1 in 5 VMware customers plan to jump off its stack next year

KSM-AZ
Go

What comes around goes round and round

The problem is VMware is alienating smaller customers. Over time smaller customers become larger customers who are not using their products, over time the free and less expensive products become more robust, and then larger customers start looking at the less expensive alternatives. Microsoft did this to the IBM, Sun, SVR4, mini-midrange-mainframe market, and we are going to see another cycle probably much faster with VMware, since the core of technology stack (Virtualization) is a pure software play.

"Under the rules, any electronic device priced between $50 and $99.99 would need to have parts available for five years, and devices that cost in excess of that would have to have parts available for seven years. "

Any electronic device priced between $50 and $100 should be E-wasted if it breaks. It's not worth $50 to crack it open.

Re: Out of space

The geek that was the DBA was fired or moved on. His assistant didn't really have a handle on everything but took over at 1/2 the Salary cost, management was happy. A year or so later the new guy realizes he's grossly underpaid, asks for more money, is denied, and finds another gig elsewhere. Clerk who always wanted to be in IT takes over, fortunately everything is in good shape so things continue to run smoothly even though there is not a good understanding of all the processes. Over time, minor changes cause a disruption, nobody with the skills to notice, and it blows up.

Or maybe, new DBA was hired to replace the guy who left, but has no idea the process exists, and nobody is complaining, and the error messages were being sent to an email address that no longer exists. . .

Or it was outsourced to India, and we are in the process of training up a 4th set of contractor folk who are going to leave in a year or so. . .

Re: NFS, worst protocol ever

"NFS is probably the only protocol in the unix world, that is worst that its Microsoft counter part.

It's always been shite, performance and reliability wise."

--Flame Bait--

If your trying to say NFS is worse than SMB/CIFS I beg to differ. NFSv3 performance is very good albeit single threaded. NFSv3 also works reasonably well over higher latency connections. SMB/CIFS falls over. That being said, Microsoft's NFS implementation is abysmal. If you are running a *nix box run NFS, If you are running Windows run CIFS, though both can be abysmal under windows. I've used NFS extensively since

I note NetApp still uses NFS as the core protocol for VMware storage connectivity, and it routinely out-performed iSCSI in years past. I know more recently they support multi-threaded NFSv4, though I haven't followed the benchmarks recently.

The reason behind the minimal consumption is thanks to recycled water.

I've got a pinephone. Thrown pretty much all of them on it. Ubuntu touch has the dis-advantage of not working all that well in general. Postmarket and Arch and Debian and the other projects are so much farther along,I think I'd put the effort in Plasma Mobile, or phosh which seem to be mostly working. What we really need are phone apps. Not effort trying to weld ancient desktop things on a phone display. Further the drivers for the cellular modems are still rather 'alpha' quality. We really need to figure out modemmanager and ofono and all the low level driver cruft is targeted at the latest kernels which need Linux 5.x. It's miles better than it was 2 years ago, but still pretty awful.

Re: De-duplication?

-- "It’s an electric plug. FFS."

No it's not. It's a Universal Serial Bus, that happens to have power on it to power remote devices. Always has since 1.0 5v at up to .25a. Just because the spec allows for everything, does not mean that the 100W PD brick you bought would implement anything beyond the charging conversation. And the arguments here about malware are borderline silly. If you use a USB-C hub with HDMI and ethernet they have to have drivers and such on both ends. I have updated firmware on a number of USB-C docking stations. I doubt that would be implemented on a power brick

USB is a BUS with some evolving standards around power distribution on the bus. You know like the power definitions on a PCI bus, or any other similar computer bus. We are talking about standardizing the connector around the USB-C connector spec. Just as the Micro-USB slowly became a 5V/2A "standard" for small device power and charging because it was ubiquitous so will USB-C supplant it being backwards compatible with tiny adaptors, while allowing for drastically more power. Arguing the esoteric's of a specification is just wasteful. We are already seeing stable ASIC's that just work, and the price premium for it dropping.

KSM-AZ

Re: De-duplication?

The market will make USB-C the standard without gummit' intervention. You don't have to carry around 20 different chargers today. Not so true 5 years or so ago. Further, the arguments are somewhat silly. First of all power requirements are basically much higher for the average device today. You can hop on amazon and buy some Usb-C to micro usb charge adapters for around US$5 in a 5 pak with a little chain you can clip around the cable. I don't think there are any non-apple mobile devices today that dont use UsB-C. For the handful of things that still use micro-usb the adapters work just fine (Samsung smart watch wireless charger for example).

Most of the current crop of inexpensive charging blocks are shipping with at least a mix of USB-A and C connectors and support PD. The last piece of the puzzle is PD on the laptop side. Dumping 100watts over the #28 and lighter wire, means the voltage has to go up to compensate for the lack of current. Assuming around 3A on #28 you should be pushing close to 35v to get 100W, without the wire melting. 'PD' aka Power Delivery protocols is what makes this possible.

Finally I have noted improvements in the physical connectors on both the male and female side. The last few cables i got seem to be much more 'snug' and secure when pressed in. YMMV

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: 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.

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.

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: 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.

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.

Yes, it is dangerous.

People are used to vehicles making a certain range of "moving vehicle" sounds.

----

I call BS. And the regulators are getting way out of hand. Why does my 2020+ Niro EV need a police siren loud beep when backing up? Because before I unplugged that bitch, if I backed out of my driveway at 4AM, every neighbor within a 1/4 mile knew I was moving. But yet that new RAV-4 and Jeep next door don't make a peep. Exactly what "moving vehicle" sounds does a modern car make? 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.

Modern ICE vehicles are QUIET. I would also note, that just like smells . . . We tune out familar noises whatever they may be. If you can stand here and tell me that you are over 30 and have not walked thru a parking lot and been 'surprised' by a car backing out, then you are either lying or lucky. Further if you tell me you HEARD IT BACKING UP, unless it was a Diesel truck or beater with a bad muffler, I ain't drinkin' the kool-aid.

Watch where you are going. ASSUME the car has broken backup lights and is headed your way.

Linux Snap package tool fixes make-me-root bugs

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 cut the GF over to Kubuntu 18LTS years ago. I am safe to say she has had ZERO problems "harming herself thru mistakes she has made". I'm here to tell you, for most home desktops 99% of the time is spent in a browser. Frankly the only reason Window's is still relevant, is because it is the path of least resistance for the manufacturers.

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. I've written more powershell as the Linux guy, than all of our Windows 'Administrators' combined. And I can't stand powershell. YMMV.

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? Build a better guest management and deployment framework for kvm/vmware/whatever. Quit overthinking the problem. Stop solving problems we don't have with a new idea everyone should use.

Snap is a bad idea

I'll say it again. SNAP is a bad idea. Appimage maybe. /opt/package, symlink startup, fine. I don't like 10,000 mounts of read only stuff plus directories of read/wite area, controlled in an appstore. If I wanted a Mac or Android, that is what i will get.

All AMD ryzen support ECC

Yep.... all of them. The 'PRO' models are 'certified', but all the cpu's work with ECC. Must be unbuffered ecc, not registered. And I've got a pair of 3600's running it, and one of them just started complaining about corrections about 2 weeks ago... So I'm gonna replace the RAM as soon as I scrounge up the 500 for a pair of 32's.

Note: Motherboard BIOS must also support it.
