What’s New in C in 2023? 3 years ago

What's the opinion here on decimal floating point (_Decimal32/64/128)? I'm guessing there's a significant amount of business software using double for monetary amounts out there that could benefit this being standardized. I think it has been in gcc for over a decade as an extension though...

Color of text on monochrome terminals with green-on-black and amber-on-black? 4 years ago

I used info in this article when I made this VSCode-theme a couple of years ago: https://vscodethemes.com/e/krueger71.crt-themes/crt-amber?la...

I tried to coax all elements in VSCode to use only two colors (background and foreground) with the foreground in only a few different intensities. It might give a CRT-vibe to some.

The theme is due for an update since newer VSCode has elements that aren't styled correctly.

Apache NetBeans 15 4 years ago

Back in the day I thought Netbeans rocked! Instead of the Lego-like assembly of plugins in Eclipse you got something that worked right out of the box (we're talking a 10-15 years ago and focused on Java/JEE/JSF).

Japanese audio brand Onkyo files for bankruptcy 4 years ago

I had an Onkyo 5.1 system in service from 2002 - 2018. Great stuff! First movie I watched on the system with a 28" CRT TV was "Driven" on DVD. Going from TV-speakers to a full set of speakers including subwoofer was amazing! Later on it serviced Blu-ray:s and a PS4 beautifully.

Ask HN: Does anyone use a Raspberry Pi as your main computer? 4 years ago

I use a Raspberry Pi Zero 2 W as a cupsd print server. It is powered by usb from the Wi-Fi router and connected directly to an old USB laser printer nearby. Works great to print wirelessly.

I also have a Raspberry Pi 4 (8gb) with an Argon One M.2 case and a Kingston SSD. I use it mainly for coding/tinkering in C, Pharo, Racket etc. Not logged into any social media or mail in the web browser, just using it to read docs etc. Fast enough to be usable but no speed demon for sure. Overclocked to around 2GHz/64-bit OS.

Ask HN: What book(s) did you love reading this year? 5 years ago

Of the Tolkien books I've read, the LOTR-trilogy is a classic page turner. Once you get past Bilbo's birthday you can't really put the books down. The Hobbit has more of a children's tale-vibe, but still worth the read. The Silmarillion is harder and the first time it feels like you are cramming for some history exam, but I found that if you read it again you get more context and start untangling all the relationsships which gives a lot of extra character to the other books. The Children of Húrin can be found in abbreviated form inside The Silmarillion and is a dark and tragic tale, but really good in my opinion.

Fortunately Peter Jackson made a good job with the original LOTR-trilogy. You can be a fan of the movies and the books at the same time even though there are (probably necessary) differences between the formats.

Sir Clive Sinclair has died 5 years ago

Sad to hear this. I got a ZX in the mid-eighties. It was the 16k-model but my father upgraded it to 48k, I think it even involved some soldering.

One of my best friends also had one and we tinkered a lot, all by ourselves. To get stuff to load from copied cassettes on whatever tape deck or boom-box you had available was sometimes a very frustrating experience. We cleaned the tape heads with q-tips and alcohol, set the five-band eq to some previous good setting (marked with a pencil), then loaded, adjusted and retried. Typing in long listings from computer magazines, often failing and having to double check and re-type parts was quite common too.

We also learned the value of RTFM. The first game my friend had on a cassette had a fold in leaflet. We spent one evening not being able to load it using the instructions. The next evening a brilliant move was made, remove the leaflet from the cassette and read the remaining part on the hidden side :) Success!

These experiences definitely help remove any fear of tinkering with respect to computers and other digital equipment that I later on have noticed in others.

Digitize MiniDV Tapes with Linux 5 years ago

Did something similar on my Mac. Dongle for Thunderbolt 2 to Firewire and then got the raw .mov files via iMovie. De-interlacing and encoding with ffmpeg. For a raw file with a size of say 600 MB you can get down to something like 30 MB with h264, h265 can reduce this further to perhaps 15 MB. All of a sudden those old memories will be easy to keep and share :)

Lost in Thought: Psychological Risks of Meditation 5 years ago

The first variant of Zen-meditation is often to count your breathing from 1 to 10 repeatedly. Sounds easy enough, but the mind starts to wander pretty quickly. If you get lost in your counting you just start over on 1 again.

Teaching Compilers Backward 5 years ago

I remember back in the late 90's when I was studying Computer Science at Lund University, Sweden. They had a research focus in compilers and had their own Simula-compiler if I remember correctly. When they taught compilers, students first had to take the low level programming course where you needed to build a compiler back-end for an in-house IL. The first compiler course you could take after that was very focused on the practical aspects of building a front-end for the back-end you already had. Theory was pretty minimalistic at this point if I remember correctly. You got the hang of basic operator precendence parsing with a recommendation to use if for the expressions in our toy language and recursive decent for the rest. Of course this was almost like throwing someone at the deep end of the pool and se what happens. A grueling course that was renowned by students to be one of the more work intensive in the whole curriculum at that time. A lot of late nights in the computer lab for sure.

Afterwards, when I had the second more theoretical compiler course, I did feel that all that practical hard work to make a fully functioning compiler with mostly elbow grease gave an appreciation of the theoretical constructs that could make this more tractable.

GCC 10.1 Is Out 6 years ago

Extended characters in identifiers may now be specified directly in the input encoding (UTF-8, by default), in addition to the UCN syntax (\uNNNN or \UNNNNNNNN) that is already supported:

    static const int π = 3;
    int get_naïve_pi() {
        return π;
    }
I see large potential for the IOCCC

Ask HN: How long do you think the quarantine measures will last per country? 6 years ago

As individuals we need some reliable way to know if we are immune and not contagious. We probably also need some way to prove this to others. People who have this status should be able to operate normally together with others and keep things running during a long lock-down. It wouldn't make sense to keep people locked inside if they can't catch or transmit the disease.
