karambahh··on Tycoon Xavier Niel says he was spy who hacked ex-French president
Context: it was hanging in one of the rooms of the former HQ of Scaleway (an Illiad/Xavier Niel subsidiary) avenue d'Iena.

Among several others, I think there was Steve Jobs.

When the company moved out, to settle in its current buidling, the portraits stayed behind

Can you elaborate on this?

I've never heard before that they are trying to kill GCP?

karambahh··on Scaleway C2 and ARM64 instances will reach end-of-life in December 2020
As a former Scaleway employee, I can confirm the energy profile of the ARM racks were very nice.

It has been publicly said before by many, though I'm not sure we ever released any data publicly on this, so I'll keep this at the anecdata level

karambahh··on Firecracker: Secure and fast microVMs for serverless computing
I am actually surprised by the absence of AMD support for a project born at AWS. AWS has been offering AMD Epyc ec2 instances for quite awhile[0].

Missing arm support is also suprising but less so, as arm market penetration is obviously lower than x64

You're in fact absolutely right.

I've had countless encounters with C-level execs who could recognize that if theur point of sales software was down, it meant a loss of x M€/day, or that if this SCADA system crashed it meant casualties within the work force. They could be rational enough to attach a price tag to these events

Despite this, it always went back to "yeah but last time my computer crashed, little Timmy fixed it, it's a no brainer, and my IT director has these things called backups".

The same people have contingency plans for anything non digital (including services like Blackwater guys or kenyon and so on), but digital has "no real consequences".

I hoped the Maersk disaster of last year would lead to a change of mind, but unfortunately we're not there yet.

karambahh··on Airliner Repair, 24/7 (2008)
I am surprised by your comment: "After a year I still haven’t found a way to adapt their model to the IT world"

I have worked in "disaster recovery" modes within a larger group of companies (think "Berkshire Hathaway" large), where we were basically meeting regularly to discuss opportunities, new findings and, above all, knew each other phone numbers & area of expertises.

There were basically no issues wtr to the business model, as we were all owned by the same company and when were working in "commando/disaster mode" shit had hit the fan furiously enough for noone to care about the costs. That may have simplified the things a great deal...

To me, Kenyon (and a few other players in their fields) is nothing more than an on-call, dependable team of experts with pre-set rates and a yearly fee for availability. I know for a fact that companies dealing in IT security do have such contracts (there's been numerous articles in the press about the Maersk disaster a few months/years back) and would expect that services similar for every aspects of IT ("our billing system has been offline for the past 13 hours", "our main DC has just been destroyed by an earthquake" and so on...)?

What have been the blockers you stumbled upon?

karambahh··on Is Arm ready for server dominance?
Disclosure: I currently work at Scaleway but wasn't there at the time when we rolled out the 1st ever ARM baremetal offering.

It was massively cheaper than their x86 counterparts at Scaleway or competitors, thanks in no small parts to very clever electrical engineering by my colleagues.

I think we never publicly disclosed power consumption levels but.... let's say our ARM boards are very power efficient :)

karambahh··on Hacker Publishes 2TB of Data from Cayman National Bank
Because the social contract of most countries is that your legally gained cash is to be taxed in one form or another and thus has to be known by the tax authorities?

You can argue that your assets are to be private to the general public but some countries do not have that assumption (Norway comes to mind).

karambahh··on Tesla co-founder and CTO JB Straubel stepping down
Would you have sources about Toyota factories being less automated than their US competitors?

I've been told in the past that the key factor in Toyota success is their relationship with their suppliers. A top notch supply chain with just in time processes bundled with reasonable proxy stocks?

Would love to read about their automation level compared to US or EU companies

karambahh··on Notre-Dame came closer to collapsing than people knew
The only other military fire brigade is Marseilles "Marins pompiers"[0] that are a branch of the french Navy but I believe it to be standard practice in all fire brigades in France of which almost of all them are civilian.

Morals aside, it kind of make sense from an economical standpoint: a single guy dies, that's sad. A father of four dies, that's sad and the community has to support four orphans...

