karambahh··on Training a 4B model to produce 81% faster query plans than Postgres
I'm also quite skeptical of performance/determinism over a real world load but if I'm not mistaken, a 10 000 qps with large shape of queries would not benefit much either from genetic algos, would it?
karambahh··on Show HN: TickClip – An AI shopping agent that can recommend not buying
Your website claims not to carry affiliate tags but /verdict/ definitely does so your FAQ claims seem false.

Some prices are shown as "0$" which is obviously a bug.

Seems to me that your decision model is basically "look at camelcamelcamel's slope for the item", which is a decent idea (I do this myself).

karambahh··on Show HN: I'm a 15 Year Old Wannabe Engineer, This Is a Cycloidal Gearbox I Built
It's a protected title in several european countries but I've never seen enforced, despite myself being part of an officially sanctionned body of engineers.

Afaik claiming to have an MD (for obvious reasons) or a PhD would land you in hot water much, much faster, despite technically being exactly the same "offense"

karambahh··on How A Gang of Thieves Pulled Off a Multimillion-Dollar Data Center Heist
As noted by others, it is indeed a book promotion [1] The "petty criminal" has himself published a series of books [2]

However I take issue with your argument with "hacking would have been easier". DCs in the 2000s were (and to a large extent, still are) extremely easy to access. If the data at stake were actual "banking" data, in the 00s, it could have been still largely "air-gapped" (in the loose sense) from the internet. Hacking would have required a lot of lateral movement. And experts.

Hence, a large trail. Arguably larger than "hey bobby, here's a wad of cash, go in that building, steal these boxes in corridor A"

I also take issue with the "physical locations of DCs are still secrets" angle of the article.

Anyone working in a DC-adjacent industry and is curious enough can locate the back-entrance to any DC they have some business with. If it is a secret, it's not a well kept one (for good, operational reasons!)

Sites like DC Map give you the exact physical location, for instance.

The story is entertaining but it has clearly been romanticized.

karambahh··on Europe's company websites are mostly served by US vendors
I think this is exactly the market Mollie is tapping in at the moment: "as feature complete as Ayden, but no need to run millions by us to be a first class citizen"
karambahh··on Europe's company websites are mostly served by US vendors
Funilly enough, payment might be the area where it's the easiest to find a credible european alternative. Adyen is an enormous PSP Mollie is aiming at smaller companies.

Scaleway, OVH, Hetzner, Infomaniak and others do have pre-packaged, managed services, but you might not find "eveything and anything" that you find at, say, AWS. The other side of the same coin is that you're as vendor-locked if you buid something with one component at SCW, one at Hetzner and the third at Infomaniak... (but you have to manage 3 different invoices...)

karambahh··on Europe's company websites are mostly served by US vendors
This tries to capture Europe as a single coherent market, which it is not and by far.

It's comparing countries with vastly different socio-economical landscapes and sizes.

Is "using Cloudflare as a CDN but hosting everything at, say, Hetzner using generic systems/opensource components" the same as "having built a complete ecosystem with Amazon specific software"?

Getting out of the walled garden of AWS, GCP or Azure is notoriously difficult. Some european cloud providers made this one of their key selling point, advocating for openess and "multicloud". This had, to my knowledge, next to no effect.

Vendor lockin is real. Dependency to a vendor located outside of your generic law system is, indeed, a risk. But this article probably isn't the way to measure it (and it's a tough job to do)

karambahh··on Long Wave radio era set to end with switch-off
For other readers, please be aware that only BBC World & BBC Radio 4 can be streamed outside of the UK.

For about a year now, BBC has been aggressively geoblocking other radios.

karambahh··on US private credit defaults hit record 9.2% in 2025, Fitch says
I've been told by the head of compliance of the largest European banking group that 2.5% is exactly the threshold at which they begin to be very worried/ at systemic risk

Apparently they operate on very low level of tolerable risk (way lower than I thought)

karambahh··on Sizing chaos
Definition of "high status" vary by demographics.

Some want to carry X sportswear with prominent branding, others take pride in high-price tag items without any explicit branding.

The "I identify with this athlete", "I identify with this musician", "I dgaf what you think of me" groups probably don't intersect much, with brands and offering catering to these and multiple others...?

karambahh··on European Tech Alternatives
Feels like you're addressing two different topics in one comment.

Legally speaking, a one person company can address the whole EEA market. From a marketing/sales standpoint yeah, sure, it's probably hard to address culturally different markets like Portugal, Poland and Sweden.

But it does not have much to do with regulations, especially not ones decided at the EU level.

I'm all for better integration but diverse cultures are here to stay....

