On our previous MicroSD shootout, Netac’s offering was deemed as the best MicroSD card for smartphones and compact cameras due to it’s low cost per MiB and very decent read performance. However, write performance was underwhelming, landing on the middle of the pack. It was with great surprise an high capacity, high performance MicroSD card from Netac landed on my desk: the Netac P500 Smart Card UHS-I U3 128GB MicroSD card (brands need to try to shorten the MicroSD product names, this is getting ridiculous….). This card corresponds to the fastest and highest capacity offer from Netac, supporting UHS-1 U3 speed …

There are currently two industry groups fight for market standardisation what regards to HDR: UHD Alliance and Ultra HD Forum. Every time this happens is usually due to a fight over consumer awareness on something that doesn’t make sense. We’ve already seen what UHD Alliance brings (or doesn’t….), but know there is a new group trying to make your mind: Ultra HD Forum. A lot has happened for last couple of years in the TV industry due to fuss around Ultra HD, always surrounded by confusion, mishaps and all around caos and damnation. How we got here Starting with the availability of …

Although I’ve been an Apple heavy user for a number of years now, it always bugs me when companies misrepresent their products, event if the misrepresentation is a underrating of the actual product. For me, specifications must be as accurate as possible, no matter if it comes from Apple, and understating it’s video decoding capabilities it not on my list of expected weird things, but it does seem to happen.

After having reviewed a number of different microSD cards, the next step could only be compare then over a number of perspectives, each of them making sense to a significant number of users. Now, I believe it is quite obvious for everyone that there isn’t probably a best microSD card but it really depends on which parameters, or ratios between parameters are relevant for each one. Each of them will then represent an important benchmark by itself, so let’s detail each of them: Read Performance – The basic SD card benchmark, and targeted by most manufacturers.

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.

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.

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 …

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 much success, my last attempt was with Memcached, and the results are stunning: On …

EDIT: This procedure is working as of ownCloud 7.0.2. Both QNAP and ownCloud have evolved since the lat updates, but some of the news aren’t exactly good: QNAP no longer supports customised apache config files; ownCloud 7 updater removes any unknown files from onwCloud root directory. How to fix both? Well, as for number one, there’s no good alternative, but it can be altogether worked around. As for number two, the fix (and workaround for one) is the following: edit .htaccess file present on ownCloud root dir, and add the following lines on the <IfModule mod_php5.c> tag: php_value eaccelerator.enable 0 php_value eaccelerator.optimizer …
