Submission + - CERN Open Sources Its KiCad Component Libraries

ewhac writes: CERN, a long-time Open Source pioneer, has made several contributions over the years to KiCad ("KEE-kad"), an Open Source EDA (Electronic Design Automation) package widely used in the hobbyist and professional electronics communities. It's gotten so widely used that users can now submit their KiCad design files directly to several electronics fabricators (rather than the traditional step of converting the layouts to Gerber files). Over the years, CERN have also developed their own symbol and footprint libraries to support their own internal electronic designs. Last week, CERN released those KiCad component libraries, containing over 17,000 symbols, under the CERN Open Hardware License (permissive version).

Comment Curl ism’t myths “target" (Score 1) 63

As I understand it Mythos’ “big leap” is not in finding specific flaws it is in chaining them together into a “bigger” flaw. So finding a minor issue in curl that lets you put a file where you shouldn’t, plus a flaw in something that assumes some file location is “safe” and it doesn’t have to parse things with an advassery in mind, plus a flaw in something that relies on that thing, and so on.

When doing that kind of security work you don’t need to find a bunch of significant flaws in each tool, just a minor flaw in places that turn out to be useful when combined with say up to 9 other minor flaws. So from the viewpoint of cUrl which doesn’t rely on a lot of other tools to provide its services nothing has changed. The pain is experienced on a wider scale like over a whole OS where there are a lot of tools any of which might contribute a minor flaw so Mythos can find way to gain “the prize” (maybe remote execution, or a privilege escalation, or both).

Maybe a better way to think about Mythos is it doesn’t have to hyper focus on one tool like “can I break into the system using cUrl?” (and is not actually any better at that question then prior AI), but it does a far far better job at answering the question “can I break into the system using up to a dozen or so flaws together out of this pool of 1000+ tools?”. I assume it may be a bit better at finding flaws in single tool if the flaws require putting more bugs together or more steps to reach the state where an existing flaw shows up, but again that isn’t the big deal. The big deal is at a system level it puts multiple sub-critical flaws together to combine into a critical flaw. (queue transformers joke here)

Is Cuda a lock in because there is a critical mass of solutions written in Cuda and people that think about problems in terms of Cuda already so nothing is really going to unseat it that isn’t a close clone of Cuda and making one of this is for some reason impossible, or is the problem that you can make something else that lets you be expressive in the imprint ways Cuda is while giving the backend the same kind of flexibility to schedule operations, but nobody else has made one that isn’t “too buggy” to use on real world problems?

In the distant past very few C/C++ complies existed, they were “too complex” for small companies to make, and now we have very few commercial compilers and a billion open source projects that are all forks of gcc or llvm (or a fork of a fork of the llvm derived clang). We don’t have a billion non-C derived programming environments though (we have a few, JavaScript is popular, and I’ll argue Java is C-derived, although removing pointers form C doesn’t leave a lot, so I’ll also accept it as a distinct environment, but if so, so is Swift, and Rust also counts as distinct...still that is only handful). It doesn’t prove a lot, but I would say even the moat of a programming language and environment only lasts so long.

there's no long term impact. it's just for construction.

Do you actually believe that? I mean, yeah sure “we asked them what was up and they gave a flimsy excuse” doesn’t mean you have to believe it!

The only thing that points towards them maybe telling the truth is it might be obvious if the data center were operating and you don’t want to get caught in a provable lie. However it is also possible the data center is partly operating while construction continues and they figure “hey there aren’t people coming and going, who will know if the data center is operating as opposed to testing equipment if we get caught!”.

Comment ISDN: It Still Does Nothing (Score 1) 95

It still amazes me that, as late as the 1990's, and well after 56kbit modems were prolific, ISDN was being offered up by the ILECs as "broadband," at metered rates that made Ma Bell's long distance charges look like spare change.

Happily, it wasn't too long before ISDN was put out of everyone's misery when DSL showed up. And now, finally, after fifty years of pissing about, fiber is finally being pulled to the premises.

If you really need ongoing ISDN support, you can pull the source code from an old Git commit and update it. But I feel quite comfortable in opining: ISDN support will not be missed.

Comment Re:Neo is basically for educational ecosystem (Score 1) 68

e benchmarks I saw had it about the same. The 2020 M1 Air slightly faster in single threaded, slightly slower in multithreaded, or do I have those two swapped. Either way, it's abouth the same overall.

Geekbench puts them at Neo 3535/8920 (s/m) & MBA 2347/8342 (s/m). So the Neo is significantly ahead on single core performance, and ahead (but just barely) in muti threaded even with the reduced core count! Which is decent for half the price! (well if you get the EDU discount on the Neo, the M1 MBA doesn’t have a EDU discount that I know of).

To be clear at the price point not too much slower would be Ok, but the benchmarks have it at way faster for single thread, and faster but basely a tie for MT.

To be honest a used M1 Air or M3 Air would seem a better deal

A used M1 Air at under the Neo's price would be a good deal. The M3 at the Neo’s price would be a great deal. I mean the Neo is pretty damn good at its price point. It is fast, it works surprisingly well for its RAM configuration. The +$100 model has touchID and slightly less pathetic local storage. The Neo’s display is physically smaller, but the whole device is quite small, some people prefer smaller devices for carrying about and use in cramped areas. I mean from my view point (16” MBP with large external displays) both the Neo and MBA have tiny cramped displays! However both are shockingly fast for their price.

