That's not quite the same though. The claim is that because I'm a habitual user, I'm always impaired. Which amounts to over 100k miles of impaired driving over the last decade.

You probably are compared to your baseline self (another comment goes more extensively on this subject) but maybe you have enough driving skills and common sense to minimize the risks somewhat.

Guys,

I watched all the alien movies.

We should not trust those things that come from outside planet Earth ...

icefo commented on Proper decoupling capacitor practices, and why you should leave 100nF behind   codeinsecurity.wordpress.... · Posted by u/zdw

Most of the advanced chips (the 16 nm that Xilinx uses for UltraScale/+ and below) are flip-chip wafers and have an interposer which is basically a very dense PCB that helps fanning out the extremely dense and small pitch of flip-chip bumps. They will usually include extra low impedance ("landscape" orientation) capacitors on the substrate, which leads to much relaxed PCB decoupling requirements.

Having designed FPGA boards with both their 7th generation parts and their Zynq UltraScale parts, the internal capacitors are such a time and cost saver in terms of being able to fan out more signals without more PCB layers

I can also attest that even relatively "slow" chips like 14 nm FinFET MPUs from Renesas have decoupling caps on the substrate

Do you make SoMs for a reseller by any chance ?

I'm looking at the newest versal chips from Xilinx/AMD for a new design and buying a SoM & designing our carrier board could fit the bill nicely. We're still very early in the design process, we need to get prices for the chips too to see if it's an idea worth pursuing.

Not sure why all these submissions are dead - vouched for this one (as it had a comment at least). Even though we see only 1 side of the story, I find it very important that it is definitely a sign of very big changes in the kernel-governance (which have been brewing since a couple of years).

(Offtopic note: title is editorialized unfortunately, but still important)

I don't often post here (I forgot to check the guidelines), should I have left the original title "(bcachefs) Trouble in the kernel" ?

While the article that follows is well written, the original title feels very vague and clickbaity for me. Like "you won't guess what's wrong with this !!!".

I felt this give a much better idea of the content (technical problems that exposed people problems) and give chance to people that don't want to read about kernel politics / drama a chance to skip the article.

We only have the point of view of becachefs main developer here of course, but some things regarding some kernel developer and the CoC committee seem to be really concerning.

Getting closer to Jim Gray's "smoking hairy golf ball" (Jim also forecasted that chips would eventually become spherical to limit the lengths of the data paths.)

It will be interesting to see if commercial data centers re-fit with cooling water transport under the floor or above the machines (riskier). This will be a challenge for DCs without a lot of space under there, presumably they could boost the floor height after a door transition. Still how many of them have 20 - 40kW of power allocated per rack.

Its one of the few times I miss being at Google because they approached this sort of problem very creatively and with an effectively unlimited budget to try different things. I'm sure their data centers are very much different from my time there!

I had the chance to visit the new datacenter of my college and on the server exhaust side there is a radiator as tall as the rack with cold water in it. All the pipes are under the floor.

IIRC they mainly put power hungry compute nodes for the clusters in this new datacenter and I remember that servers full of GPUs had crazy power draw. The water then goes through an heat exchanger to help generate hot water to heat the campus and for the taps.

> have you organised illegal activities through encrypted chat communications

If I did, why in hells name would I tell you?

Why would you ask that in the first place? To catch out the incredibly dumb terrorists?

icefo · 3 years ago
To put you in prison if they find by some mean you did.

The mean could be a 5$ wrench, hacking into your devices or plain old surveillance

During the Trump/Biden elections, I distinctly remember the "these elections probably are also being manipulated by the Russians right now" narrative being dropped the moment it became obvious that Biden's winning. Well, if the right candidate wins, the elections must have been fair.
icefo · 3 years ago
The elections can be skewed with different kind of manipulation (social media, troll farms, electronic ballot hacks) and the popular candidate can still win.

It's fair to assume Putin would try to influence the elections in trump's favor as he would have been beneficial for him.

The Ukraine invasion would have been much easier if trump had been relelected, finished pulling out of nato and kept the more isolationist policy that was in effect during trump.

IMO trump was also doing a lot of damage to the US and it's position on the world stage which is also beneficial for Putin.

I think this is a pretty key point. If a business is going through any kind of rapid change, cloud providers offer a lot of off-the-shelf help for that, be it ability to scale, hosted infrastructure, or PoPs in new geographies. If the company is relatively static with easily predictable future requirements, you can get a lot more bang-for-your-buck by handling things on your own and developing your own in-house expertise.
icefo · 3 years ago
There is also a third approach that is the best if you have a predictible base load with surges sometimes imo: hybrid cloud

You basically run the base load in your own data center and the surges go to the cloud. My university is evaluating this because sometimes you have multiple labs that need a lot of compute resources at the same time and local compute cluster has finite capacity.
