Having recently re-watched DVD movies of "Dr. Zhivago" (1965), "Woodstock" (1970), and "Imagine: John Lennon" (1988), I gained a lot of confidence I'm not simply a crazy old man in this new era. First, I've never owned a laptop or smartphone. I don't know why people wander around with wifi connected devices carrying precious info they want secure. Some day I hope somebody re-invents an actual mobile telephone I can use to call AAA if I get a flat tire. So I'll mention the obvious; Suse Enterprise and Red Hat Enterprise. I really think you and many others in this group are serious Linux experts and might benefit from professional distros. Last, I'll suggest the old fashioned "pull the plug" security strategy. If the precious machine's power is unplugged and the ethernet cable is unplugged, data is secure. Further, if your data is on a separate hard drive from the OS and you edit the file /etc/fstab you can unplug the hard drive until needed and then mount the drive using a secure root password. Ya, it might all sound silly simple minded. Freedom, love and peace from the green generation. gregrwm wrote: > as answers roll in i would love to also know whether the same aspects of > security can easily be achieved with *ubuntu. certainly drive > encryption and vpn can. i've tried various distros for various reasons > but when i'm derailed by something that doesn't work i end up back in > *ubuntu. > > > On Wed, Jul 1, 2020 at 1:30 PM Randy Clarksean > wrote: > > Anyone have experience with any of the supposedly "secure" Linux > distros out there?

Since the existing school model can't figure out how to educate in this modern environment, maybe some innovative Linux users can help. My perspective is shaped over a long lifetime. During the Sputnik scare the best students were given every opportunity less well funded school systems could provide. As schools devolved into zookeepers and adolescent bone crushing sports sponsors, academics collapsed. Trying to get teachers to teach computer programming on the Window 9X platform met absolute resistance while my kids were in high school. But as someone who once studied advanced science, I see great teaching resources broadcast on PBS. Even a current broadcast commercial channel called Quest is a great teacher. We can't abandon children, even if our contemptible politicians have.

Like everybody else here, you are smarter than me so I think about your comments a while. But I will say, I spoke with several representative of relevant big shots and made a few points. First, none ever heard of linux and its free open source sophisticated status. Also, none ever heard of Raspberry Pi, mostly made in England, costing about $50. So the political talk of online education is dead at conception unless somebody rakes out at least $billions for whatever the Chinese cartel cooks up. Or the big shots could learn a very small fraction of what this group knows. Sadly, as you imply, big shots are a dangerous breed. No school is just beyond my thinking.

Sometimes they are the best, most flexible tool available. OTOH, we need to remember that this is not always the case. OpenOffice/LibreOffice is a poster child of this situation. It still does not have a built-in remove duplicates function. Extensions aren't a reliable solution as they come and go. Remove duplicates is a very easy to use feature, accessible to users of many skill levels. It is found in MS Excel and Google Sheets. Yes, there are ways to create similar functionality via formulas, but nothing as accessible as highlight cells and click on a 'Remove Duplicates' button. A few web searches show users were looking for this feature back in 2010, and I am sure it was requested before that time too. >From the perspective of advanced spreadsheet users, the lack of something that works like the Excel Tables functionality is a big gap. This is a very powerful alternative to traditional Row#-ColumnX referencing. It allows for easier and more reliable analysis of datasets by making formulas, references more dynamic than is possible with traditional RC referencing. It fills a gap between traditional spreadsheets and databases (spreadsheet formulas and cells provide a more of a 'visual' way to work with data in contrast to SQL). --- On open-source issues: The issue with open-source solutions is not with the underlying architecture (MacOS, iOS, and Android are all Unix-like under the hood) or with the philosophy. The issue is with: 1.) presentation (UI usability, which includes how performance scales across various hardware and missing but basic features, and UI stability, which includes how the system behaves with runaway apps) 2.) hardware and accessory compatibility. IMO, this seems to be a noticeably lesser problem than in the past. Also, many accessory devices are manageable via browser-based UIs over networks rather than needed USB connections and matching drivers. 3.) Whether discoverable application software is available that can do *everything* the person regularly did while using the prior solution. Obscure, nondiscoverable software adds friction. Renaming software between every distro adds friction. Should users need to relearn the name of all their common tools for each distro? I have seen browers renamed, file managers renamed, even calculators renamed. Some things shouldn't be renamed. To get a person to replace an existing solution, the new solution must be equal or better than the old solution in every way that matters to that user. Or the person must be willing to accept whatever the compromises are with changing solutions. [I see parallels to how people evaluate moving from a gasoline car to an all-electric car. Moving to a short-range electric vehicle requires more compromises than moving to a long range Tesla Model 3 (which has Linux running its UI), backed by the national Tesla vehicle charging network. Network effects in real life.] --- On performance: My experience with Android is it does a very good job, on par with Windows, in dealing with processes that become very memory or CPU hungry. The systems tend to stay responsive (may lag slightly, but usable), and recoverable (task managers can still be brought up), even under extreme memory and CPU pressure. I have yet to find a desktop Linux distro that can do nearly as well. Chrome and Firefox both easily get into 100% CPU usage and high memory usage situations that I don't experience on Android or Windows. If anyone knows of a distro that does as good as a job at maintaining resource control and desktop responsiveness under heavy load as Android or Windows, I would love to hear about it.

