Nvidia open-sources Linux kernel GPU modules. Repeat, open-source GPU modules

Re: Gonna wait for a couple of years to see this.

INTEL could be interesting. My problems with intel date back to the 8080. NONE of their chips ever seemed to meet their specs. There were hardware work-arounds, software work arounds, they were actually so awful it spurred the 'chipset wars'. Almost forgot the math problems, hell even their current crop of Wifi chips have issues that seem to plague linux and windows. I think in the past things have been hyper-tuned for intel to work around stuff. Graphics issues could take things to a totally new problem level, but at least you might see a reasonable working open driver with manufacturer support for linux.

Re: Gonna wait for a couple of years to see this.

Ditto.

Plus time spent downloading and compiling and whatnot and DKMS problems, hyper kernel version specific code, and more downloading. I've never had a linux/NV stay even remotely stable through more than a handful of kernel updates.

AMD/ATI just pretty much worked, though I do get spurious ECC errors supposedly linked to an issue with the new AMD stuff. Not sure, but the system doesn't crash.

Re: Brilliant!

Defamation is indeed incumbent on presenting untruthful information. It gets a bit grey when politicized. A politician here was accused in a hit piece of having come out against contraception, and having written a paper (when he was 19) that was pro-nazi. This was picked up by a few national media outlets and published as 'facts'.

To the credit of some in the local media here, we find apparently the paper (which the gentleman stood by) used the Nazi party as an example of riling up the people with a cause to creating a drastic political shift. There was no record or incidence of him ever speaking against contraception, in fact he was on the record as just the opposite.

But the damage was done. Any corrections are on page 9 or an honorable 2-second mention at the end of a broadcast. He's suing for defamation. I agree with the sentiment of the suit, but on one hand the hit piece folks could claim it as opinion, and the National media outlets will just say "oops" and print a retraction on page 9. Just try and stay informed. The minute someone uses the term "Orange" or "O-buma" it's high index talk designed to inflame, you should skip the comment.

"The Wall"

"The Wall" was being built. "The Wall" is not really the great wall of china. In fact up until about a week into the current administration sections of wall were still being put up in key areas along the border, and then the materials were simply abandoned. Arizona was trying to obtain the material to continue the project but was thwarted by President Biden's administration. Ditto in Texas. Ms Sinema knows she doesn't stand an ice cubes chance in hell of getting re-elected if she supports some of the idiotic things our current administration is doing, so while I disagree with much of her politics, I find she apparently does care about the state she grew up in for which I am grateful.

I love it when someone who lives in another country, or behind fenced and guarded neighborhoods with security want to bash "The Wall". For the former, carry your ass down here, and live on someones property near the border for a week with them. For the latter, you are some of the biggest hypocrites, and it's a shame all you and your friends in the media who live with you have such loud lying voices, that you convince or manipulate people to your way of thinking to screw them over.

"if things are really that bad where you live either get off your fat asses and vote in a government that'll fix the problems, or fucking move!" -- Really?

Move where exactly, into what exactly, for how much approximately? You see the politicians want to spend the money on 'light rail" and "mass transportation" products for all of us who don't live in gated communities with armed security. At least I don't live in Seattle. So they drive their Tesla's and Audi's and E-Class's back and forth from their secure compounds to their secure work buildings with more armed guards and fences. And tell me to ride the bus/rail.

Somehow these clowns use the media to convince the sheeple of the unwashed masses they are doing them favors, taking their money, while the bus stops and rail stations are swimming in homeless people, many of whom are aggressive to say the least. There is a homeless enclave under a bridge / overpass close enough to throw a baseball from the side of the building where I work, a stones throw from the cars in the parking lot. People are literally pouring over the border, If you don't believe it just drive down near Tucson/Nogales or Yuma out in the desert. I suggest you be armed, and have a buddy or two.

I don't have $1M to pour into a safe place, behind bars with $500+/mo dues. I carry either a SCCY CPX-9 or a Springfield XPS-45ACP.

I have a TNW survival (45ACP) for if I ever need to skedaddle to the hills. Nothing over $1K, but I'm not judgemental. I'd love to move, and I'm looking, but by keeping interest rates artificially low for the last 20 years, investors are buying up all the housing and then leasing at exorbitant rates.

Re: Did Musk ever really intend to buy Twitter?

