Glad to see that you solved the issue. Hyper-V is picky on the NICs; I had to exchange cards and update firmware several times on production servers to solve all kinds of strange networking behaviour. My Windows developement servers are mostly old hardware with random NICs, so I install VmWare...

If the drive does not power up, the culprit is almost always the "combo" power chip, on this drive is marked TLS2505. It controls the spindle motor, voice coil (VCM), and the two Vcore and Vio buck regulators. The PWM controller, MOSFET chopper, and Schottky diode are inside the package. It does...

VmWare Vsphere with the FT (Fault Tolerance) feature enabled does this, but it is neither free nor cheap or easy to deploy. The cluster approach is more simple and cost effective. As added bonus, the secondary server of the cluster does take a portion of the load from the primary one; On a FT...

It's just another proof of the long-time Oracle attitude towards their customers. This is not even the worst one, they are used to sudden increases of maintenance fees and to force-buying unnecessary services. Some Oracle software is technically good, but the rentless exploitation of vendor...

The lease/own choice isn't so obvious. It relates to fiscal policies and to cost of capital acquisition. As general rule, leased equipment is more expensive. Leasing is like a credit card: easy to get, convenient to use, but hardly the cheapest way to borrow money.

Good SSDs fails far less often than mechanical HDD. In 2 years I had only 1 drive fail (100 deployed devices - it was a firmware related failure). There is a popular alternative solution: install a second, independent drive and schedule a periodic rsync from the primary one. If primary drive...

You need both a 802.11ac router AND a latest generation Wi-Fi card to get high performance from a wireless connection. Be aware that the 5 GHz range is shorter than 2.4 GHz; a performance decay over a brick wall is normal. Don't worry about the Wi-Fi radio emission, it is very low. According to...

This is a interesting comparison between two houses with a very different energy profile. Let's go a bit further. The monthly breakdown of my electric power usage: KWh 132 - march 2014 KWh 123 - april 2014 KWh 166 - may 2014 KWh 127 - june 2014 KWh 197 - july 2014 KWh 204 - august 2014 KWh 164...

My current annual electric power usage is 1718 KWh; monthly average is between 120 Kw (winter) and 200 Kw (summer - due to AC and increased use of the washing machine). The apartment has been built in 1993 and I got a tax bonus in 2010-2011 to refurbish it with energy efficient technologies. I...

I still use several RPis at work, there are two dozens in production now. The latest additions are: quad-view monitor replacement for videosurveillance (on lobby desks) - they display 4 mpeg streams from IP-cameras on a repurposed 19'' dvi computer monitor. The backend is ZoneMinder. RDP thin...

I tried the Olimex A20-OLinuXino-LIME 4Gb  last year, but I was disappointed by the poor quality of the Debian-based Linux distribution. Many packages are missing, HDMI monitor support is basic and it cannot even boot from the embedded Flash, Linux must boot from the slower Micro-SD card. I will...

I use mostly Ovh (I have about 60 domains with them); and Inwx for the "exotic" TLDs. For the few important domains I subscribed a managed service with the local Dada.eu company on my country. Any change on the control panel is manually verified by a agent that knows me and my authorized...

The RPi2 behaviour is not uncommon at all. If you go around any live, unshielded consumer board with a EMC immunity tester, malfunctions or faults are the norm. I know first hand because, when I worked as electronic engineer, I sometimes had fun torturing random portable electronics on the EMC...

I believe that 300$ may not be enough for a professional full custom metal chassis because the manufacturing of this kind of complex metal parts is a iterative process. You start with some technical drawing, then the machine shop expert will suggest modifications to build the part in a...

Try to minimize the number of foldings, because for low-volume production they need to be manually done by a worker on the press brake machine: a slow, expensive and low-precision process. Holes and straight cuttings will be done automatically and very precisely by a laser cutting or water jet...

RPi-TC is a nice project and the optimizations on the remote desktop clients are far more advanced than the stock Raspbian packages. I need a few standard Debian packages for the management script; and the Raspbian image already has the freerdp package. I will check again RPi-TC when it will be...

Today I used all day the brand new Raspberry Pi 2 as my main thin client desktop. We use a plain, cheap vanilla Microsoft RDP over Windows 2008R2 or 2012R2 remote desktop servers, nothing fancy or high-performance such as Citrix. I started with the Raspbian image, and I installed our in-house...

My experience is similar. I got the black friday free credit and I started to play with the control panel. I also was frustrated by instabilities on snapshot creation, ISO uploading and instance creation. Basically, sometimes you need to retry several times until it works (and it will work...
