Year of Linux on the desktop creeps closer as market share rises a little

vincent himpe

Re: what runs on the users machine

Yes and no. The cost of developing these things is staggering and the user base too small. Silicon tools have always been rentware.

Others like Solidworks and Altium are not rentware. They keep working but are frozen in time. You pay a subscription to keep getting updates, new features and bugfixes. Maintenance essentially.

You don't lose your work. I have a 3 year old license of Solidworks. It still works fine. I don't need the latest and greatest. Same for Adobe Creative Suite. Altium is the same deal. It keeps running but is frozen in time. That one i keep up to date as i make money of it. Silicon Design tools are true rentware. Stop paying and it stops working. This is akin to silicon testers where you pay for "test time" : you pay by the hours the machine is running so it is in everyone's benefit to test a given component as quickly as possible.

Re: what runs on the users machine

You clearly have not read my post. Try running CAD applications like Catia, Solidworks, NX , Altium and the likes. That doesn't work over remote desktop or on Wine. Adobe tools ? Rhino ? Anything GPU intensive with realtime 3D doesn't work over a remote desktop or in a browser.

The funny thing is that, traditionally, heavy CAD was always *NIX based : HP-UX, Solaris, Irix. The only ones remaining is Cadence and Mentor, although the PCB tools also have gone windows.

The remaining (commercial) Linux based tools are VERY picky on what distro. Mainly only specific versions of RHEL. Try it on anything else and you get no support at all. You are on your own, don't complain if you encounter issues. You can't do work like that. you are spending more time second-guessing and fixing the apps than actually doing productive work. Application users are not coders or sysadmins. That's a different world. There it DOES work. Outside that realm : not so much.

The Linux desktop ecosystem is simply too fragmented to cover all ifs, thens and buts. Every UI is different, using different runtimes and different libraries. They don't even use the same install mechanisms. Patch and Break. The application manufacturers don't want to deal with it. Windows is easier. Most windows applications are version agnostic. There may be a minimum version but that's mainly it.

The same is true for browser based apps. Remember the misery with having to make websites that could work in IE, Mozilla, Chrome, Opera. For many years you had to code HTML differently and detect the browser used. Fortunately that has mostly gone away. Almost every browser these days uses one of two cores.

Re-unify all the linux UI's around a common core , and have one package installer. That way anything can install anywhere and run anywhere, just like Windows and Mac.

But that goes against the grain of the entire Linux world. And that is the issue. It is too fragmented and too hard for the app developers to support all permutations.

Please don't start about source or open-source. The source of these applications is not available and never will be. And the knock-offs are not the same. Similar isn't good enough. Data exchange and translation are a forever headache and time-hog.

The (desktop application) business world doesn't work that way.

Linux has its place. But not on the desktop. Not until they solve some base things : making sure the existing apps can run. I understand that from a system admin perspective linux has certain advantages. But the desk worker has nothing to do with that. He/She needs to be productive. They have nothing to do with the OS. The OS is only there to run applications and access file systems over a network. We will run the OS required for the application pool needed.

Re: Applications that, often, only exist for the microsoft

That's the backend. i'm talking front end, that what runs on the users machine. Linux is fine ticking away in a server room somewhere. User facing ? Not so much.

vincent himpe

Re: Repeat after me:

Would that be : the ability to run EXISTING APPLICATIONS without hassle ?

Businesses don't use operating systems to do work. They use applications. Applications that, often, only exist for the microsoft operating systems. There may be "similar" applications but they are NOT THE SAME. Retraining the workforce , changing business operations. Not going to happen.

I'm in the technical domain. Catia, Siemens NX, Solidworks, Altium and lots of other CAD. sorry bub , windows only ... Running it under Wine doesn't work.

Re: there are plenty of alternatives to Windows 11 out there

I tried Wine. Doesn’t play nice with CAD aplications like Solidworks or altium. Same for things that need parallel port access (yeah i have several device programmers that still run off a EPP port so i need to keep some machines around with an ich9 or old style pci slot.). Wine is not emulation, it’s also not complete.

vincent himpe

Re: there are plenty of alternatives to Windows 11 out there

Ok. So recompiling the source is required. Any idea where i can get this “source” for Solidworks, adobe illustrator, altium designer, rhinoceros, dataman and hilo programmers and all the other software i use ?

