fjfaase··on My AI skeptic friends are all nuts
When I ask chatGTP to generate the code for a M4F MCU that implements the VirtIO code for accessing the GPIO through RPMSG using FreeRTOS it produces two answers that are both incomplete and incorrect.
fjfaase··on Saw a guy coding today. No cursor. No windsurf. Just typing. Like a psychopath
Anybody show me AI generated code for a M4F implementing the Virtio protocol using RPMsg for GPIO. Preferable for FreeRTOS.
fjfaase··on I was wrong. CRDTs are the future – Joseph Gentle
Discussed before https://news.ycombinator.com/item?id=24617542#24621238 as mentioned in the article.
fjfaase··on Euro execs mull use of US clouds
Are you being satirical using a Google email address? You do not have your own EU based domain with an EU email address?
fjfaase··on Show HN: I built a tool to review my teammates' pull requests faster
Code reviews take a lot of time and delay intergration. As an alternative, you could do away with them to just do all commits on a single branch. That is the ultimate form of Continuous Intergration. As a developer you can do work on your own 'private' branch before merging to the main branch and having a tool to review your own code changes would be usefull.
fjfaase··on US halts student visa appointments and plans expanded social media vetting
Another step in limiting free speech and limit international travel. The EU might start to require visas for USA citizens. Currently it is not required for stays shorter than 90 days in a 180 day period (if I am not mistaken).
fjfaase··on Is Saying "I'm Leaving to Do What I Love" a Good Reason to Quit?
I am in the position that I could survive until retirement without having to work. Some five years ago, I decided that I would only work, if work was making me happy.

Last year, I was jobless for about half a year and I discovered that I found it hard to work on things I loved. Even when I had all the time to work on thing I loved, I still found myself procrastinating a lot. I had a hard time finding a new job and almost had given up finding a new job, concluding that due to my age I no longer was attractive for employers to be hired. Luckily, I did find a new job after some months.

I am strongly motivated when I can help others. For me it is important that I feel that my contribution has some added value. In my previous job that worked for the first years, but the last year, the organization forced me to work in a way that decreased my effectiveness and gave me a negative review due to this. While I had the feeling that I made a lot of efforts to deal with and help others as much as possible, I still got a negative review due some of my stance with respect to one project, which did not have the highest priority. After some struggles and realizing that I did not enjoy my work anymore, I decided to quit also because I felt I was on the brink of a burn-out.

fjfaase··on China approves national 'online number' ID scheme
In the Netherlands we have DigiD [1] for accessing all government services including organization that by law are allowed to use the BSN (a national identification number) [2], such as care institution, educational institution and pension fund websites. Financial institutions are also required to register the BSN with each private held account.

fjfaase··on Ask HN: Where do hackers meet in London?
Or have a look at hackspace.org.uk for some more options. Even if you do not want to join one of these, you might find people to direct you in the right direction. Most hack(er)spaces have open evening on Tuesdays.
fjfaase··on Ask HN: Where do hackers meet in London?
Did you try London Hackspace?
fjfaase··on Forget voting – it's time to start choosing our leaders by lottery (2014)
Americans on average are just to stupid for keeping democracy and are allowing their country to become an authorian state, just like it happened in Russia.
fjfaase··on Flix: an effect-oriented, functional, imperative, and logic programming language
Is this a high-level or a low-level programming language? What does it offer? When i is a 32 bit integer, than i + 1 is not an increment operation, as it can result in a value that is much lower than its input.
fjfaase··on Definitive solution to the hardest problem in computing: P = NP?
I have no idea if the proof is correct or not, but my first impression is that it does not sound bogus, like so many other attempts.
fjfaase··on Mathematician solves algebra's oldest problem using intriguing number sequences
Floating numbers with a fixed precision based on a fixed base, are really limited on what rational numbers can be represented. For example, the standard floating point formats cannot exactly represent the fraction 1/3. One would expect that 3 times 1/3 would result in 1, but it does not. This is based on an implementation decision on how to represent rational numbers. There are computer algebraic systems that represent fractions like 1/3 exactly, such that 1 times 1/3 is equal to 1. In a similar way it is possible to represent certain real numbers like the square root of 2, such that the square of such a number is exactly equal to 2. To being able to print such a number in a certain base (10 for example) does not mean it is not possible to represent such numbers in a way that it is possible to perform calculations with these.

