> SQL could be improved somewhat by introducing composable query fragments with statically-typed interfaces. I begin by explaining two areas (testing and reusing business logic) where SQL does very poorly. Then I explain my solution, and how it addresses the problems.

Please please please I want those functors so badly. I don't have the energy to set up a test db for every damn project I start.

write your own sqlite implementation with these features. it sounds intimidating but it is not, the logic behind it is very simple

They don't accept patches from outside their circle. You need to be approved by the devs before you can even contribute with your code.

why do FP lovers always want to generalize the most random shit, like this, and why do they always want someone else to implement the stuff they want?

Testing. The other complaint is true tho

>>29500
? I'm saying you can write your own sqlite -type database, you don't have to go through the sqlite bureaucracy. that blog entry is a really beginner friendly introduction to database design. hell, I'm pretty sure you could easily write something better and more composable than sqlite just by using non-blocking i/o (so it could be integrated into event loops like libuv), I'm sure someone must have already done this

Terry Davis is such a tragic figure and TempleOS is legitimately impressive, but so much of the epic 4chan stuff around him is just "let's get this severely unwell man to scream the n-word because it's funny".

>needs some degree of linking/indirect adressing associated with that, right?
no. you just have to check that your programs don't overlap. they can and they will if you make a mistake

>represent a notable leap in complexity
it does because it makes it hard to change the .text section while the program is running (in principle you shouldn't be able to)

>>29308
>you just have to check that your programs don't overlap
I had a look at the code of a game (from https://archive.org/download/TempleOS_ISO_Archive/TempleOS_V5.03/Tos_distro_2017.11.20_19-52.iso) and it doesn't appear to be loaded at a fixed offset, the same program can be run as an arbitrary number of tasks. No virtual memory only means each program has to reside in core (TOS ostensibly implements timesharing and threading without multitasking).
>it does because it makes it hard to change the .text section
You would more-or-less have to load object code into W|X marked memory, which comes with the territory. Write protection on the .text segment only makes writing self-modifying code harder.

>>29309
>and it doesn't appear to be loaded at a fixed offset
you don't need fixed offsets to overlap. all programs and all cores share the same address space. the kernel and drivers do have fixed offsets, programs are allocated with malloc (often right next to each other), but because they share the address space you can overlap. here is terry explaining it himself

>No virtual memory only means each program has to reside in core
in main memory, it also means no protections, which would be considered a giant flaw in any consumer os but it is a feature in templeos. the point is that it isn't as impressive as you think, any compiler could do something similar in a similar environment

TempleOS BTFO's the linux kernel, Windows NT does, any project on osdev does

lets talk about windows 11 and how its better then all the other operating systems like windows 10 andd linux which are slow and suck

and before u get mad and start saying LIUNX IS BETTER WINDOWS IS STUPID just know this i tryed linux mint and it broke my computer really bad like it woulddnt turn on so i had to get windows put back on it but it was windows 10 so i upgraded to window s11 and now is so much better i like the new look and the feature is really not that bad guys!!!
4 posts and 1 image reply omitted.

OP it sounds like what happened when you tried to use Mint was your bootloader was not allowing a startup because you changed the operating system without getting it's permission to do so. Linux distros do have their issues but I am sure that's likely what happened.

>>29444
It isn't enabled in enterprise versions and the like because of that reason.

Windows 95 has yet to be surpassed. XP was aight.

I recently upgraded my w10 2019 ltsc iot to 2021 version
given how steam worked for gaming on linux and many games even work better now, I will prolly not ever go to 11 and go straight to linux when support finally stop, but I have quite some time still

Damn it, I do not want to switch to w11! I wonder if there's a way to get w11 Windows Defender without switching.

I started hosting an image board out of my house, in the past I've also hosted space station 13 servers. Hosting things from my bedroom has become a hobby of mine.
My ss13 is closed now due to disinterest and lack of a player base.
I'm in the process of setting up a home NAS.
I get a big thrill out of connecting to my homelab from my phone.
What else can I host from home that might actually be useful?

A forum.
A library.
A personal cloud drive.
A wiki.

Git forge.
Fediverse microblog.
Communications (XMPP/Mumble/email/IRC.)
Icecast Radio.

I want to tighten my opsec. I figured the best way is to try to get experienced hackers to try to bust me, as unwise as that might sound. is there a website, forum or community where you can ask people to pwn you?

>>24781
It's kinda hard, but I guess there are ways you could DIY. You either need to learn yourself or have someone (or some group, company, whatever) TRUSTABLE do a (paid) pentest on your devices and network for you (and it's expensive).
There are tools that could help you, tools that defensive/SOC and offensive security people use, like vulnerability and network scanners (Nessus, ), centralized monitoring tools, antivirus and EDRs (Endpoint Detection and Response software), binary/source code scanners for prevention and detection, traffic monitoring, packet inspection tools…
None of these tools are 100% reliable, they give false positives AND negatives.

get into a toxic and codependent relationship with a genuine crazy person. dump them and then see how hard it is for them to stalk you

>>24781
If you're not hosting anything, then other than having a good firewall most attacks would involve you explicitly doing (downloading/uploading) something no? Think phishing or PDFs; best way would be to upload a PDF in this thread, and you would inevitably download it etc.

