A lot of companies are unsure which solution to choose and many may not be aware of Docker Swarm as an alternative to Kubernetes. One thing that many Sysadmins find is that Docker Swarm is simply easier, quicker to setup and maintain by far than Kubernetes.........

ID3 2.4 can cause various MP3 players, especially on vehicles or even computers, not to play or at least not to display the ID3 tags. In many cases though, since ID3 2.4 is much different than version 2.3, it will cause some players, especially in cars like Lexus not to play. Even on the computer, you may notice if you check the properties of the MP3 that it won't open or show any details (eg. frequency, bitrate and ID3 tags). One symptom of this in a vehicle (eg.

I experienced this with CPanel's Exim after an auto-update (a Google of this error produces lots of complaints with few clear solutions). In this case I'll put the solution at the top.

I took an educated guess because it kept happening at the same spot when loading the XP install. I thought it was the hard drive or motherboard. But it turns out my heavily used but loved NEC 3500 DVD-RW drive was the culprit. After disconnecting it and swapping it for another much beloved Pioneer DVD-RW, everything has gone smoothly. I never ran into this or many issues because I've hardly used this drive since moving it to another Desktop years ago. I actua........

I have no idea why but mkfs.ext3 defaults to a patheticlly small blocksize of 1024 bytes/1KB (kilobyte). That means the maximum filesize is ONLY 16GB! With 2KB/2048 bytes you get a 256 GB maximum filesize, and with 4KB/4096 bytes you get 2TB! I finally noticed/paid attention to this after realizing that with rsync and scp that no file larger than 17GB could be transferred. I then realized it must be a file size limit on the partition. Here is what tune2fs tol........

Need identd for port 113 ? Install authdyum install authd Happy identing :)Actually it's not that simple. It installs as an "xinetd" service and is disabled and turned off by deafult. To enable it run: [code:1:8c94df8319] chkconfig --level 3 auth on service xinetd restart [/code:1:8c94df8319] This will set identd aka authd to start by default. service xinetd resta........

DVD Burners and Media at an all time lowThis is crazy you can buy a nice Pioneer DVD burner for like $64 CAD now and good media like 50PC Maxell is just $25.97 at Walmart. I'm liking this. Time to make double archives of important data :)........

Link Exchanges- Friendly AdviceI just wanted to make aware to the public who are paying to use Link Exchanges to get heavier traffic online and boosting their page rank in Google. Please be advised that this type of 'exchange' can very well get you booted off of Google and blacklisted by them! It's happened to many people and it's a very important tip. If you are on a Link Exchange, and have not been booted off yet; you MAY. Google is very smart and eventually they catch on. ;) Be ca........

As much of a computer nerd as Iam, I'm usually a late adopter to technology for a few reasons. Ifeel most new hyped technologies and electronics are mainly fads, and I'm also cheap. Adopting later means you avoid the bugs, kinks and most importantly pay the lowest price, that's me being cheap again :) I never read much about the iPhone but Isaw all the hype around it and until recently I wasn't a big fan of anything Apple until a few years ago I realize........

I've had an old Blackberry for a few years and I was ready to spend some serious cash on a nice Nokia. I love the idea of the Linux based Symbian S60 OS, so I was looking at phones like the E63, E71 (both are basically the same, at least CPU/screensize although E71 is thinner, has a 3MP camera, has GPS, and has dedicated buttons to adjust the volume). Then Iheard about the N97 and what a revolution it was supposed to be and it was even compared to iPhone. To........