Controversial opinion: making that call to save living creatures is fine in my personal moral compass. Make that call for a building, be it symbolic and of rich cultural significance, not so much. As long as nobody is in danger, do everything to save it but if it burns to the ground, it can be rebuilt. A lost life and its consequences cannot.

I was, honestly, furious, when I heard the commander chose to send his men into the northern tower simply to save a pile of rocks....

karambahh··on Notre-Dame came closer to collapsing than people knew
The operations commander purposely chose personnel with no children or spouse to go on the northern tower

The call was made knowing that there may be casualties among them

Well, current archeologists need to have a vast range of expertise (water management, cooking techniques, building & more)

I've watched a few days ago a documentary about ScanPyramids, a team of nuclear physicists that used their knowledge to perform non destructive exploration of Kheops Pyramid:

https://en.wikipedia.org/wiki/Scanpyramids

It could be argued that they're top of the line physicists AND archeologists at the same time :)

karambahh··on Three geeks rescue a 50-year-old IBM 360 mainframe from an abandoned building
I'm glad some people take upon themselves to salvage important pieces of our past.

As the technology evolves extremely fast, it seems that traditional preservation & archeology institutions can't deal with these fast enough.

Salvaging IBM360s will probably have the same historical importance in only a few dozens of years.as 16-17th centuries artefacts today.

I know of several private initiative to save items of first era of home computing but salvaging industrial sized computers comes with severe logistics challenges, as these gentlemen demonstrated

karambahh··on Hertz bug leads to people being erroneously arrested and jailed
Afaik, German authorities would have to issue a warrant to Europol to actually have you arrested in another EU country. (And I don't see them actually looking for you for a mere parking ticket...)

What EU countries start to do is sharing the license plates files between countries.

I got a (non registered) letter in the mail 3 years ago from the federal police force in Belgium with no easy way to pay the fine (related to a speeding offense which I recognise I most likely did commit). Got them on the phone once but it came to nothing. (If a belgian cop reads this: I'm more than willing to pay :) ).

Interestingly, at the time, belgian plates caught speeding in France were not contacted so the agreement or its technical implementation were not reciprocal.

I also received a parking fine from Brussels city, which made payment simple & efficient via a SEPA transfer.

Europe is far less integrated than US HN users seem to think. Countries are sovereign, they simply choose to collaborate on parts of their legal framework, parts which can be different on a country by country basis.

For instance, Schengen (freedom of movement for visa holders of a member country, generally no border controls between them) is 22 EU countries PLUS Switzerland, Norway & others. Members still have the ability to reinstate full border controls if need be (was the case during the terrorist attacks in France & Belgium in 2015/2016).

License plates schemes and vehicles insurances (ironically, insurance certificate are called "green cards"...) are valid amongst the Council of Europe members (basically all of geographical Europe, Russia & Turkey included)

karambahh··on A journey through internet garbage
Anecdotal evidence: news source I read tend to switch from provider to provider every six months or so.

Either they are offered a great deal by the new incumbent or management gets fed up with poor revenue/poor targetting.

I've seen it happen 3 or 4 times in the last few years?

karambahh··on Automated Refactoring of a U.S. Department of Defense Mainframe to AWS
Sorry I misread your comment!

You're obviously right for licensing inside the emulator! However, the costs are(were?) in hardware & floor occupancy (as in "decomission a whole room"-cheaper)

karambahh··on Automated Refactoring of a U.S. Department of Defense Mainframe to AWS
It's been a long while.... At the time, RedHat was still "free".

Linux sysadmins were cheaper than their mainframe colleagues.

Hw was orders of magnitude cheaper.

Floor occupancy was lower.

We did not got as far as watts consumed per functional task performed but I doubt it would have tilted the balance?

karambahh··on Automated Refactoring of a U.S. Department of Defense Mainframe to AWS
I've worked on a similar project, we tested two different approaches:

Recompiling the COBOL codebase on Linux and accessing and loading it as shared objects (via JNI for JVM usage)

Running Hercules ( https://en.wikipedia.org/wiki/Hercules_%28emulator%29 ), an IBM mainframe emulator

The first one has lots of merits, as it allows for a progressive replacement of COBOL functionalities

The second one immediately lowers the TCO for obvious licensing reasons but does not plan for the future, particularly as COBOL developers retire and thus the resources are scarce.

