Microsoft Teams Linux - Calendar Doesn't Work Missed Meetings!

For some reason this bug is only present in the Linux app but not in the Android App or from the web calendar. This is a horrible design flaw that ca........

How To Install python 3.4 3.5 and up on Linux with wine - Working Solution

This is sure simple if you follow the guide but it took a lot of hacking around to make this work on Debian/Ubuntu! Now before you ask why bother running wine and python, the reason is because Python executables are NOT cross-platform. If you run pyinstaller in Linux, that binary will only run on Linux and the same if you do it in Windows. So it is preferable if you have a single environment that you can create Linux and Windows binaries from rather than running 2 separate........

How To Boot Cisco CUCM UCSInstall 8.6, 10, 11 and 12 on KVM/Proxmox

The key thing is that you must use a "machine"id of "pc-1.3" or it will say your hardware is not supported. Additionally you MUST use a virtio disk or you will get a ks_pre.sh error as soon as the install starts (a look at logs will show it can't find a disk). This is funny because even though the OS finds the disk and an fdisk -l shows it, it looks like the script looks for a /dev/vda device (virtio) and nothing else, so if you didn't use Virtio as you........

What's Needed To Fix Linux

I really am a Linux fan but my comments here may not show it. Although I'm quite familiar with Linux CLI to administer servers, I find Linux GUI OS's like Ubuntu at times very clunky. This is partially because there's no such thing as a "self-made" Linux from scratch where the UIwas designed by a single team. Linux is made up of several different projects that are generally completely separate and this lack of integratiion is a key issue that makes things f........

How To Test If Your Hard Drive Is Good/Signs of dying hard drive

I like dd, although it only reads it, usually a read test of the entire disk will uncover if your hard drive is bad in some parts. This is a good thing to do at least once a month, a lot of times bizarre program behavior, laginess and crashing/unnmounting problems etc.. are due to a failing disc and SMART won't know it or indicate a problem: We must also remember there's never a guarantee, I've found that ever since we moved to larger and more platters per drive with 1TB drives........

2011 Best Laptop - HP 15.6" Laptop featuring AMD Athlon II P340 Processor (G62-420CA)

My mother needed a new laptop and I recommended her the same one I would have bought myself or my wife, that means the cheapest possible laptop with the most features for the money. This HP shines at this price point and one thing that made me stay away from buying more and recommending HP/Compaq was the poor battery life. Not anymore, this model has an industry leading up to 4 hours of battery life. Key Factors for Choosing It: HDMI Out........

Ubuntu 10.04 Linux is still not ready for the Desktop world

I am a huge fan of Linux and the idea of OpenSource but I've said it many times, there are still hurdles in today in 2010 for Linux as a Desktop. Linux is still intended for servers at its very core. This can be changed succesfully though, as Apple has shown us with Mac OS X based on FreeBSD. Half of the issue is lack of driver support and the other half is the Linux Kernel and Window Manages, KDE and GNome still both don't cut it (but they're getting closer). I'll........

Realtek r8169 1gbit/1000mbit NIC/Ethernet Goes Down/Halts on Large File Transfer/Heavy Network Usage

This is especially serious for those who are running servers with this chipset, who can afford for the NIC to randomly go off-line for no apparent reason?

XBOX 360 No Sound over HDMI Solution/Fix

My XBOX's dashboard/firmware was from sometime in 2008 when I first bought the system. I mainly played using composite cables but at my brother in law's house we used HDMI. The very first time it worked, but then I bought some games that did some update and after that HDMI never worked. The symptoms besides having on sound is that your XBOX will show PC monitor resolutions but won't have any option to say you have a 720P or 1080P display, this means the XBOX firmware is fa........

tar gzip: stdout: File too large - Error Size Limit on Large file > 17GB

The folder I was trying to archive is about 72GB, but much like rsync at about 17GB it chokes because of the filesize. What's with so many common and essential Linux tools having such limitations? I guess it is likely that the authors never wrote their code with the idea that files would be so large but it's still very annoying. It's important to stay on top of these limitations on production servers because I didn't realize what happened until I checked the file with "........

Codelite C++ IDE is a Cross Platform Unix/Linux (Mac OS, Ubuntu etc..) and Windows for C++ development

Codelite is a great choice and I intend on getting back into C++ development and I think Codelite is great being cross platform. It looks like it was designed with a lot of thought and should do the job better. I really dislike the bloated and confusing IDE's from big companies like Microsoft where you usually have to use .NET and other useless technologies that just give Microsoft the advantage over you, the programmer, and the users.........

Norton Antivirus is the worst - who would have known?

It does seem to be fairly full featured and somewhat straight forward, but like so many programs it is missing a few key features or things don't work quite right. It doesn't support importation of CSV files, which is a big minus. And the developers rather than wanting to add support have just dec........

iPhone/iPod touch on 3.0 software overheating?

There have been lots of reports like this going around and Ican confirm my 3GS with 3.0 firmware is overheating as well. It gets quite hot and actually can make your head or hand sweaty when holding it to talk, or simply holding the back cover for any reason. It's a wonder how the device cools itself at all, considering the only thing that could ventilate air are the 2 speakers at the bottom or the single speaker on the front of the device.

Why Apple should thank the jailbreakers and not patch/stop the jailbreaking exploits

First of all, the iPhone is crippled in many ways, but most of my complaints about functionality have been addressed through the jailbreak, Ican run apps in the background of my choosing, I can install a terminal, acccess my phone through SSH and SCP and so much more. It even addresses the 15 minute e-mail problem, I installed a program called "PushMod" and now set the checking time to just 1 minute. Apple should really thank the developers for this gift, it ma........