I think you can see where this is headed : nowhere. There is no “alternative” to windows cause you simply can’t run applications. Switching applications is not an option. I’ll stick to windows 10 for now. All my software runs fine on windows 7 or later.

vincent himpe

Re: there are plenty of alternatives to Windows 11 out there

All the programs i use are 64 bit. (none will run on 32 bit versions like XP or 7 in 32 bit) .

Re: @vincent himpe - there are plenty of alternatives to Windows 11 out there

i only want to change the OS, so i don't need Microsoft anymore. I don't use any Microsoft applications (no office) , only their OS to run applications built by others. The file browser is about all i use from the OS to do basic file operations like moving , copying , renaming.

vincent himpe

there are plenty of alternatives to Windows 11 out there

Can i bring my existing set of application binaries and/or and installers ? I'm interested. This would probably interest many other people too.

I keep hearing about these alternatives a lot, but i must be looking at the wrong ones since i can't run any of the applications i already own. Please help ?

Re: Let's go Brandon.

i happen to live in such an area. (Behind yosemite : Madera) The only grid is the electrical, strung from wooden poles (that get hit by cars and at least one a year there is an outage.) Own well, check. own septic, check. propane? have a tank. Cell phone ? spotty at best. The "denser" areas have comcast (tv and internet) and that is your only option. even ADSL is not available. you are lucky to get POTS. The only internet options are Hughes net (very expensive and 10mb/s if you are lucky. if it rains: adios internet) or the newer mobile internet over 5G ( that also raises lots of protest .. ooh 5G we're all getting irradiated and tracked) and that is also spotty (see cell phone coverage). It's all farmland and homes as spaced very far apart and in clusters of 2 to 10. So starlink would be perfect. Have one access terminal and share with neighbours. Starlink has the ability to do that.

Re: Encoders

and how many supercells are there in the pack ? not thousands.

Again , i can't speak for every manufacturer how they do it. I only know how the ones i worked for did it. I've worked on several, for cars, space (launcher, rocket and payload) and aircraft. Same for the encoder. You can use contactless encoders that sense the magnetic field ( not hall ) . Use rogowski coils for current and melexis field sensors for rotation. I'm well aware how BMS systems work. . Matched cells in a supercell, each individual cell bonded with a fusable wire. If the cell shorts or is mechanically damaged the fuse will blow and the cell detaches from the pack. Voltage does not change but the max current does. During charge the cell voltage will climb faster for this supercell and the load balancer will kick in on this supercell first. This gives you feedback of how many cells are lost in the supercell. There are techniques to determine the overall state of the chain.

Re: Encoders

Some technical information to get rid of misconceptions:

1) Encoders are not used for rotor position (for exactly the reasons you mention : slipping. The three phase motor has a PWM drive mechanism using half bridge topology. A hardware block monitors the current in each winding. The hardware can predict, based on the currents, when the magnetic field will cross a pole. For a very short time (called the commutation window) the PCM drive to the winding is stopped by tristating the H-bridge. A voltage comparator checks when the polarity of the back-emf changes. At this eact point the rotor has passed the winding and commutation in the H-bridge resumes.

This is nothing new. It has been done in harddisks for 20 years. It's called a torque optimiser. No need for magnet sensors, magnetic couplings.

It used to be you needed access to the center tap of the motor but there is a solution to create an artificial center tap using a resistive bridge and some sample and hold amplifiers.

2: There is no thousands of sensors in a battery pack. i can't speak for all batteries but the ones i know of have only a few tens. the heat gradient over short distance is not large due to the thermal conductivity. Also the cell topology not a parallel lump of strings. you would lose the stirng if one cells goes out or if the fuse blows. They are a single string- of parallel cells. more like a heavy chain. each cell has its own fuse in the form of a bond wire. if a cell gets damaged the fuse will pop and the cells isolates itself from the parallel bank. In practice they use banks and chains made from banks. if you make strings of individual cells you would lose the entire string. if a single cell goes out in a bank the rest of the bank still works and does not interrupt the string so you don't lose the string.