I would expect to see a two-fold (maybe three) increase in density in 5 years. Several tech companies are claiming to have lab'ed new battery tech. One out of Australia is shipping prototypes, and ramping up for pouch batteries. I expect some mass production hurdles, but like the flat screen LCD panel, there is a huge market for several big players, and the technology is evolving rapidly on several fronts. Expect to see a reduction in the need for 'Rare Earth's as things progress as well.

Lithum ION is the near term solution, and will likely be on-ramping some of the aforementioned items like safety and longevity before sodium and aluminum et. al. technologies become viable. It's going to be interesting I think.

Re: Problem

China, Russia, and N Korea can (and do) produce X86 ISA or ARM ISA parts as well. Hell I could probably cobble together some (painfully slow, single threaded) silicon using discrete parts that that would honor an X86 ISA. RISC-V is an ISA... Instruction Set Architecture, ie a list of low level primitive commands about slinging data between registers and memory and maybe an I/O bus if it's not memory mapped.

Making silicon CPU's that properly implement the ISA, and offer performance, and pipelining and branch prediction, and ... That is a whole other ballgame. The best 'western technology' would actually be pretty much in Taiwan at this point in the far East but I digress.

It's the implementation of the ISA that matters, not the instructions themselves.

Re: Serious question

I'd go more with, someone decided to create a language that would (eventually) do everything you could possibly ever want to do with a system or database by adding 'modules' and roll it into a big giant mess that makes PERL look good. This is similar to what IBM did when it went from OCL on the 34/36 to QCL and then onto compiling CL for 'performance' and now I can have input forms on my CL! Every time I've tried to do something with powershell I've had to get a module, or something, and then everything is an object, so often the result you get is not what you expect, or requires further parsing or... It's just very darn inconsistent from function to function, and then the function you found that does what you want is only for Azure, not a domain controller, and ...

Sorry, but I'm not overly impressed with powershell to this day. dumping write-hosts's to see things in loops often fail to reveal actual object content that breaks somewhere else, blah, blah. Working with objects is great as long as you have a thorough understanding of each and every object you use. You are a maze of twisty little objects, all different.

I think shells and shell scripting should really be GLUE logic for weaving things together. If you want to get serious write some real code, in a language designed to accomplish the task, and use your shell to weave it all together.

And I'm happy to help tar and feather the idiot that decided names should be quoted and escaped by default in a directory listing on modern unix breaking scripts. (ls -1 | ...). The minute you make a 'shell' that is all things for all people, what you end up with is a 'thing' that is a necessary evil for a lot of people.

Nvidia CEO: We're open to Intel making our chips

The Pork Cycle

Not this time mee thinks. I just don't see a reduction in demand at this point forward. Further, fabs have to be re-architected every few years. I think the unseen problem was the demand boom coming from the micro-controller type markets. Demand for the small cheap stuff exploded, then dipped with the Covid nonsense, then re-exploded. A bunch of the new low news profile fab capacity is going to fill some of that need. The latest 1nm fab get's the headlines to make the next crazy fast mining chip, but the shortage is because everyone fabbed up to make all this high end, high profit stuff and ignored all the low end markets. They will come on line ramp up, and prices may fall briefly, until the word get's out that you can make that widget we wanted to build now, and then things will stablize. Keep in mind even an SOC has a bunch of support components to go with it. Most of that crap still comes out of china. All the high-end fabbing going in will pretty much just keep pace, with retiring old fabs, and expanding capacity to level out current demand. Intel is well aware of the cycle, has done a reasonable job of getting new fabbing online as old tech is retired. Micron, and Samsung, and so forth are in the same boat. They are constantly getting new fabbing in the pipeline, but they have to amortize out the costs sanely.

Re: 600W for a GPU?

I offset the down vote, why would you do that to provable fact? Makes no sense. I've often wondered, since amps determines wire gauge, how you step 12v @ 50a down to 1 or 2v at 200+ Amps and don't need double ought wire. . .

P = E * I ... 600w=12v*I, I=600/12=50a ... 600w=1.2v*I, I=600/1.2=500a

"Current" (ugh) chips generally run around 1.2v so that is a lot of electrons generating heat, in a space the size of a pinky nail.

