i kind of hate that OjectiveC killed ObjectPascal and that we don't have a mainstream modern kernel written in Pascal.

it can show a basic unbloated news site from my contry

it can show lwn.net

it can show HN

it can show old popular local forum

it can show rss feeds

it automatically blocks (does not work on) all the popular social networks

what else is there?

there's perefectly working stuff from php from over 20 years ago that only had to keep up with security patches

apparently a lot of hardware is still not properly supported, like speakers, microphones and energy saving

Sounds like headers in general are not necessarily a good idea.

They provide flexibility but at a cost.

I enjoyed Borland Pascal compilation speeds and clean dependencies before switching to Linux. I miss it, together with Delphi.

If there was only a good Ruby in browser implementation, I'd be more than happy to go Ruby everywhere.

New Rails with turbo streams is great, but often times it's desirable to do data processing on the client, and then getting back to JS feels like a step down.

I was under the impression that a lot of the original team was hired by MS and that was the end of Borland that created Delphi.

Still Delphi was better.

- DSL for UI (Forms) - fast native compiler that produced self sufficient binaries - great component library and many open source libraries - Object Pascal was extended to fit perfectly the needs of UI programming

Hetzner is super affordable alternative to AWS, now with a DC in US, east coast.

I have pms3003 you can get for about 12 USD on AliExpress.

I bought a small usb-to-serial adapter connected to Raspberry Pi Zero W.

Here's a combo with a similar device here:

There are plenty of comparisons available online, but there's a good overview site here: https://aqicn.org/sensor/

It's good that the banks can be bailed out. It's good there's some inflation. It saves capitalism from itself (the rich acummulating all or practically all the coins).

Chrome does this for a long time now and I don't consider it an issue. You see a frozen version of the last decoded keyframe until the next one is decoded. Elegant solution IMO.

It might not be perfect, but allowing only web workers (if you agree on getting push notifications from a page) might be the solution.

If you don't run untrusted code you should be fine on bare metal servers too.

> As someone who is working with X11, I strongly disagree. It really needs replacing badly. It doesn't even work; only a few code paths even get tested on for example GLX, which is why complex X11 apps like browsers need blacklists.

Blacklists are needed because OpenGL drivers for specific hardware have bugs and can have missing functionality. Those can affect Wayland too, since the same drivers are used.

Modern Xorg supports direct rendering well, Keith Packard authored a lot of modernized infrastructure such as DRI2/DRI3, and even support for VR (work he's been doing for Valve).

There's also the important VK_display_timing extension implementation he's done with Croateams Alen Ladavac:

https://twvideo01.ubm-us.net/o1/vault/gdc2018/presentations/... on Xorg

Sadly, I don't see much more recent activity from him or Alen about these topics, but it shows that Xorg is still the main platform of inovation for Linux real-time graphics needs.

You must be doing something wrong. There's a lot of overhead for frameworks like Symfony, yes. But it's possible to write reasonably productive and modern website code where you can get sub 20ms responses (doing auth, fetching from db, processing and rendering html). I know because I've done that, on PHP 5.4.

Smartwarches have body temperature sensors now? Which ones are okay to buy?

A mid sized web site with 5000RPM would be 219 million of requests per month: so 766 USD/month just for API GW, without data transfer, lambda, static/cdn or DB costs.

Most of these articles I read about AWS Lambda (they rarely mention API Gatweway because it's expensive) sound like paid marketing.

I've seen just API Gateway costing more than entire infrastructure costs of similarly sized websites.

If you can properly saturate EC2 it will be significantly less expensive than Lambda but with lambda you have to pay API GW and the vendor lock-in price.

I've started flagging these submissions.

Do you have a public example that illustrates how PHP/Hack code in Facebook looks like?

My problem with PHP is that most of modern frameworks seem to take a lot from Java, and people have started to use type hinting whenever they can, so the code looks like (uglier) Java, but without advantages of performance (being made worse by having to setup everything on every request) or compile time type safety.

I've improved this comment a bit over here:

http://vrodic.blogspot.hr/2017/07/my-thoughts-on-php.html

Unless you are using ReactPHP it's not really for real time apps.

It's weird for me. I used to write both Java and PHP in the past.