The battery management system can sense the loss of cells in a bank and instructs the balancer circuitry to take this into account.

Long ago, in a design center far far away .. (chip design that is. running on Calma and ComputerVision systems driven by a Data General Nova . this is late 80's)

One day we found that the computer running the workstations had rebooted. Shruggingly written off as a one-time event. A week later the same happened. And the week thereafter and the week thereafter ...

Every thursday morning we found the machine had restarted. Strange. Service was called in and they couldn't find anything wrong. It couldn't be a scheduled job : the thing didn't have a clock or a way to schedule things. Files were saved with a version number that incremented upon every save. No time/date stamp.

Next thursday the sysop stayed late to monitor the machine from his desk in the aquarium. This was the era where the computer rooms were all floor to ceiling glass walls so you could proudly display the hardware to visitors. We users called it the aquarium. The sysop always said the fish were on the outside.

Somewhere late the cleaning crew for the office got in and sure enough: one of the cleaners entered the "aquarium" and started dusting. The nova machine had a nice ledge with a bunch of toggle buttons. out comes the dusting brush .... and mystery solved. It turned out there was a problem with the machine. One of the toggles was a halt/reset and it was a bit "sensitive". They replaced that front panel , and then put a piece of perspex over it, and told the cleaners to only collect the printouts but not dust anything in there.

Note : if i remeber correctly this things was a Nova 3

More than 4 in 10 PCs still can't upgrade to Windows 11

vincent himpe

Re: Nothing much against Win11 but can't see the point!

Os's don't have any value. The programs that run on it do. The OS is nothing but a layer between the hardware and applications , manages memory , storage, peripherals, a user interface and connectivity. Most of it (except the user interface) is invisible.

A perfect operating system would completely stay out of my way, let me run the applications i need, keep my data secure ( not only from external influences but also from hardware failures). It would eb invisible, need no configuration and just work. Windows 10 Enterprise comes pretty darn close.

I use the OS needed for the task at hand. I run NX, Solidworks, Altium and a bunch of other CAD and technical software. Windows. 7 year old Zbook G3 Win10. works like a champ.

I surf the internet , do online banking , create some videos and edit some photos : MacOs on a Mac ( a used one, 2015 model)

Phone ? that's for making phone calls. (and email / text if really needed, or the odd quick picture)

Windows 11 ? no thanks. Both my laptops are not able to run it. Don't need it, the applications run fine on 10. They even run on 7. So until the performance really becomes sluggish , or the applications absolutely need 11 , there will be no hardware upgrade. And if there is an upgrade to new hardware, by then there will be machines available that can run it.

vincent himpe

Then we'll talk.

Linux on the desktop works if all you do is browse the web, write letter , dabble in spreadsheets, and email and some video conf. Code writing and developing for linux will work fine as well.

Step outside that and its crickets. Heavy cad (mechanical , board design , electronics) , development tools for fpga and processors, debuggers, emulators, tracers, test equipment . It's windows and windows only. You may find some niche stuff but you are shortchanging yourself if you go that route, those tools are not up to par with the real thing. The industrial stuff is all windows based. and that stuff does not work well under wine or even in a virtual machine. CAD heavily relies on workstation grade graphics cards like Quadro's. You don't want layers of foreign software in between. Quadro's are bought because of their specific drivers for the high-end applications.

Re: About The Email Store-And-Forward Process....

email should be text only..

We need a universal dataformat that is non-executable . Allow only letters, number and punctuation. Subset of ASCII. ASCII is 8 bit , by suppressing more than half of it you cannot emulate opcodes even if you were able to break the system and manage to convert the data to executable.

The receiving routines would have a bitmask: anything not in the allowable set is simply removed from the input stream before it goes to the applications.

Then bolt an HTML or XML like structure on top of that to do formatting. Everything in plaintext.

Executable files can only be transmitted using a dedicated service (similar to an app store) and installed by an installer program.

Operating system is not able to accept any executable code unless it comes through that channel. That way you can plaster the users screen with as many warnings as needed to get it into their thick heads that they are going to install executable code.