Re: Confusing a language with an architecture

"But no, the architecture is not the point here. The point is that IPC, library calls, and system calls all inherit the insecurities of C, even where no actual C code is involved in either side, because the C conventions are the de facto standard that all programming languages adhere to for interoperability. This is how an Ada process reads an error text from another Ada process as an interger and Ariane 5 explodes, because C inhereted type unsafety from BCPL."

You just made my point... -Architecture- IS IPC, library and system calls and all that nasty talking back an forth stuff, and device driver interfaces, and shared memory, and ... Like DBUS on a desktop is architecture not language.

The article implies C is somehow awful because someone based a poorly defined architecture with it, to the point that when the underlying hardware became more robust the architectural definitions became perverted. The fact that nobody has redesigned the underlying architecture to allow for a more robust and well defined "MI" layer to handle all this is not a problem with the C language, it's a problem with not designing a robust extensible architecture to compile your programs against.

Again, IBM solved this "Interface Definition" problem in the 80's so that their systems could become 100% CPU/hardware agnostic. It seems Apple has defined their systems architecture well enough to change CPU architectures 4 times over their lifetime. Moving from big to little endian is decidedly non-trivial. The Wintel world was a free for all based on the original IBM PC and intel based chips. The fact that nobody deigned to design a proper "MI" layer for commodity PC hardware has nothing to do with 'C' as a language.

"Rust and Swift cannot simply speak their native and comfortable tongues – they must instead wrap themselves in a grotesque simulacra of C's skin and make their flesh undulate in the same ways it does." ®

Paints an interesting picture. Create an MI layer, write the horizontal and vertical microcode, likely lot's of assembler. Make it extensible, define everything you can think of, ... memory map all your IO and IPC. The write your OS against the MI without 'undulating' in a 'grotesque simulacra' of any kind. It's been done before, I've been mildly surprised some university never made a project out of it.

Whenever I read stupid sh*t like the above statement it makes me want to puke. You want to do IPC differently from 'C' with the latest language of the hour, shut the f*ck up and write it, and nail the API down. The bottom line on all this boils down to assembly language on your cpu of choice.

Confusing a language with an architecture

Sorry, The author is confusing a tool (C) with a systems architecture. I love C, don't use it much any more, prefer to write most things I do in shell or PHP, . . . YMMV.

As for a fully structured platform architecture, IBM solved this problem in the 80's with the AS/400 (now iSeries). They created a fully functional MI layer, layered on top of HMC/VMC layers creating a 64bit canvas with fully memory mapped IO and tightly defined data types. It was closed, but WAY ahead of it's time. It tended to be rather sluggish as well, They published a number of papers, but you basically compile everything to MI (Machine Instruction) and follow the guidelines and the tools all keep you honest. Everything works and talks in exactly the same way. The security models were interesting as well, everything was an object, and it didn't support a tree'd file structure... You could restrict any object many different ways, with ACLs, membership, location, ... At the time I thought it was arcane. Looking back I get it now.

Frankly it's sad nobody ever adopted these ideas into an open source OS. As a ground up approach, It completely hides everything underneath, and makes all your programing 100% agnostic to the underlying hardware. Unfortunately the overhead on 80's hardware had everyone bypassing BIOS and scribbling directly on hardware for performance dooming us to the current plights.

Doppler shift. Really? So somehow because my car (or golf cart or ...) is electric itceases to make *ANY* noise? Sorry, but electric motors make noise, tires make noise when they roll, sometimes on crappy roads or gravel an order of magnitude more dB than a any car noise. I have several deaf friends, no blind ones, but I used chat not infrequently with a guy who rode on my city bus to work with a seeing eye dog. He actually mentioned one time he was annoyed by some of the over-loud backup beeps on trucks because he couldn't always tell where they were. I'm not blind, so I can't speak past that.

So you put forth a premise that 'doppler shift' in sound of a modern ICE vehicle helps blind people identify moving vehicles and keeps them from getting run over vs an electric car. Do you have a reference or study materials on this? It's a lot like 'Masks Prevent Covid', because your spit doesn't travel as far. 'Well it has to do some good', except in the real world, you just can't actually connect the dots. Lot's of opinions, lots of seeming valid premises (Gee that sounds right) but the pudding ain't got no proof.

The other part is ear 'training'. Since most vehicles have been rather noisy on the outside what you have is a recognized sound. Electric cars also make plenty of sounds without the stupid ESS boxes, but they are simply not as familiar / recognized.