>>29392
>most attacks would involve you explicitly doing (downloading/uploading) something no?
Most, but there are attacks that may exploit 0-day vulnerabilities (or 1-day vulns, or even old vulns if you don't update your shit) that do everything automatically, so the complexity of your defenses depends on your threat model.
A firewall with a whitelist could be useful but depends on the program(s) being exploited, the exploit(s) used and the privileges gained.

>>29389
BTW, I forgot to mention that there are LOTS of free and/or open-source security tools out there for offensive and defensive operations. In fact, some FOSS tools are the best ones in their categories. DYOR, or ask here if you want to know more.

> The original design concept of ThinkPad was created in 1990 by Italy-based designer Richard Sapper, a corporate design consultant of IBM and, since 2005, Lenovo.[7][8][9] Sapper is noted for the design of classic products such as the Tizio lamp for Artemide, office chair for Knoll, kitchenwares for Alessi and ballpoint for Lamy.[10][11] The design was based on the concept of a traditional Japanese Bento lunchbox revealing its nature only after being opened.[3][7][9] According to later interviews with Sapper, he also characterized the simple ThinkPad form to be as elementary as a simple, black cigar box and with similar proportions that offers a 'surprise' when opened

Why people jerk off everything that Apple shits out when all their designs are just bargain store Dieter Rams while an actual designer is behind Thinkpads is beyond me.

Macbook Air is cheaper than any Snapdragon X laptop which is pretty much the only other non-shit ARM laptop chipset.

Still downplaying the inconvenience of spare batteries even if you're just plugging a powerbank into the USBC. A laptop should be able to last an entire workday on battery. It makes a huge difference in convenience that you don't appreciate until you've tried it. My work laptop is mind bogglingly more powerful but also a bulky piece of shit with about 4 hours battery life. Got a used M1 macbook air that I code on during the weekends and it's fucking night and day I can pack a lunch work in the park while it's cool in the morning go to a cafe in the afternoon, don't need to charge once all day, not lugging around deadweight.

Are Thinkpad Nanos any good? I'm a med student and need something as light as possible with a good battery life while I clown around on the wards all day. Specs don't matter much - I'm using a 2017 Macbook Air and it's good enough for me, just dying.

I've had this idea for a while of a piece of software that aggregates Labor News from all of the world, and allows the user to sort them by country, type of news (labor strike, union busting, laws passed/repealed, settlements reached, cooperative formed, etc.) It would do this for each and every country and do this only for News platforms that are written from a pro-labor perspective (so you don't end up with a bunch of RadioFreeAsia type crap).

Is this a naive idea? I know people already use RSS feeds for this kind of thing but I'm thinking of something a little more specific.

This is a pretty good idea, might be willing to help some.
The tricky bit would probably be scraping (beautifulsoup etc.)
Many socialist news sites are not going to have an RSS feed.
You would probably also need volunteers to do tagging.

As an alternative you could have something like the main view of https://lobste.rs
But with a bot automatically collecting certain news articles, by scraping etc.
Once again with volunteers tagging them, or optionally even submitting stories.

This just got more real for /tech/
https://pluralistic.net/2025/04/27/some-animals/#are-more-equal-than-others

RSS and Atom feed if you only want per-country categorization, and each site is country-specific
I guess more granular organization would be even trickier, and obviously require DIY software
You would probably have to manually organize recent news articles according to the "news type"

If you actually wanted to make this the first step would be to gather pro-labor news sources to scrape. A minimal viable program would just scrape and output an RSS feed.

We all know there's mechanical, electromechanical, analog electronic, and digital electronic.

But what about about digital-mechanical?

Most people assume analog means only mechanical, and digital only means electronic.
But isn't there any form of media or machinery where it's purely mechanical but in a digital manner?

>digital-mechanical
It's called "relay logic" as an electrician I have had to work with it but luckily most of the time my clients have enough money I can convince them to replace it with PLCs.

Bio-digital?
Bioelectrical/Biomechanical = nervous system

many adding machines are purely mechanical and digital, including mechanical cash registers. Zuse's Z1 computer was also purely mechanical. I've seen papers about nanomechanical computers being a potentially fruitful approach to computing

Is Opera Chinese now?

>>28926
owned 71% by a chinese company,and the chairman also owns 10% and is part of that company.
the biggest problem is still that it's chromium based

>>28927
I mean I really wouldn't care if a chinese company bought the majority of, for example, Meta. Because It would still be Meta. The CCP doesn't oversee every decision a chinese company makes for overseas ventures, just has a spanking paddle ready if a line is crossed.

It is spyware for chinese companies who have no qualms about selling your data to western porky because to get rich is glorious.