Custom PHP framework we built took into account the way PHP is executed: you are stateless and need to setup everything on every request (runtime is fast to start with FPM and opcode cache). Namespaces based cheap autoloader worked great. No composer. We used singletons for getting the configuration and connections to DBs. There was almost no setup code that needed to be run every time other than loading .ini based configuration and connecting to the DB. Our webapp responded under 20ms (DB and Sphinx included), and I could get it to respond in 1 ms for things where we needed to be quick and didn't have to output HTML with Forms. I was really small and you could read the whole framework code in 1-2 hours. It worked with SQL in a reasonable way. You didn't have to write your SQL for simple CRUD, but for larger things involving joining multiple tables and more complex expressions we wrote native SQL.

I switched jobs, and started with Symfony 3. The thing felt like some Java framework, but poorly documented and harder to use than it should be. It had lots and lots of setup code done before handling every request. There's a whole DI framework with it's own tons of setup code for every component. And you have to do setup even though you don't use the component in that particular request. There's ways of doing lazy setup, but you still waste time to wire that up. Framework overhead can be 30-100ms. Other modern PHP frameworks have similar overhead. I know that there's PHP-PM, to save some of that work that isn't really $_REQUEST specific.

Everybody is using type hints wherever they can, and it feels as verbose as Java, but without compile time type safety, and you can't really put type information everywhere (class members for example). Even though PHP runtime has made great progress (it's probably the fastest interpreted language, and it's great it has reference counted garbage collection), it feels like language is struggling to find it's identity, with it taking a lot from Java and still coping with ugly legacy ($, having to use $this inside a class function, php.ini, features for supporting templating even though it's rarely used as a templating lang in modern frameworks).

Doctrine and it's verbosity feels very ugly to me.

Learning Python and Flask (as an example) was much more enjoyable than switching from a nimble custom PHP framework to Symfony.

I'd argue you can write fast, simple and maintainable PHP, using state PHP runtime has setup for you ($_POST, $_GET, $_SERVER etc), namespaces and a namespace based autoloader, trying to use pure functions when you can (using static classes shouldn't be a sin - just to split your code in sensible parts), and using general good practices for writing readable and maintainable code (avoid long functions, huge classes, too much block nesting, decoupling, naming things in a good way). With some conventions you can write a decent and productive framework quickly, but you could do that with a nicer language too, so what's the point?

Kodi struggles with H265/FHD on Rpi2, but I'm hopeful this one will make it.

Any other suggestions on hackable and cheap H265 capable machines?

It's strange that no 28W Broadwell-U machines have been reviewed yet.

Since they have almost 2x of the power budget than the 15W ones, I expect them to be a whole different beasts for loads where you need both GPU and CPU to be active.

Probably AMD, they fund open source driver development and release good documentation for their GPUs.

Intel is ok too, but their hardware is not really targeted for gamers.

That being said, if you are fine with using proprietary drivers, currently nothing beats nVidia in terms of performance, features and stability of OpenGl drivers.

You would be supporting the ecosystem with any purchase, but if you are politically inclined on free software then the choice is AMD or Intel.

I'm not conviced this will help that much for Intel GPUs. Developers from Intel have been optimizing shader compilers specifically for Dota 2 for some time without much impact on performance.

Dota 2 is probably memory bandwidth limited on Intel/Linux/OpenGL and that is likely the case for other games too.

So maybe modifying the OpenGL part of the game engine a bit to take memory bandwidth constraints of Intel GPUs into account would help more.

When I was looking into the issue of Intel GPU peformance on Linux many months ago there were no tools to profile memory bandwidth bottlenecks.

Hopefully they'll use it to make Dota 2 for Linux comparable to Dota 2 for Windows :)

Right now it doesn't perform well at all (using 2x more memory and being significantly slower on Intel GPUs) , and still comes with an annoying sound bug (https://github.com/ValveSoftware/Dota-2/issues/770)

In addition to what zurn said, they also don't specify the exact Core i3 model number (it could be an older generation), the RAM speed, and if the data set fits in cache.

If RAM access is needed ARM machines usually fall behind quickly, since they usually have much lower RAM bandwidth.