EV energy cost vs ICE/Hybrid

I've got a Niro EV, a Kona EV and a Sonata PHEV, (and an RX-8, but I digress). I don't care for the Tesla myself, but I think the Model 3 is the most sold EV around, it passed the Leaf in 2020ish. Tesla's mileage estimates are aggressive. OTOH the Niro is very conservative. Rated at 249, I've driven around 260 on a charge with the GOM showing another 50 or so miles of range. Some guys in the UK (U-tube) grabbed an LR model3 a Niro, a BMW? VW, something else... And drove them literally to dead. 70MPH on the freeway climate on, blah, blah. Model three went the farthest but only like 280/290. Niro came in 2nd ~270+ . Pretty interesting.

So I don't know what you pay for leccy, but I calc'd my break-even with 3.00/gal gas to be around US$0.28/kwh (vs the Sonata when running pure hybrid, at around 40MPG). 64KW bat pak, means around 64KWH for a "full tank" which assumes you were not "dry". There is overhead in charging. ~10% actually a little less, so 64kwh gets you ~ 58+kwh of usable power. I pay 0.07 off-peak so $4.50 for 225 miles (conservatively). $0.28 brings a 'tank of fuel' to $18/225 miles. roughly the same as 6 gal of gas (240mi).

Just some 'rule of thumbs' to keep it honest. The biggest difference is an EVs efficiency can vary wildly based on driving conditions. Keep it under 50-60mph (my commute) and stay out of temps below freezing and you can really push your mi/kwh up. I average well over 4.0 in both EV's. So unless you were paying Blink/EVGO/EA prices for your leccy, (.30-.50/kwh) AND you got your gas for 3 bucks or less (Not in California) not sure where the math was coming from.

Assuming your leccy is 0.28 or less, ie you are charging at your home or office, you'd be hard pressed to match energy costs with a hybrid. Not ever gonna happen with a pure ICE vehicle.

Unless you are driving a Corvette with the "Deep Sound exhaust BS" turned on, I'd bet the DB level of an EV backing up is not appreciably different than a new SUV.

Hmmm, I just dumped my 92yro father's Windows 10 box that was a disaster and replaced it with a Debian 11, running KDE/Plasma, Firefox (Which has "all his programs on it"), LibreOffice (He cut his teeth on WordPerfect, this was a little painful), Thunderbird (Which he has used forever). He was stunned about how much faster it was than his old system. I set it up to "auto-vpn" over to one of my servers, and now I can just "RDP" over whenever I need to or use KDE screenshare. Zoom works as well, don't even need teamviewer anymore.

I might mention all these boxes connect to my OpenLDAP server for authentication, and use Keepass backed to a private nextcloud server to store all their passwords. Now Openldap is decidedly non-trivial , and setting up the nslcd and sssd frontend's on the machines is not a 'user' process, but at this point the only reason you don't see more Linux on desktops is pure momentum, and the fact that way too many Windows Admins get lost if they can't click a checkbox.

Static compile

Static compile? Why? Shared libraries solve so many problems, if something is broken you just fix the shared library and all the programs that use it are instantly fixed.

No Really! (ROTFL, my sides will be hurting soon).

One of the reasons I can tolerate "App Image" is it's basically a static compile. My problem with todays 'static compile' is unlike the static compiles of old where you used 'ranlib' and 'ar' files and only included relevant portions of the library... Today's static compile just includes the whole thing every time. So it's basically an App Image. Which could easily be done by putting all your crap in a folder tree somewhere, use (say) apparmor to restrict it's access to resources outside that folder, and set your library path local for specific copies of any highly volatile shared libraries you might be needing.

Kubernetes and Containers just creates another layer of bulls... to debug. I just had an argument with a fellow at work, that was struggling to define what a 'container' buys me over a tiny VM guest. Apparently another layer of management, with some flaky tooling is a "Good Thing". Apparently this somehow saves overhead, but I'll be damned if I see it in practice. It's basically a chroot type jail (which I'm not a big fan of either) built into a virtualized "container" that depends on the virtual machine, that depends on the hypervisor host, that depends on the hardware underneath.

IMNSHO if it needs that level of isolation, build a tiny alpine install, 2 cpu & 1G RAM, 1-2G disk, and run the application. Why invent a new wheel?

