obsolete, and even detrimental due to weardown. HDDs do not wear down much from writing, since it just alters magnetic fields. HDDs just wear down from the spinning and random access, whereas SSDs do wear down from writing. Since media caching mostly invovles sequential access, HDDs don't mind being used for that. But it is detrimental to the life span of flash memory, and especially hurts live USB drives (USB drives with an operating system) due to their smaller size.

If I watch a one-hour HD video, I do not wish 5 GB to be written to my SSD for nothing. The nonstandard LZ4 format "mozLZ4" for storing sessions was also introduced with the argument of reducing disk writes to flash memory, but video caching causes multiple times as much writing as that.

The property "media.cache_size" in about:config does not help much. Setting it to zero or a low value causes stuttering playback. Setting it to any higher value does not reduce writes to disk, since it apparently just rotates caching within that space, and a lower value means that it just rotates writing more often in a smaller space. Setting a lower value should not cause more wear due to wear levelling, but also does not reduce wear compared to a higher value, since still roughly the same amount of data is written to disk.

Media caching also applies to audio, but that is far less in size than video. Still, deactivating it without having to use private browsing should not be denied to the user.

The fact that this can not be deactivated is a shame for Firefox.

Just had a meeting with a client. Client is a local company but they hired a new guy and he is a foreigner. They made a website with us. Since it is a typical corporate website with few pages and just text and images as content, we used WordPress.

The new guy is familiar with squarespace and asked me my opinion on using SS. I don't really find any issue and it was my reply. He seemed surprised and asked me "Wouldn't it be like losing your business?"

I have never considered developing WordPress as my business. Programming is my interest and profession. But my main passion is to provide solutions to anyone in need. In fact, there were many occasions where I told to clients they shouldn't buy our services and recommend other services including competitors.

He probably thinks I'm a strange guy.

!rant but story

Didn't participate in this week rant since the topic is not very relatable to me.

I rarely get truly inspired. There are people I envy. There are things I like. There are moments I go, oh awesome. That's about it.

I doubt myself that I have little bits of narcissist and sociopath traits. Maybe I am. 🤔

Showing a php and dual-boot guy the anti-php and anti-window posts might be an intentional algorithm. We never know. 💀

So I have a question to anyone familiar with the General Transit Feed Specification...

Why is the data provided in text files? Is there not a way to format the data to allow for random access to it?

Like I'm currently writing a transit app for a school project, and as far as I can tell, the only way to get all specific stops for a route, is to first look up all trips in a route, then look up all the stopids that are associated with a trip in stoptimes.txt (while also filtering out duplicates since the goal is to get stop ids, not specifically stop times) and then look up those stop ids in the stops.txt file.

The stoptimes file alone is over 500000 lines long, unless there is a way better way to be parsing the data that I'm not aware of? Currently I'm just loading the entire stoptimes file into a data structure in memory because the extra bit of ram used seems negligible compared to the load times I'm saving...

Would it be faster if I just parsed all the data once and threw it into a database? (And then updated the database once a month when the new data comes in?)
