2023 will be for AI training data what 1950 was for carbon dating.

@theNRO @AFRINIC @apnic @TeamARIN @lacnic @ripencc @ICANN Exactly the exciting read I hoped it to be. Well done everyone involved.

Imagine playing chess against a distracted and not particularly gifted 5 year old. On a monopoly board. And he's just found a rock in his pocket that is now on the board as a "super king turbo".

HTML might be getting a new type of tag, which… hasn't happened this millennium! It looks like this: <?marker name="…"> See the video in the next post for a quick intro to how it works.

@esrtweet Chaperoned development is how I'm trying to approach it. Gets pretty intense and the models aren't built for that kind of interaction really.

We only have one term for the evolving mode of writing software cooperatively with an AI - "vibecoding". I think we need at least one more term, because there's a spectrum of techniques being explored and "vibecoding" can describe at most one end of it. At one end of the spectrum is what I think of as YOLO coding, and I'm tempted to compound-word it as "yolocoding". That's where you describe an application that you want and just tell the computer to grind on your informal description until it thinks it's done. I never do this. I hear stories about people doing this ("I wrote an entire videogame in 3 days!") and getting good results. I'm not sure I believe them. I inhabit the other end of the spectrum, where you ride the AI like a fine warhorse. You start by tossing an informal spec at it, then you and the computer iterate on both the spec and the code. It does the moving and supplies the grunt, you do the steering. I'm not sure what to call this. "Symbocoding", maybe. You and the AI are symbiotic, more than the sum of the parts. I think when people talk about "vibecoding" they usually mean something more towards the yolocoding end of the spectrum. I don't think that's where you'll get high-quality code from, and where the big productivity gains are. I could be wrong, but whether I'm right or wrong I think we at least need to be able to articulate the difference between fire-and-forget and a highly interactive, carefully directed approach. Yolocoding. Symbocoding. Are these the right words? I don't know, but I'm sure the distinction is important.

@zuhaitz_dev Fetching individual bits sucks so mostly doesn't happen. But if you take an 8 bit character and just look at the last bit of that character, 0,n and N map to False and 1,y and Y map to True 🙂

What is better, 8 booleans in 8 bytes or 8 booleans in 8 bits. It is not as easy as just choosing one. The first one is simpler in terms of CPU instructions, as having only 1 byte for 8 booleans will require shifts and masks, but the ALU is not the bottleneck, memory is. In the first scenario it would need to fetch x8 bits of data from the memory. Which, for 8 booleans is not much, but for a large array (like a boolean flag for each pixel in an image) it will fill the L1, L2 and L3 caches a lot faster. A cache miss is a lot more painful than an extra AND/SHIFT. It also depends on how we access the data. For looping, bit-packing will be the best as there's more data packed, reducing cache misses again. If it's for random access, a byte array surely wins (if the data set is small enough to fit). I must also say that with bit-packing we can find race conditions as we cannot access bits atomically. It is important to consider everything. But at the end of the day, if you don't worry about performance, use a byte array.

@brankopetric00 The correct answer is, as usual, it depends. What's the amount of time that passed between the requests, what's the DNS reply TTL, how long is the keep alive timeout, did your host have any other traffic for the default gateway, ...

Senior DevOps Interview: What happens when you type google[.]com into your browser and hit Enter? Focus specifically on the TCP/IP stack. 1. ARP request (to find the gateway MAC). 2. DNS (UDP). 3. TCP 3-Way Handshake (SYN, SYN-ACK, ACK). 4. TLS Handshake. 5. HTTP GET. Which of these steps is skipped if you visit the site a second time (Keep-Alive)?

@robertgraham In civil engineering, pi=10. Saves on the math and builds in a safety margin.

The correct value of pi 𝜋 is 3.141592653589793. It's the maximum precision for a 64-bit (double) floating point number according to the IEEE 754 standard, used by NASA and rocket engineers for all their calculations for rockets in the solar system. You'll never practically need greater precision, and you'll rarely do floating point at less than 64-bits, so there's little point to use fewer or more digits. Now, gamers might choose 3.1415927 for 32-bit floating point, but they understand the compromise. For everyone else, pi 𝜋 is exactly 3.141592653589793.