8 bit overflow

Adding 1 *might* overflow to zero. IPV4 addressing was designed so one could do things like (inet >> 8) << 8 undocumented in your code. Then again the last shifted bit may reappear and bite you in the *ss. Overflow is overflow. The result generally by definition is undefined. Something about engineers programmers, bridges, and programs comes to mind.

I'd notate it as 000 000 000 000 0000

Re: Addressing only the problem that v4 has?

I mentioned this as well. Basically you enhance the existing ipv4 stack to recognize a packet that has a 64 bit ip address and 32 bit port number.

Internal rfc1918 space or existing spaces don't notice, their address is just stored in a larger bucket. But nooooo.

Re: I've said it before and I'll say it again

You can't put 256 in an octet, becuase it represents an 8 bit value 0-255 within a 32 bit . 256 does not become 0 via overflow, it is illegal notation. You can substitue a true DECIMAL value behint a URI http://4096 = http://0.0.16.0. An ip adress is a 32 bit value displayed as 4 'octets' 0.0.0.255 + 1 = 0.0.1.0. 255.255.255.255 + 1 = OVERFLOW. The resilt is not defined. This Nomenclature was done for readability. IPv6 is somewhat more arcane. Maybe we should have used BCD values/maths instead.

Re: I've said it before and I'll say it again

Not really too simplistic. 128 bits is just too long to grok by mere mortals. Adding in hex nomenclature vs dotted decimal, and it goes totally geek. Then start leaving out the middle if it's 0 and it becomes unintelligable gobblygook to the help desk. There were some inherent security issues in ipv4, but they shouldn't have thrown out the baby with the bathwater. Making an ip address 64 bits and only using 5 octets to start an mapping ipv4 into 0.0.0.0.x.x.x.x like you would do say going from uh 32 to 64 bit architecture. Then hack the tcp header with a protocol marker that signifies a longer header, or some other mech, and you keep people from losing their minds.

The number is too long. . .

The shift from 32-64 bit CPU architetctures should have been a guide. But no, Itanium is much better than AMD64. From a raw technology aspect, it probably was, but completely re-inventing the wheel was not the worlds best idea.

I know I could redesign an IP4 header with a marker of some sort to trigger address mapping to a 64 bit address and 32 bit port number. IPv4x, short term use 6 octets everywhere with leading zeros, until the stacks and such grok the wider space ummm kinda like 64 bit cpu's did. BGP tables overflowed long ago, and ipv6 does not make that any better. Just like your phone number an IP address can be anywhere. keep the space tight to cut down on stoopidity. A tiered routing approach is not a super bad idea. Nonetheless assuming most backbone routing as /24 of 32 --> /40 of 48 Keeping a full routing table might require a rather large chunk of memory.

Re: HAZMAT suit please, nurse, gloves please!

-- "Of course you should earn less. You cost the health service a boatload extra in care that would not be needed if you gave up this asocial habit "

Whups . . . wrong on this one. I think smoking it terrible, but this argument holds no water. The cost of the cancer, or heart , or whatever puts you in hospice doesn't really change, whether you choke, uh smoke, or not. The problem is one assumes a non-choker doesn't need expensive medical care before they die. Unfortunately, ... The longer you live the more it costs for medical care. If you get cancer then die at 60 while you are still working you are pumping money into the system right up until your overly expensive final care. OTOH, if you retire at 60, and live to 100, the last 40 years you are not pumping much into the system, but your care costs steadily escalate as you get older and don't die then generally cost about the same the last year or so of one's life.

If you want to reduce overall costs per-capita, encourage people to smoke, overeat, and generally get in very bad health so they die just before they reach retirement, before they stop producing income to put money in the system. Um, er, well anyway don't smoke it's stupid.

A good programmer...

Can write programs. There is ramp up time to whatever language you are writing, but i've found that most all programming languages have the same constructs. There are some oddities that handle operations strangely (postscript, lisp?, forth) but they pretty much all have the concept of data stored in memory, operators, if-then-else, while loops input and output. I understand I'm not writing in C much any more, and RPG-II,III, Free, COBOL are more record and linear oriented, i don't miss them much either, but I'm failing to see any huge advantage in Python (Apparently columns are important again, and I need an SEU template), I just don't care for the syntax, and the need for RUST is just escaping me. I moved from C to PHP for most things, and I tend to weld a bit of logic in PL/PGSQL. Java has never really tripped my trigger, it's always seemed to me to a language with a library (class, whatever) for pretty much anything, that always delivers disappointing performance, and usually leaks memory if it runs for any length of time.