Comment Re:Repairability? (Score 3, Interesting) 68

The MacBook Neo gets a fairly high repairability score. Most people who have disassembled it seem to be of the opinion that since it isn’t going for absolute minimal size and weight they used very few adhesives and lots of screws. So it is pretty simple to take apart and put back together. Apple does also make “self repair” kits for many products amiable to rent with an unreasonable deposit (purchase also available, but not useful to most people), but has apparently decent instructions and such to get things done.

As for upgradability, nope, they are headed away from that as fast as they can. No RAM upgrades on any modern Apple device, the RAM chips are wire bonded to the CPU, which at least means they use lower voltage swings and get somewhat better latency out of the same parts. Not in general a tradeoff I would make (I would rather have DIMMs and be able to do a late-life RAM upgrade to get more useful years out of a device rather then be stuck at my purchase RAM allotment forever -- and/or buy a low RAN model from Apple and do a day 1 3rd party RAM upgrade). To be fair to Apple customer installed RAM, and factory installed RAM that managed to work loose were the number one and number two repair issues for their upgradable devices (or maybe just laptops?) prior to starting to solder down RAM. Which statically means a shit ton of people thought Apple just made crap computers that flaked out at random and never brought them in for someone to tap on each DIMM and “fix it”. So soldering the RAM down decreased warranty repair costs, decreased out of warranty “customer comp” repair costs, and increased perceived reliability amongst people that don’t take flaky laptops into an Apple Store and try to get someone to look at it.

The obvious downside is I pay more when I buy a Mac either because I don’t buy enough RAM for the full useful lifecycle of the CPU, or because I do and Apple charges a lot of money for it (well until recently, due to long term supply contracts Apple’s RAM cost is very low, so the normal 50+% profit margin they take on RAM now seems highly competitatave with spot RAM prices)

Comment Re:Neo is basically for educational ecosystem (Score 1) 68

The Neo is nerfed in way to reduce cannibalizing the Air. It 2020 M1 CPU performance with a smaller screen and slower I/O.

Or alternately it is intended to be a replacement for keeping the 2020 era M1 MacBook Air around for “special retail partners” (i.e. Walmart and Costco) to sell at $799. The MacBook Neo other then the I/O much faster then the M1 MacBook Air, and in various “whole system” benchmarks apparently the slower SSD doesn’t really impact it too much. Which blows my theory that the M1 at 8G could get so much done without feeling slow because the SSD was fast enough that it blunted the effects of doing VM page-outs/page-ins.

The Neo will make money, but that will be largely due to growth in the educational ecosystem. Maybe some other Chromebook niches.

It seems very popular for people who “always wanted a MacBook” and never could convince themselves they could afford one. I don’t know how many will be repeat buyers (let alone climb up the product chain to the Air). If they are satisfied with the Neo they don’t need the next Mac to be faster. If they are not satisfied with it, will they blamee that on “Macs suck!”, or on “The Neo is just entry level, I need to spend 2x to 3x to get a faster one!”.

I do see a ton of people talking about getting one as a first Mac, or having bought one and asking all the “how do I make it do (some random thing they miss from Windows)” questions.

Except he isn’t retiring, he is stepping down as CEO and assuming the Chairman of the Board position where he will be specifically responsible for interfacing with world leaders (i.e. more sucking up to the orange man). Which is nice for John Ternus I guess because he can run Apple without dealing with(directly) with Trump, and let Tim deal with tossing golden trinkets at him and assuring him Apple is bringing manufacturing to the USA while talking to every other world leader and assuring them he is bringing manufacturing to them, and to China and tell them manufacturing is going no where and all the other things are just tiny slivers of inconsequential volume to appease random world leaders.

So no, his replacement isn’t kissing any rings, Tim gets to keep kissing the same rings. I don’t know if he enjoys it (I suspect not), or just thinks it is his responsibility, or can’t liquidate his stock fast enough to deal with the fallout if Apple stops being favored by Trump (Tariff bypass) and starts being targeted (special Tariffs, and more levers that a President could pull...like having someone hand inspect each iPhone before it comes through customs which would move a scheduled launch day back by weeks, months or years depending on how slowly the inspections are carried out).

To me the hoops that smoothbrains will jump through to avoid IPv6 and stay on legacy IPv4, especially when hosting, is pathetic. NAT, port forwarding, tunnels, blah blah blah blah.

I have something like ~1.2 trillion times the number of routable addresses that the entire IPv4 space has. Not all are reachable, of course, just the services that need incoming access and they're each on their own isolated DMZ.

Comment My home network is nearly pure IPv6 (Score 1) 73

Started the move about 18 months ago when I decided to get off my lazy ass. My ISP gives out a /56 prefix, so that lets me run 256 /64 subnets/VLANs in the house, currently there are ~10 in use. Everything get a GUA through SLAAC and I use RAs (Router Advertisements) to give ULAs to everything. Any external facing services get their own VLAN and /64 for the system(s) as needed. Firewall blocks all incoming as they usually do by default and I punch a hole for the external-facing systems. They can't reach back into the network, they only answer the phone. All the systems update DNS dynamically if the prefix or full address ever change.

I have an SSH bastion set up. In all this time there has not been a single SSH attempt from the internet. On IPv4 it was constant background noice.
For those legacy IPv4-only systems on the internet, I set up NAT64. I have an IoT VLAN and IoT 2.4 GHz wireless network that are only IPv4 because a lot of IoT network stacks are junk.

I'm still farting around with it, but man oh man, there's no way I'd go back to IPv4. It was one of the best moves I've done in ages.