(Anecdotally the customer chose both: recompilation & progressive replacement by Java code for core assets and emulation for "dead", non core, assets dev & staging environments)

karambahh··on Show HN: Office Hours – Hold office hours by phone anytime, anywhere
This is a very cool idea.

I'm officially a mentor in a couple communities and suffer the same pain with regards to scheduling.

I'm also mentored and I'm always debating whether if now is a good to talk and I won't bother my mentor.

It could also be used in a paying context. I do a bit of consulting about the saas solution we sell and its ecommerce ecosystem. We are of course happy to reply our customers but sometimes their contractors (particularly more juniors one) are hesitant to inquire about something and fear bothering me, especially when there's a timezone difference.

This tool could serve as a "yes, do "bother" me now, I'm actually open to discussions" indicator in many situations.

I'd suggest extending the indicator to email/slack/text and written communications in general as sometimes mentors or mentoree prefer expressing themselves in written form.

I think there's a market for this "omnichannel availability indicator", in both non profit/free and paid modes.

Please ping me when you release an Android version?

karambahh··on HermiTux: A Binary-Compatible Unikernel
Could you please explain why they can't be?

It seems counter intuitive to me. It seems you're saying that static analysis cannot reach every branch of the program (and thus its underlying system libraries).

I'm surely missing something and would be grateful to anyone helping me out!

karambahh··on Radiation concerns halt Brussels 5G development, for now
In Belgium, DAB TV has or is being retired because the whole country is equipped with cable tv.

It leaves more spectrum for 4G communications.

karambahh··on Car campers in beach parking lots
In all honesty, I'm not sure I understand your train of thought[0]: why would re-purposing beach parking into housing be dumb as an absolute?

There are probably places where that would be dumb and others where the community as a whole would benefit from increased housing availability?

Most of America has plenty of space but why would anyone agree to live in bumfuck nowhere? How could they make a living out of nowhere (remote jobs are, in the grand scheme of things, a drop in the bucket)? Why should they forego access to health services, community & the fabric of society? Some human beings enjoying being solitary but we all crave to various degrees of social interaction.

To answer your comment in a too simplistic way: if parking does take room away from shelter, yes, absolutely, that's very bad urban planning & if done on purpose is a "violation" of the rights of those who needed that shelter. Except that life & urban planning aren't always that cut and dry and we need parking space, shops, warehouses, factories, housing & animal shelters and a myriad other things, as well as stop urban sprawling as much as possible.

[0]there might be a cultural/language bias generated by me having english as a 2nd language

karambahh··on Car campers in beach parking lots
I think you're comparing apples to oranges here.

If you reclaim a parking space for another use (such as building accommodation for families or an animal shelter), you're not depriving the car of anything, it's an expensive, large piece of metal and is not sentient.

Next, you'll say that you're depriving car owners from the practicality of parking their vehicles anywhere they like. I'm perfectly fine with depriving car owners from this convenience to allow a human being to have a roof over their head. (speaking from direct experience as I've just minutes ago had to park my car 1km away from home because the city is currently building housing and has restricted parking space nearby)

Then, some might argue that one should be ashamed of helping animals while humans are suffering. That's the exact same train of thought with «we can't allow more migrants in, we have to take care of our "own" homeless people».

This is a false dichotomy. Western societies inequalities are growing larger and larger. Me trying to do my part is insignificant. Me donating to human or animal causes is a small dent into the mountains of inequalities we live on top of. Us collectively, we do make a difference, by donating, voting and generally keeping our eyes open about the world we live in...

Finally, an entirely anecdotal pov: I've witnessed several times extremely poor people going out of their ways to show solidarity to animals or humans. I've also witnessed an awful lot of extremely wealthy individuals complaining about the poor inconveniencing them by just being there, whose wealth was a direct consequences of their ancestors exploiting whose very same poor people.