Back in the day . . . There was a full blown accounting program, double entry, reports, etc, written using Bourne shell, and standard system tools: sort, sed, awk, ... Code was pretty legible. I'm sure someone will enlighten me to the huge advantages of RUST and Python.

How does today's DOW compare at 10 year intervals?

Biggest companies are constantly in a state of flux, Again, if they drop the ball, someone else steps up. I still struggle with some of these social media giants. I personally don't use them much. Just a Luddite i guess. NVidia is pretty narrow. At present they are somewhat better than the competition, but AMD for one has the upper hand (If they can keep it) with the APU synergy. Intel has made drastic (and I do mean drastic) improvements in their GPUs, still not there, but they have smart people working for them they can leverage to keep those improvements coming.

Currently CPU tech is so commoditized it's becoming increasingly irrelevant at the consumer level. The sorriest laptop you can buy is still pretty good for most folks. GPU tech is starting to get there as well. The majority of workloads to not require running a game at 200fps. So we are increasingly talking about edge cases for tech improvement, cloud server farms, bitcoin mining, etc.

I'm currently running an AMD 3400G on a couple desktops. They are ridiculously fast for everything I want to do. The 5000 series stuff is even more better. Why not get ARM/NVIDIA to put together something similar with less power usage and equivelent performance. I'm still trying to figure out which competition is getting stifled by them merging. ARM architecture is already very dominant. What can they do combined with NVidia they can't do anyway?

KSM-AZ

So you are saying the ARM investors, are a bunch of tree-hugging nice people, who just want whats best for the world, profit be damned? They are obviously not looking for market dominance, because they love competition. Really? They've got Apple on board, AWS is fielding GRAVITON-2 cores in it's DC's, I'm not sure who is buying who really. YMMV

Re: This is Silly... There is plenty of competition in the CPU space

Oops, Been a while there 68050 or was it 030? I think. Motorola. Full 32 bit Big Endian.

To the MALI point, ARM owns much of the embedded markets because of performance/watt, price, familaity. But the ARM markets are fragmented, and everyone is basically dumping an arm core onto custom silicon, custom boot, custom support logic. There are plenty other fabless core designs that can be welded onto custom silicon. If ARM gets uppity it just wouldn't take that long to roll to something else. The compilers and such are there. There is plenty of non-arm embedded stuff out there.

Apple,Samsung, et al all have Iron Clad agreements for the core ARM tech. So if things stagnate there, they can keep going and migrate to something else as the next new thing in CPU shows up. MIPS did merge with Silicon Graphics after all, MIPS-3D exists. And VIA is still around. They have some reasonable GPU tech that could come up to speed. As INTEL is discovering, a small mis-step, hiccup in this business and you find yourself playing catch-up.

It will be fun to watch!

This is Silly... There is plenty of competition in the CPU space

ARM is not the only player in this space. They have reached some dominance in the low-power embedded world, but the bulk of the general purpose CPU market is still INTEL with AMD biting the heels. Apple is making yet another shift 65K to Power to Intel and now custom ARM but they could easily move back to Power or Intel/AMD, or adopt MIPS or up and coming RISC-V. All are viable architectures.

Nobody is designing fresh CPU architecture the their garage. AMD pretty much has a much larger footprint in the CPU+GPU space. I would expect NVidia to put out designs for Apple wedding their GPUs to ARM cores like the current crop of wildly popular AMD APU's, but with more emphasis on the GPU side. The latest MALI GPU designs are better, but still not in the same league as INTEL's latest, much less NVidia orAMD. If they can build the synergy, I think it would be good for competition, but maybe bad for Intel. These days it's more about the FAB's and yields. The designs get somewhat better spurred on by physically smaller, electrically more dense dies. Should be interesting

"Right To Work"..