@NJHoekman @jvantill @POL_Amsterdam Je kon niet eens zelf de moeite nemen om er iets over te tiepen en liet dat aan een AI over. Broodje aap.

Als Epstein-bestanden voldoende zijn om zonder bevel servers te confisqueren, zijn we iets fundamenteels kwijt. De Nederlandse politie heeft zonder gerechtelijk bevel een server van VPN-aanbieder Windscribe in beslag genomen. Dat bevestigt het bedrijf zelf. Volgens de autoriteiten wordt de server teruggegeven nadat deze “volledig is geanalyseerd”. Windscribe noemt de actie uitzonderlijk en zorgwekkend, en terecht. Waarom dit zo problematisch is: - Inbeslagname van digitale infrastructuur hoort aan strikte wettelijke voorwaarden gebonden te zijn - VPN-providers bestaan bij de gratie van privacy en vertrouwen - Er was geen rechterlijke toets vooraf - Op de server bevonden zich naar verluidt ongelakte Epstein-bestanden, wat onvermijdelijk vragen oproept over motieven en proportionaliteit Dit gaat over rechtsstatelijkheid, digitale privacy en de vraag hoe ver autoriteiten mogen gaan “voor onderzoek”. Als we accepteren dat servers zonder bevel kunnen worden meegenomen, analyse eerst, juridische onderbouwing later. Dan zetten we een gevaarlijk precedent. Zeker in een tijd waarin encryptie, privacy en digitale autonomie al onder druk staan. Transparantie en rechtsbescherming zijn geen luxe. Ze zijn de fundering van vertrouwen in de overheid.

@cryptoron None of that post makes sense. Unlike some other countries, we still have a mostly solid form of due process in place, and none of this is in line with standard operating procedures of the Dutch high tech crime unit. They're way smarter than this.

The Dutch police are not known to seize equipment like this without proper legal authorization. Also, in digital forensics it is standard practice to keep a seized server powered on or otherwise technically accessible until investigators can perform a live memory (RAM) capture in a forensic lab

@dvmikun Remember, everything's a database if you hold it wrong.

@IceSolst In vi, hjkl for left, down, up and right 🙂

Help my arrow keys are gone and it has one-shotted me, idk how to use terminal or edit text anymore Do not get a mini keyboard

@cryptoron Herinnert me er aan dat ik ergens in de jaren 90 Venezuela offline heb gehaald door op IRC "+++ATH0' te sturen.

@SwiftOnSecurity "Be liberal in what you accept, and conservative in what you send" - Postel's law on protocol design. Society could certainly use a bit more TCP/IP.

TCP/IP is a social construct

@withzombies Meanwhile some of the largest companies on the planet officially require people to take vacation days to attend work related conferences, and pay attendance and travel out of their own pockets. So yes, many of us are managers but the mindset issue is elsewhere.

@rvmNL Many of us are managers who can advocate for policy changes

I wish people would stop putting their conferences on weekends. We're a grown up industry that makes money. We need to start acknowledging that attending conferences is valuable work time.

@benrobertskenya @MediaBtw @NRSTeam_ I'm shocked. Shocked.

Is this possible proof that Blue Tech Wave Media @MediaBtw and @NRSTeam_ are the same organisation? They are sending out near identical emails to African IP Address resource holders in Africa at the same time ?

@DrPeering @ripencc @RIPE_Atlas Proby Mc";DROP TABLE;

A fun update of the RIPE Atlas Terms & Conditions from @ripencc & @RIPE_Atlas soon. Turns out folks were using “inappropriate” names (and they don’t mean Proby McProbeface) for probes! What would your inappropriately #RIPEAtlas probe name be? Inappropriate answers only please.

@DilanYesilgoz Hee kijk, er komen verkiezingen en ineens is er weer gratis geld.

De VVD kiest voor rust in jouw portemonnee. In plaats van o.a. tanken en je hypotheek nóg duurder maken. ✅ Zuinige overheid ✅ Lagere accijns ✅ Hypotheekrenteaftrek behouden ✅ Lagere lasten op o.a. energie en inkomen ❌ Geen hogere lasten op spaargeld en erfenissen