My experience with Android and Windows is they both do a very good job in dealing with processes that become very memory or CPU hungry. The systems tend to stay responsive (may lag slightly, but usable), and recoverable (task managers can still be brought up), even under extreme memory and CPU pressure. I have yet to find a desktop Linux distro that can do nearly as well. Chrome and Firefox both easily get into 100% CPU usage and high memory usage situations on desktop Linux, resulting in nonresponsive systems, that I don't experience on Android or Windows. These situations are easy enough to hit that even novice users can experience them with only a handful of open tabs, depending on the sites open. (On the exact same hardware, Windows can run the same browser with the same or even more tabs and survive). With these problems, I find it hard to recommend Linux as a general purpose desktop OS to others or even use it as my own desktop as my daily driver. Linux seems to do okay when the upper bounds of the loads are well-defined and easily fit within the available resources. Does anyone know of a distro that does as good as a job at maintaining resource control and desktop responsiveness under heavy load as Android or Windows? I would love to hear about it.

Again, I'm quite a Linux computer bumpkin, so I'll just share my experience for your feedback input. I use openSuSE linux, both 32 and 64 bit. My wife's laptop is 64 bit Windows 7, I have a Windows 7 32bit somewhere, too. The Windows 7 64 bit is all but useless, even after an expensive repair. My 64 bit openSuSE boxes mostly sit turned off. My web client machine (this machine) is an old core2 duo 32 bit 4gB ram running openSuSE 13.2. My development boxes usually just run openSuse12.2 32bit with similar hardware. The linux desktop was quite a pleasant surprise for me. I usually run 10 virtual desktops, sometimes use a virtual terminal. This all runs with KDE or XFCE. I like XFCE because I can have dozens of open NEdit text editors organized and stable. Currently, I'm enjoying learning ever more about Tcl/Tk after over 20 years. The KDE desktop installs with crazy amounts of "eye candy" and even has an "Activities Manager" adding yet another dimension of UI, most likely intended to fool your boss by quickly switching from playing to working. I usually unset the eye candy and set the OpenGL off and use XWindow rendering. The only time I run a bunch of browser windows is on eBay or programming language HTML manual pages.

Just a few things. First, perhaps making the swap partition larger is helpful. Perhaps a large memory video card helps with some uses. Perhaps using a memory tester to find a needle in the haystack. I've had some web sites really bog down, but I've heard the same from windows users. Sometimes I get a "script not responding" browser warning. Since some web sites love to punish you with advertising and tracking after they detect your OS and browser. Perhaps you should consider Linux browsers locking up a positive, not negative, feature. Firefox has a running report how much it has blocked, and it's a lot. Some fun chatter with a fun computer explorer here. I found Windows ME with an NVidia TNT2 video card has great 1600x900 @60Hz graphics on the modern displays. I have played with FreeDOS, Borland TurboPascal, and QBasic, etc. Also, the Atmel AVRStudio 4 is a wonderful tool to learn microcontroller assembly language. Just never let Windows ME touch the internet. Further, tk text widget GUI control can choose the blinking insert cursor to be a square block or line, and even how fast it blinks. As if it matters. I run into farmers all the time bragging about BIG tractors, BIG land, but they don't mention BIG BIG DEBT. Same with many of today's punk kids with multi terabyte hard drives who must expect to live 500 years to use it all. Thanks again. And please keep sharing your experiences.