Long, long ago, when I lived in NC, a video rental store (Not Blockbuster), was making it's employees sign a contract that stated if they were fired or quit they could not work at another video rental store (Blockbuster the intended target mee thinks) for a period of 2 years. They were talking minimum wage jobs here. I'm not sure what the laws were at the time, but I told the person not to sign anything so ridiculous. "Right to Work" laws were invented to address these types of contract clauses, that would prevent someone from working within an acquired skill set. Most people working minimum wage jobs, were not really experienced enough to understand the document, so they just sign whatever paperwork is thrown at them,

Unions can work well for skilled labor and were a great equalizer early in the 20th century to combat numerous rampant issues that would eventually protect workers from unscrupulous employers. This got out of hand in the other direction when union leaders started to become corrupt. Government employees should NEVER get union protection. It's the fox guarding the hen house problem. If you don't like your gub'mint job, and want to be in a union, quit, get some skills and get a normal job that has union support.

Loading boxes in an Amazon warehouse is not skilled labor.

Re: Politics, not Good

Wow. I find the downvote numbers incredible on articles that actually state facts, albeit with some sarcasm. I live near the border. These clowns currently in office in the US are frankly scary, and the BS going on on the US/MX border was actually starting to get under control prior to the current fools. I think the problem is people are trying to foment animosity by contradicting fact with fiction, and downvoting sane thinking.

Be that as it may... if you are a parent and you bring a child ILLEGALLY across the border, and we take it away, I think that is the parents fault, not the governments. Keep in mind, most of these people are generally NOT from Mexico.

What's Wrong with a Netbook?

I'm typing this on a One Netbook,One Mix 3. I have a OM-2 as well, and the original One Mix. I removed windows 10 and loaded Debian, because I'm geeky like that, but I ran the Win10 for a bit, seemed to be just fine. Tablet mode OK, etc, etc. If I could get an ARM with similar performance running Debian it would be on my list. Iff you want to tote a "Gaming Desktop" disguised as a laptop more power to you. With a fully functional USB-C dock, I snap in and dual screen the local 2560x1600 display with an identical monitor bluetooth KB and rat.

The 8100Y is a little light. They have a new i5 with 16G that would be interesting, but frankly this does everything I want with a form factor I can tote, and a reasonable keyboard. I also had several of the smaller netbooks, the HP and the ASUS to name a few. It's kinda more around general performance, and what you might want to do with the machine.

Texas cops sue Tesla claiming 'systematic fraud' in Autopilot after Model X ploughed into two parked police cars

Tesla's auto-pilot works flawlessley, Smoking cigarettes is good for you.

Really people?

First off I've driven a Tesla with auto-pilot. Anyone who would just let that thing do whatever it wants is an idiot, and shouldn't be driving period. Blaming inanimate objects for human failure and stupidity is not productive or legitimate. I cannot stop idiots from buying a Tesla, and I can't stop fools from smoking cigarettes. You don't have to be the Amazing Kreskin to know that inhaling smoke in your lungs cannot be healthy. You don't have to be an aerospace engineer to know that the enhanced driving features of a Tesla are going to have some severe limits. I'm not sure that *TESLA* hyped the tech as much as the press. At this point I seem to see TESLA continually playing it down.

I do like the lane assist features on my Niro EV, but people need to use things as intended. In the case of hazmat, "Using any product in a manner not consistent with it's labeling" can lead to criminal liability on the user. Having worked for a pest control outfit at one time, I can tell you this is item #1 in the training classes... and item #5 and item ... and the last item covered. If someone does not use a product as intended, that is not the fault of the manufacturer. Like smoking, by now if you are unaware of the risks associated with this tech,it's not the techs fault, it's yours.

Chrome & Malware

Chrome is an OS disguised as a browser. To this end. I don't have that many people in my close circle. Yet THREE (3) have had their saved passwords and/or google accounts compromised because of chrome over the last 2 or 3 yrs. I would strongly suggest not using the google/chrome password manager (I use keepassXC). I've also found that chrome even under Linux (which I use for my desktop), can get hacked into from time to time. I've had drive by web pages, install? stuff, start sending data to strange places, etc, etc, etc. We use Crowdstrike here at work, and I have PA firewalls. Some of the stuff I see coming from chrome browsers on various laptops is stunning. C&C channel attempts, etc, kill chrome they stop? Yea, I'd be clearing cookies and cache regularly, and restarting the thing daily. I, in fact, do that for all my browsers. YMMV.

I stick to Firefox. I trust google about as far as I can throw it.