One should realize that the implementation choice to represent floating numbers in the way it is done in processors is related to performance and memory usage.

fjfaase··on Mathematician solves algebra's oldest problem using intriguing number sequences
This has been discussed before. I understand that it is not a new result and also not an exact result: A method for constructing an infinite sequence of approximations to the exact solution. It has been long proven that exact solutions do not exist above a certain degree.
fjfaase··on Spade Hardware Description Language
I thought that this was about the hardware description language Clash developed by some ex-colleagues, but it appeared to be something else. Clash [1] is based on the functional programming language Haskell and it can output to VHDL, Verilog, or SystemVerilog.

Although the last official release mentioned on the website is from 2021, it is still actively developed on GitHub [2]. See also contranomy [3] for a non-pipelined RV32I RISC-V core written in Clash.

fjfaase··on June Huh dropped out to become a poet, now he’s won a Fields Medal (2022)
I wonder if somebody already has scanned the OEIS for all recurrent relations that are "log concave". These are mentioned on https://oeis.org/wiki/Index_to_OEIS:_Section_Rec . just scanning the page, I guess there are not so many that are unimodal and log concave.
fjfaase··on June Huh dropped out to become a poet, now he’s won a Fields Medal (2022)
I wonder if the recurrence equations for the number of spanning trees in the GxP_n graphs also meet the log recuirement.
fjfaase··on Ask HN: How have you spent time outside work for the past couple of weeks?
Social media, YouTube, TV, visiting exhibitions, maintaining website, developing a C compiler for compiling TCC (https://github.com/FransFaase/MES-replacement), walking/biking.
fjfaase··on How GitHub engineers learn new codebases
Good advice! Good also be used as a metric for healthy development teams.
fjfaase··on Erdős Number
I now regret that I did not ask one of my teachers to be a co-author for the only math paper I got published, which was a broad generalisation of a technical report he wrote. This was long before I knew about the Erdős number and that he had one. I did show him the paper for review and he gave me some comments about some particular case.
fjfaase··on The language brain matters more for learning programming than the math brain
I did not read any mentioning of testing non-verbal IQ. Many math skills also depend on verbal IQ. Verbal IQ correlates strongly with academic performance and probably also with learning new programming languages. I personally have a much stronger non-verbal IQ than a verbal IQ. Often when I think about algorithms, it is all about abstract blocks moving around even before I have written a single line of code. I usually see multiple solutions in my head and often find myself being stuck because I cannot make a choice. I always takes some effort to code the solutions and weed out stupid bugs due to spelling errors mixing up varisbles, but then things work correctly.
fjfaase··on Just redesigned my personal site with a TTY-style interface
Maybe turn it into an adventure game. I recently though about making an adventure game about my house and the surroundings.
fjfaase··on Chinese researchers make EUV breakthrough
If I understand it correctly they achieved a conversion efficiency of 3.42% for a less efficient technique that is not used by ASML for producing EUV. Seems it is more like making progress than a breakthrough. A good light source is essential, but building a machine comparable with the ASML machines requires a lot of engineering in other areas as well.
fjfaase··on Tiny Emulators
I do not know if you can run games on these online emulators, but there are multiple emulators that can run games. Just do a little internet searching. I quickly found Atomulator.
fjfaase··on Tiny Emulators
Nice to see the Acorn Atom, one of the first computers I wrote software for and also the first I wrote an emulater for under Solaris using X11 in the nineties.
fjfaase··on Trump says China tariffs will drop 'substantially – but it won't be zero'
I wonder if China will drop its restrictions, such as on the export of rare metals, even if he would lower the tarrifs to zero.
fjfaase··on Ask HN: Are you finding it harder to enter the US in the last couple of months?
And what about the two young German girls that were strip searched in a detetion center because there was not return flight the same day? They were rejected entry because they had not booked accomendations for every night being back packers going on a world trip.
fjfaase··on I want to work for an entrepreneur who has awakened spiritually
The qualities of a spiritual software engineers does not lay in the relationship with the code, but in the relationship with fellow developers. To be enlighted means being able to live in a world where most people, including bosses, are not or less enlighted. Enlightment is not a state once achieved, but a life long struggle with as much lows as highs. Enlightment is a very personal process, which is different for everyone, but escaping hard conditions, might not be the best road to choose.
fjfaase··on US judge finds administration wilfully defied court order in deportation flights
No, it is not small. I am really surprised that no one has been arrested yet who has been involved with this kipnapping of people. If Donald Trump is sanctioning this kipnapping, he is involved as well and should be arrested as well. That he has not been arrested yet, shows that he is above the law.