Sample size of one, but done business in Italy, Spain, Belgium, France, Switzerland and Germany: main issues were not regulation related...

karambahh··on I sell onions on the Internet (2019)
Except that lemons are picked for "cheap" in Argentina (and oranges in Morrocco or Valencia), industrially packaged to ports (most likely to BCN or VLC ports) and then shipped in containers to Palma.

Pick the oranges in the middle of the island: not cheap, as stated. Squeeze & freeze the juice (likely around Palma): not cheap, not even including transportation. Ship them back to the continent: probably not cheap either.

Transshipment is extremely costly and even more so at a smaller scale, and that's what we're comtemplating here.

karambahh··on I sell onions on the Internet (2019)
Mallorca is a mountainous island in the middle of the med. Exporting something from Mallorca seems like a logistical challenge to me. Exporting something refrigerated or frozen, even more so...

Maybe store-shelf product such as gummies or something?

Fresh juice takes 2kg of oranges per ~1l/~1kg. Plus electricity and handling costs...

Still, you'll need a large multiplier on the transformation process: organic EU orange are 1.7€/kg, standard are 1€ wholesale market price (meaning its origin is continental spain or italy I guess). Frozen orange juice is 3.93€ (Brazil)

karambahh··on French ex-president Sarkozy begins jail sentence
He has half a dozen court dates set for other stuff related to corruption/money/....

Assuming he's losing the appeal on this particular case, he will have been sentenced for scheming with a convicted murderer (Lockerbie amongst other things).

If convicted, that person will be guilty of criminal actions together with a foreign dictator and his terrorist in chief.

Not exactly stealing gums.

The case is of particular seriousness and he's a convicted person, repeat offender.

Would something as serious be put under the rug in other democracies? I'm not so sure. If Justin Trudeau is found accepting money from a bunch of Taliban involved in weapons trafficking, would the RCMP turn a blind eye?

(Why do I say "if convicted"? He appealed, so he is innocent until proven guilty. Why is he in jail? In large parts because his political party lobbied for this type of sentences. Leopards did eat his face)

karambahh··on French ex-president Sarkozy begins jail sentence
Why would "elected" status grant you immunity?

Say someone is legally elected president of France. They serve their 5 years term, doing their job. They get out of Elysée Palace, draw a gun and shoot a passer by. Do they get a free pass? Wouldn't that victim deserve justice?

That person, not a divine being, a mere mortal like the rest of us, has been convicted of serious offences. He is now serving his sentence as any other person would (well, not exactly, for instance he gets a clean solo room and 24/7 security detail).

If your point is "an elected head of state should not be prosecuted by a standard court of justice" (a point I still disagree with btw), the french judicial system got that covered with "cour de justice de la république".

For offenses committed while doing their jobs. Use your elected position as president to steal money? Cour de justice de la république it is. Not a walk in the park, judges & a "jury" of members of the Parliament. Aggravating circumstances (committing an offense while in an official capacity) means theoritically harsher sentences.

What he's been convicted for was as a private citizen. Standard judicial system. As should be, nothing naïve about this.

(Huge simplification of the french judicial system, the actual nature of his current legal status, etc as this case is utterly complex. Judge's ruling is over 400 pages long, and he's appealing, and he'll mostly spend a month in the lam and the rest under house arrest)

karambahh··on Greg Newby, CEO of Project Gutenberg Literary Archive Foundation, has died
Met him at HAL 2001, volunteered together a bit there. I think he was heading the speakers herald team I was part of. First encounter with the hacker conference scene, he guided me wisely.

Patient and kind indeed.

He's the reason I kept going around European hacking / free software events. I owe him cultural discoveries, long lasting friendships and tech partnerships. Very saddened by this news.

So far the thread is full of similar interactions with him.

That person changed so many lives, by his contributions to culture and technology but more importantly (?) because he had tremendous impacts on the lives of many people he took time to interact with.

I know that these threads are always full of "this recently deceased people made the world a better place". I lived with him 4 days 24 years ago so I can't say I knew him...but I know I wouldn't be writing this about more "famous" people I interacted with.

So long, and thanks for all the fish.

karambahh··on RFC 3339 vs. ISO 8601
Others point out missing tz.

It's also not that "user friendly": depending on their locale, users will usually expect for instance DD/MM/YYYY. Sorting by YYYY-MM-DD won't feel natural to them.

karambahh··on Show HN: AI Phone Interviewer – get a call in 30 seconds
I'm working in this space, reach out to me and we'll talk. Entering the EU market with this is going to be extremely touchy, the privacy protection agencies are going to mow down your clients with fines if you're not _very_ careful....
karambahh··on Twake – open-source Google Workspace alternative
This tool is made by the french OSS company Linagora, active in that space for more than 20 years.

They mostly likely have thousands of users running on corporate or state platforms so it's not a "one off project" supported by a couple individuals, it's an actual stack with probably a large dev team.