Browsing webpages needs gigabytes of RAM today. I do not know how software development has got to be so irresponsible... I do not remember who it was who intentionally gave slow computers to their programmers to make sure they wrote efficient code. No such thinking today. I think it is a market-oriented problem; components are cheap, RAM is cheap, and all trouble stems from that. I will stop ranting about this now. I think that there are some bad design choices on the software side, like relying on other components that bring their own latency, memory needs, and problems to any one large software framework (say, Open/LibreOffice). I can think of the dreaded dbus. Also, try running two separate firefoxes at once under the same UID. But there are ideas. Controlling resources is a thing, and I think that "containerizing" execution may help here. Appropriate resources can be allocated per process, with caps on CPU time, I/O, etc. I do not know how to do this off the top of my head, but if there is an OS that should do it well for you, Linux is its name. Does anyone have a solution of this kind to offer so I do not have to do endless browsing for it? Very interested. It is hard to force open-source developers to do you the favour and make their software lean and robust to beyond what their testing suite extends. The response to this is: "here is the code, fix what you do not like". From n0nas at amsat.org Sun Jul 26 14:31:56 2020 From: n0nas at amsat.org (Doug Reed) Date: Sun, 26 Jul 2020 14:31:56 -0500 Subject: [tclug-list] tclug-list Digest, Vol 187, Issue 7 In-Reply-To: References: Message-ID: I've been using Linux full time for 5-10 years now but I'm not a power user. My main complaint is that Firefox uses more and more RAM for web content buffers the longer you keep it open. My usual thing is to keep it open and running for a couple weeks at a time until some accumulated updates force a reboot or the system hangs. After a few days start, when the web content buffers have filled most of RAM and started to fill the swap file, new programs have longer delays loading as Linux has to shuffle memory to make room. This takes some amount of time even with a SSD. If I reboot or kill the web content processes to release the RAM, the problem is solved until they fill up again. I had similar problems "way back when" with Win XP and Firefox. At that time it was the web page buffer holding Internet images that grew too large. I never had a lot of memory at the time and the web page buffer grew to over 300MB and searching the buffer took longer than downloading a new copy of the file. The problem was solved when I forced the max buffer size to 30MB. What I'd really like would be to do a similar size limit on the current version of Firefox.

My experience suggests it is on the web server side. The status bar on firefox shows connections with dozens of other web servers just to load what seems like a simple web page. My seamonkey browser still has the old fashioned blinking "stop" button on the toolbar, and downloading a web page these days seems like a long lasting busy connection. I even get grouched at by some sites for using the ad blocker; they say "how do you think we make our money, turn off your ad blocker." They even provide a button on their grouch box to turn the ad blocker off. Most financial transaction sites advise to close your browser after logging out. Not a bad idea. Like washing your hands.

(That is not an excuse for Linux, though, as Linux distros are mentioned as a way to extend the life of aging hardware.) The problem is we don't have much leverage over websites. Simply blocking all scripts also breaks the sites. Alternative sites aren't always an option. I myself prefer web 1.0 over web 2.0 and its heavy scripts, wasted screen real estate, endless scrolling webpages, poor contrast UIs, and other lousy design 'features'. There was a time when a Pentium 166 MHz with 64 MB RAM was enough for web browsing.

If you simply search "android google" a reference pops up https://en.wikipedia.org/wiki/Android_(operating_system) that says; Android is a mobile operating system based on a modified version of the Linux kernel and other open source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. If you go to the web site https://www.android.com/ you are immediately asked to agree to google cookies. If you want to eat google ad services and google cookies all day on a google designed phone I have no reason to try convince you differently.
