60 mbps is easily beyond the limits of many home wifi network setups, and leaves the serving end with capacity for something like 166 users per 10 Gbit port. There are many additional costs to consider beyond the size of the home pipe

Most online video uses crazily overspecified h.264 bit rates for low complexity content. It's often possible to get 1080p well under 2 Mbit/s with little to no quality loss, and even lower by using 2 pass encoding where that's available. I'm not sure how things are with h.265 in a production setting, but at least for home use it seems to have much of the same flexibility

Yep, every time I use the account switcher. Seen this happen a bit previously but now it seems constant.

Makes plenty of sense if said employees no longer have access to source code by the time the interview takes place. Red Wedding silicon valley edition

I think it is better to think about it as XDG failing to respect a world that existed long before it did. $HOME/.* namespace belongs to the user, but contents are special. It's almost like complaining about Linux enforcing the naming of certain file extended attributes.

This is hoping for some technical means to erase the transgressive nature of the concept itself. It simply is not possible to reduce harm to children by legitimizing provocative imagery of children.

This is advocating for increasing the number of victims of CSAM to include source material taken from every public photo of a child ever made. This does not reduce the number of victims, it amounts to deepfaking done to children on a global scale, in the desperate hope of justifying nuance and ambiguity in an area where none can exist. That's not harm reduction, it is explicitly harm normalization and legitimization. There is no such thing (and never will be such a thing) as victimless CSAM.

Would be curious about OS / input/output size / hardware/virtualization tech, the only reason I can think for this would be tiny buffers with exorbitantly expensive context switches like you'd see on some older virtualization or e.g. puny escaped-a-VCR ARM chips

New comment by crazytalk in "IBM swallows Red Hat storage products"

crazytalk — Fri, 07 Oct 2022 17:07:52 +0000

> all IBM wants to do with Redhat is turn it into IBM

Reading the histories of both companies, it seems to me that Redhat was always IBM. The acquisition was a marriage of separated twins more than anything else, the dominating culture in both organizations is largely sales and consulting driven, with public strategy not quite identical but strongly rhyming. The technology aspects (while perhaps once important) were far from the prime focus of either organization long prior to the merger. I think of IBM's acquisition more as a desire to access marketing expertise and established sales channels than anything to do with technologies, most of RH's open source technology is after all mostly just an advanced form of disguised marketing

Looking forward to runnable code this time. Most of us are old enough by now to remember many project plans just like this one. Fool me once..

New comment by crazytalk in "Measuring CPU core-to-core latency"

crazytalk — Sun, 18 Sep 2022 20:34:54 +0000

It's mentioned in the readme - this is measuring the latency of cache coherence. Depending on architecture, some sets of cores will be organized with shared L2/L3 cache. In order to acquire exclusive access to a cache line (memory range of 64-128ish bytes), caches belonging to other sets of cores need to be waited on to release their own exclusive access, or to be informed they need to invalidate their caches. This is observable as a small number of cycles additional memory access latency that is heavily dependent on hardware cache design, which is what is being measured

Cross-cache communication may simply happen by reading or writing to memory touched by another thread that most recently ran on another core

Check out https://en.wikipedia.org/wiki/MOESI_protocol for starters, although I think modern CPUs implement protocols more advanced than this (I think MOESI is decades old at this point)

crazytalk — Fri, 16 Sep 2022 15:25:42 +0000

Alleged Russian bot here, I was torn apart in a thread about the European energy crisis for attempting a balanced perspective. It's sad to see, but not really worth the time trying to fight against it. The vast majority of folk seem actively happy to be misinformed, so long as that misinformation is consensus among their social circles. Better to use the information as some kind of indicator of the demographic you are interacting with, and act accordingly (most probably, find something better to do)

crazytalk — Mon, 12 Sep 2022 08:40:26 +0000

Random thought: if the commercial web has all but devoured the original web, leaving only a fraction of the interesting parts behind and which are no longer really growing in number, isn't this counter to the reason why we decided we needed search engines altogether? Wouldn't it be nice if someone made a modern Yahoo! Directory equivalent for those random olde worlde curios we all pine for? Something like a modern decentralized Geocities

Do they even maintain something resembling a backbone? A lot of these CDNs just use public transit for outwards traffic

crazytalk — Sat, 10 Sep 2022 18:27:15 +0000

Much easier to get a global view of Internet behaviour when there are only one or two DCs worth of ClickHouse clusters needing tapped

Related question: given this obviously generates logs, what are CloudFlare doing to protect log data in transit within its own network from similar attacks to the Google-NSA episode? ( https://www.washingtonpost.com/world/national-security/nsa-i... )

New comment by crazytalk in "Pypi.org is running a survey on the state of Python packaging"

crazytalk — Wed, 07 Sep 2022 20:55:19 +0000

This survey is the literal definition of leading question. Found about 2 boxes I could tick, before being forced to order a list of the designer's preferences according to how much I agree with them. The only data that can be generated from a survey like this is the data you wanted to find (see also Boston Consulting Group article earlier today). I cannot honestly respond to it

The only question I have is, what grant application(s) is the survey data being used to support?
