I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.

So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.

It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.

Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).

Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!

The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.

Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.

So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.

There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

Finally deleted WhatsApp!

Bind's top {number} dev tools to make your 2018 easier!

//note 0: feel free to add your own
//note 1: no ides, only stuff thats useful for everyone

0) vscode, it got significantly better after the latest updates and is very versatile
1) gitkraken, now i use sourcetree because of the jira integration but kraken is available for linux too so
2) scaleway, they provide really cheap servers for whatever you want, easy to install images (docker too)
3) protonmail, an encrypted mail service that works a lot better than gmail (tutanota is a close 2nd but has a weeb name)
4) telegram, if you can, tell your team to ditch slack, because telegram is a lot more lightweight and even if you dont, just the channels make it worth giving it a shot
5) steemit, a blockchain based website where the users write the articles, you can find some good reads there (and photography if you like that stuff)
6) a dildo because it wouldnt be a bindview content without out of context penile objects

Am I the only one who thinks telegram messenger is much better than others like whatsapp and Skype.

Slack.

A product which I hated in the beginning, is something that I have started admiring now.

Like Telegram, things just kept improving without bloating the shit out of the product.

What's interesting is that they came up with Huddle, an instant call and connect feature where they support Audio and Screen sharing.

Totally a game changer and a Zoom killer because Zoom could be even better in terms of UX.

Functionally, hands down, Zoom is flawless but slowly it's becoming an overkill.

I am excitedly waiting to see how both of these compete because Slack surely has an upper hand in this game.

So I met this person via a social platform.

They were absolutely silly and weren't able to hold a conversation. So I, like a normal person, just stopped trying to keep things alive.

Over the years, I have realised and learnt that if a person is interested in being friends, they'd put in efforts and I alone will not have to drag things on my shoulder.

I started cutting out people right, left, and center who I felt were taking advantage of me or using me in some way or another.

I ended up saving a lot of time and energy. I no longer feel drained or anxious about something not working out. Not dragging saved me from draining.

Anyway, they reach out to me again after few weeks and I was like let's give it a try to establish a friendship, because befriending people is my weak point.

The cycle repeats. At first I thought it must be because of the asynchronous nature of the platform so I drop my Telegram Id in case they preferred an IM approach.

I swear in the name of sweet lord, the retard does the same behaviour. So, I stopped communication.

And one fine day, the person tells me that they lack social skills and want to learn how to make friends and stuff.

Very fair point. So, me being me, gave them a few tips and critically pointed out their behaviour on how they reply with a one liner after every 2 or 3 business days.

Absolutely no change in their behaviour. They kept texting me the same.

At this point, I was like why am I doing it? I could find better people easily. Because for me, communication is everything. I cannot function without a good communication between two living beings.

So, I asked them why are they even trying to learn social skills when they barely implement it and don't want to change to which they reply saying that so they can use it to befriend people and network to getter better job opportunities.

I fuck them off.

And fuck such people who have intentions, are not clear enough about it, and play people for their own selfish gains.

And this where another learning I got from @scout is have boundaries.

Why do all good people in my life leave? Damn it! I need those good people back and be friends with them and not retards who cannot even communicate beyond one liner.

The first fruits of almost five years of labor:
7.8% of semiprimes give the magnitude of their lowest prime factor via the following equation:
((p/(((((p/(10**(Mag(p)-1))).sqrt())-x) + x)*w))/10)

I've also learned, given exponents of some variables, to relate other variables to them on a curve to better sense make of the larger algebraic structure. This has mostly been stumbling in the dark but after a while it has become easier to translate these into methods that allow plugging in one known variable to derive an unknown in a series of products.

For example I have a series of variables d4a, d4u, d4z, d4omega, etc, and these are translateable now, through insights that become various methods, into other types of (non-d4) series. What these variables actually represent is less relevant, only that it is possible to translate between them.

I've been doing some initial learning about neural nets (implementation, rather than theoretics as I normally read about). I'm thinking what I might do is build a GPT style sequence generator, and train it on the 'unknowns' from semiprime products with known factors.

The whole point of the project is that a bunch of internal variables can easily be derived, (d4a, c/d4, u*v) from a product, its root, and its mantissa, that relate to *unknown* variables--unknown variables such as u, v, c, and d4, that if known directly give a constant time answer to the factors of the original product.

I think theres sufficient data at this point to train such a machine, I just don't think I'm up to it yet because I'm lacking in the calculus department.

2000+ variables that are derivable from a product, without knowing its factors, which are themselves products of unknown variables derived from the internal algebraic relations of a product--this ought to be enough of an attack surface to do something with.

I'm willing to collaborate with someone familiar with recurrent neural nets and get them up to speed through telegram/element/discord if they're willing to do the setup and training for a neural net of this sort, one that can tease out hidden relationships and map known variables to the unknown set for a given product.

If you have a blog, How do you decide what to write and publish on it? And, How do I motivate myself to write posts?

Context: I created my blog/website on 29 September 2017. I had a few ideas on writing blog posts(Condition variables in Go, Serverless related stuff and a whole bunch of posts related to wireguard) but every time I have tried write a post, I learn there is someone else who has already written a post on it and probably better than what I could have done, So what is really the point of writing it? And, I feel very insecure about writing posts, I feel like, If I do write a post, every one will know, I don't know anything about **anything**. :( I know about imposter syndrome, But I don't think I have that. I work with a lot of realllly smart people and I don't know as much as them. So, I am actually an imposter.

edit: I am usually active on Telegram, IRC and I try to help out people. It's easier for me to help people in communities like that but doing the same thing with a blog makes me very uncomfortable.

Following some new nextjs tutorial to learn how to efficiently build a web chat app, the guy built it very solid, but is it efficient?

Im having mixed feelings about this approach. The way he did it is, for example when you click on a user (imagine it as a list of users from your contacts), it actually calls a route, which stores that in database, and once its done Then the route triggers lets say socket.io event to notify the frontend to update the UI.

Not only that but each new message that gets sent it actually calls a route which stores that message in database and once that's successful Then it emits a socket.io event to the frontend to fetch that message.

As you can imagine constantly calling routes like this Does induce small delays. Creating conversations, navigating, opening someones profile and especially sending messages, is NOT instantaneous. When you do it theres a small delay, giving the impression as if the app is SO large that it lags

But it doesnt lag, it just needs a few ms to store that in db so it can return the socket.io bidirectional message event. Which does make sense because what if the internet broke and the user immediately gets sent a message, but the message fails to get stored in database? Or db storage gets fucked or something else fails but socket.io works while db doesnt? The data then may be inconsistent. This approach fulfulls the single source of truth principle

So thats why im having mixed feelings about this approach particularly because of small delays. It is not instantaneous like whatsapp discord telegram signal viber etc the input UI freezes until the message is successfully sent

---

Of course this can be a UI/UX decision and can be handled differently even if the backend works like that.

My concern is is this approach valid?

My question is... I had an idea what if i emit socket.io event to send the message while in the background also call the route to store that message in db? This way not only would it work asynchronously but the message gets sent instantaneously, and if the backend fucks up to store it in db then the UI gets updated with message failed to get delivered, switching the socket.io into polling state. Is this a good (proper, efficient, better) way to do it or not?