However, Linagora has been entangled in a legal battle for 10 years with former employees that founded BlueMind[0], a competing offer. Latest episode in the saga appears to be "back to square one" with the legal case coming back to a fresh start based on complex legal issues [1]

karambahh··on Show HN: A toy version of Wireshark (student project)
Yeah, and especially as Vanta is adjacent... I think a rebranding is in order.

Vanta (and the auditors they market) is a nice company I'm happy user of but I'm afraid they won't be too pleased with this.

Your project is a pretty nice overview of what network level monitoring encompasses, I'd say it's more than a tool, it has obvious educational value. Would be sad to see it buried under naming issues.

karambahh··on Why does Debian change software?
I'm on the market for a decent laptop. Don't want to side-line the thread, but is Arch supported decently on, say, Dell or any "enterprise grade" laptops?
karambahh··on Is 7 days a week the new norm (for YC)?
As mentionned elsewhere, 30h of being "in the zone" is already above average.

Above that, the teams will be present, or rather their bodies will be, but non productive.

Death march is a real thing and it results, as the name implies, in death.

As a manager, if you choose to run your team in death march mode, then it implies reaching your goal is more important than the well-being of your team and the ability to function long-term. Short term is... short term.

karambahh··on CrowdStrike Update: Windows Bluescreen and Boot Loops
AWS East going down will (and has) cause(d) disruption in other regions. Last time it happened (maybe like 18 months ago), you ran into billing and quota issues, if my memory serves.

AWS is, as any company, centralized in a way or another.

Want to be sure you won't be impacted by AWS East going down, even if you run in another region? Well, better be prepared to run (or have a DRP) on another cloud provider then...

The cost of running your workload on two different CSP is quite high, especially if your teams have been convinced to use AWS-specific technologies. You need to first get your software stack provider agnostic and then manage the two platform in sync from a technical and contract perspective, which is not always easy...

karambahh··on The future of logistics is in the neighbourhood
That sounds nice in theory but how do they solve inventory split?

Inventory levels for SKUs across multiple warehouses is notoriously difficult to balance, even more so for smaller (Shopify mom&pop) retailers.

If I split my inventory across multiple packers, the likelihood to get "local-ish" delivery is getting smaller and and smaller.

What I get, however, is a scalable workforce for packaging/shipping. It can result in economies of scale if and only if all the order can be shipped from a single packer.

By the way, if they use anything else than ultra local carriers, the package will anyway be sent away to a sorting center dozens or hundreds of kilometers away from the packet, if even the customer is right next door.

It's a good idea if you want to "uberize"/get a scalable packaging/inventory workforce, but it seems to me to be disguised under a green-ish marketing varnish that quickly fades away once you look at it closely.

karambahh··on There’s a 30-year old dead Rabbit in Seven Sisters tube station
France Telecom bought Orange (then a UK company) and decided several years laters to rebrand the french "Itineris" mobile brand "Orange" and progressively did the same across most of its business lines, both domestic and abroad.

Everything from landlines to datacenters to service centers is operated under a unified brand, Orange, originally stemming from this UK mobile operator. (I think there's a few things here and there such as live tv broadcast that have not been rebranded but I'm not entirely which and why).

The "France Telecom" brand has, I think, completely disappeared.

Funnily enough, through hoops of corporate history and divestment, there are now completely separated business entities in completely different sectors than telcos that operate under the "Orange" brand, such as Orange Bank in several countries, mostly sub-saharan Africa, that do not have anything todo with Orange/France Telecom anymore.

karambahh··on There’s a 30-year old dead Rabbit in Seven Sisters tube station
And, as every communications systems, it was abused (as mentioned briefly in the WP page) by stock brockers between Paris and Bordeaux via a side channel attack.

They used it to covertly transmit swing in trading prices between the Paris stock exchange and Bordeaux. If memory serves, they used unused symbols or abused error correction, I don't remember which, but from a technical standpoint it was pretty advanced and covert.

I seem to remember they only got caught because somebody snitched them when they suddenly got veeeery good a predicting prices in Bordeaux, some 400km away from Paris.

It appears transmission speed for a symbol was on the order of magnitude of 7 meters per second, and full messages travelled 400km in 9 minutes instead of 4 days by horse. So speed was a ginormous improvement despite low bandwidth and very high capex & opex and limited operating hours.

It operated from 1793 to 1854 in continental France.

karambahh··on Show HN: I made a new sensor out of 3D printer filament for my PhD
It seems to me that the refractive index plays a role: couldn't you increase resolution by replacing air by another medium every other cut? Say air, water, air, etc.

My reasoning is that you'd increase the resolution without adding too much technical complexity.

My maths is too rusty to evaluate how it would mess with the gray code though.

Very nice idea
