It doesn’t manufactures any flash chips, or SD controllers, as Samsung or Micron, as so many other brands out there, like Kingston, Mixza simply resells products manufactured by 3rd party factories, or to some extent, packages all electronic components in-house. This specific MicroSD chip was manufactured …

New Secure Digital cards sport theoretical speeds up to 104 MiB/s, for UHS-1 cards, or even 312 MiB/s for UHS-2 cards. Now, those are only bus speeds, and actual speeds may be a far cry from it, but in some instances real performance isn’t that different. On the other hand, it clearly demonstrates need for updates SD Adapters, as those new Secure Digital buses require compatible adapters, and again, USB3 compatibility. Then, which are the use cases for an USB3 adapter? Well, unless you intend to use your SD cards to extend your laptop storage, for instance, using one these …

The emergence of micro SD cards, which are today pushing any other solid state portable format to a niche status, including ironically, the original Secure Digital cards, raised the need for decides designed to read such cards. On the the other hand, the actual microSD state of the art raised the bar for bandwidth to a whooping 104 MiB/s for UHS-1 or even 312 MiB/s as defined by the latest 4.0 SD specifications, means that old USB 2.0 readers both internal and external were not longer adequate to handle those cards, but instead an USB 3.x would be required. Of course, …

For those looking for a strait forward PKI, here’s how to get it, using Cloudflare’s CFSSL. Why CFSSL? If you’re looking for a simple solution, this is as simple as it can get: install Go Compiler, compile CFSSL and your done. Drawback? There’s little flexibility in terms or library versions. You get what Go offers. Now, CFSSL isn’t the most well documented application over there and yes, some configuration items aren’t document at all, so see right below on how to create a PKI using CFSSL. Editor’s Note: This walkthrough was corrected to support the new “ca_constraint” parameter.

Configuring an NTP server is by far not the most strait forward nor best documenting activities while managing a data center. Adding authentication on top of it, just makes things worse, far worse. Fortunately, it’s something only done once. The end goal: Authenticated NTP. ntpdate -d -k /etc/ntp.keys -a 10 your.ntpserver.com 9 Jul 23:24:33 ntpdate[19359]: ntpdate [email protected] Fri May 28 01:20:57 UTC 2010 (1) Looking for host your.ntpserver.com and service ntp host found : 13.3.150.148 transmit(13.3.150.148) receive(13.3.150.148) receive: authentication passed

One of the big news during CES 2016 was the announcement of UHD Alliance Ultra HD Premium specifications. However, all said and done, it was a complete disappointment as far as consumer interests were concerned. The end result is nowhere nearer anything which can be useful for a consumer to take an informed decision on which new TV set to buy. Why? To understand, one needs to spot the questions the UHD Alliance set out to answer, and where it failed, miserably and fully intentionally.

It’s been literally years since I (and others) requested Radmin to add Mac OSX to the list of operative systems supported by the client version of Radmin Remote control. Actually one can actually see posts requesting this feature back in 2005. So much for listening to user’s requests…. … Well, enough is enough and it’s time to leave the Windows virtual machine, and use Radmin on Mac OSX through Wine and all it’s native beauty. It take a number of hours, but at the end it’s well worth the wait. Install Macports This step is only necessary if you don’t already …

EDIT: For QTS 4.2 onwards use this guide which includes the right package.   For too long I’ve been struggling against my Semantic Mediawiki performance running on a QNAP machine. Pages were taking 10+ seconds be generated and new pages could take around 30s. Although those were certainly not the most simple of wikis, judging for the number of semantic properties and templates associated, those times were simply unacceptable, even for an Atom based hardware. After trying to improve QNAP’s Mysql performance, and upgrading to the latest available php 5.5 on QNAP (which already supports OPCache by default), all without …
