If you want to get technical, here is a quote from Wikipedia:
Also in analog connected picture displays such as CRT TV sets, the horizontal scanlines are not divided into pixels, and therefore the horizontal resolution is related to the bandwidth of the luminance and chroma signals. For television, the analog bandwidth for luminance in standard definition can vary from 3 MHz (approximately 330 lines edge-to-edge; VHS) to 4.2 MHz (440 lines; live analog tv) up to 7 MHz (660 lines; DVD). In high definition the bandwidth is 37 MHz (720p/1080i) or 74 MHz (1080p/60).
Even a hypothetical widescreen System E (the 819 line French system) would not be as high resolution as 720p due to its relatively limited 10MHz analog bandwidth.
The TV featured dual resolution capability, with the higher setting offering better resolution than 720p â" 819 lines.
Nice try, but "by today's standards, it could be called 737i with a maximum theoretical resolution of 816x737 pixels with a 4:3 aspect ratio (10Mhz * 40.8 / 1000 *2 = 816)" Now compare this to the 720p standard which is 1280x720 pixels and a much higher resolution.
On trusted networks, yes, perfectly acceptable. Any security measure is a balance cost and benefit, for a trusted network the benefit of encrypting passwords is none at all. All it does is adding to a sense of security, not to real security.
Right. Except that there is no such thing as a trusted network. The old idea that we don't have to worry about security once you are inside the moat is just that: old. It has also been proven wrong time and again.
Even on the big bad internet the chances of you password being hijacked by a keylogger or because you typed it into a 'Check these pics!!' page are way bigger then it being picked up by a network sniffer.
Internet keylogger? I'm not sure what that is, but the chances of either of those happening is nil when I never use clear text authentication for anything.
I fetch my mail from my ISP using POP and a plain text password. I trust my ISP to make sure their routers aren't hacked and aren't running all sorts of sniffers. If I wouldn't trust them that much I should not be receiving any email through their servers anyway.
I'm glad you trust every single person who works for your ISP to be nice, competent, and to never make mistakes. Can I assume that this trust also extends to all the folks running servers in your ISP's facility (or the datacenter where they rent space)?
And I'm not ignorant, I noticed those bruteforce attacks TFA is talking about in my logs before I read about it. Did you?
I'm not sure how noticing something in your logs has anything to do with your clear ignorance of security best practices, but whatever.
In all seriousness, thanks. It is this kind of foolish thinking (yes, please keep using clear text authentication), that keeps us real security professionals in business.
To add to that it begs the question, shouldn't any operating system/application be secure by default?
That is really the heart of the matter. "Security" is not some end state that can be reached, so it can not be there by default. Computer security is an ongoing process involving practices, procedures, and policies. It requires ongoing maintenance. Organizations that understand this have information security teams working full time. The rest have undetected compromised hosts that people are ignoring because last year they installed something to make it "secure."
I would argue that putting ssh on some arbitrary high port is in fact a bad idea. If for no other reason than you have given yourself the false sense that you have added some level of security. If you can't run ssh on port 22 and keep it secure, you are not making the situation better by moving to another port.
I don't use POP, and I only use IMAP over OpenVPN or a LAN. I think OpenVPN > SSL, and I can physically see all computers connected to the LAN switch.
...and you were doing so well, too! Why do people assume that "the lan" is some magical secure place? There is no such place. Treat all traffic leaving your machine as if it is on a public network. Otherwise, any vulnerable computer on your lan makes all the rest of the computers vulnerable as well.
Wow, you clearly know nothing of the history of the VCD. HINT: VCDs, while never very popular in the USA, continue to enjoy great popularity in other parts of the world, especially most parts of Asia (with the exception of Japan).
No it doesn't and it wasn't sold. Back then all domain names were free for the asking. The title should be "The first registered.com domain name was just sold."
While I don't agree with the parent's tone, I do agree with the sentiment. Most people don't want to learn anything. They don't care how it works. And yes, the Ubuntu forums are full of bad advice.
Also, I don't think the parent is talking about people like you or me. I like to learn how it all works and then use the easy automated tools. That way I can fix it when it breaks. You, I, and most slackware users are the people others will pay to fix things.
Instead of bashing Slackware, I just think of it as a distro for people who like manual transmissions, so to speak.;)
As for 64bit distros it is still hard to find a real use for them. At least in my environment.
I don't know what you do in your "environment" but I don't have a single server in the data center with less than 16g of ram and that right there requires a 64bit distro to use effectively.
I don't know about you, but from the earliest days the "box" was called "the computer." The computer + the monitor + the keyboard + the mouse, etc is called "the computer system."
It may or may not be a "bad OS" but it certainly is a failure.
Microsoft is all about making money. Vista is a financial failure for Microsoft. The business world is mostly ignoring Vista. It has a bad wrap with consumers.
It doesn't really matter if it runs as well an an Amiga. It is a market failure.
This has nothing to do with Open Source. The question should be "Should projects that give software away for free be obligated to provide support?"
There is plenty of closed source software that can be downloaded for free. There is plenty of open source software that can be purchased with support.
The answer, by the way, is no. Just because software is free does not mean that the makes of it are obliged to give you support. Support costs money. Businesses who use software (open or closed source) pay for support, either through a support vendor or in house talent.
Actually, there are other options. I used to work for an all open source company, and they used some web based accounting software to do payroll.
To say that any product is required to run a business is just silly. Companies existed long before the computer, the phone, or even the desktop calculator. Part of running a small business is being able to just make it work, because it has to.
what sort of incompetent morons are they employing?
Funny you should ask. I have had several recent jobs cleaning up after IBM consultants. I finally had the chance to find out what is going on. It goes like this: IBM keep their top talent hard at work on the big multli-million dollar contracts. For the rest, it is anyone they can get off the street.
I learned of this when I recently had a job interview with IBM. They had already signed a $2 million contract with a government agency to build a computational data center, but had no available staff to allocate to the contract. The interviewer was completely candid with me when I asked about why they would sign a contract they couldn't fulfill. He said it happens all the time and is standard operating procedure. They simply hire contractors as needed. I turned the job down.
Ready for the punchline? They hired a guy that I have worked with in the past. This guy has no prior experience working with the technology he will be deploying. He is a decent guy, but he will be figuring things out on the fly. He is the best they could do. He is being sent in as an expert consultant by IBM. Think he will bill more hours than someone with actual experience?
I recently asked a former customer of mine, who works IT for a large university, why people would hire IBM over a smaller company with more expertise. He said that as far as his boss is concerned, if you hire IBM and they screw something up, you are covered because you went with IBM. This same customer then went on to tell me how IBM completely botched a $1 million installation job at his university last year. They are in court over it.
If this guy had a good lawyer they should have audited all the work done by IBM and the qualifications of the people doing the work.

In this case, the inquirer is missing it completely. First off, if you are recording important 4 hour sessions, I hope you already have a secord camera that you used as a back up.
What a professional would do is have two cameras and overlap them. Then you can combine it in post as the grandparent noted.

Are you really defending the use of plain text authentication as an acceptable practice?
it's still a switched network, which means sniffing is impossible
You might want to do a little reading up on network security before making such preposterous statements.
