One aspect of my job is designing and building large-scale storage systems (often known as “SANs”, or “Storage Area Networks”). Typically, we use a tiered approach with SSD’s and HDD’s combined. That said, each one has specific benefits. SSD’s almost always have a higher Cost-per-Byte. I can get 10k SAS 4kn HDD’s with a cost-per-gigabyte … Read more
To liken it to a car analogy: A taxi can do over 500,000 kilometers before it needs an engine rebuild. The reason for this is because they are always running, 24/7, and after a car’s engine is up to temperature, the amount of wear it receives while it is running is greatly reduced. A computer … Read more
This is going to be a function of your workload and the class of drive you purchase… In my server deployments, I have not had a properly-spec’d SSD fail. That’s across many different types of drives, applications and workloads. Remember, not all SSDs are the same!! So what does “properly-spec’d” mean? If your question is … Read more
The general consensus seems to be that the answer to your question comes in two parts: How do we find the source of the funny burning smell? You’ve got the “How” pretty well nailed down: The “Sniff Test” Look for visible smoke/haze Walk the room with a thermal (IR) camera to find hot spots Check … Read more
Software threads are threads of execution managed by the operating system. Hardware threads are a feature of some processors that allow better utilisation of the processor under some circumstances. They may be exposed to/by the operating system as appearing to be additional cores (“hyperthreading”). In Java, the threads you create maintain the software thread abstraction, … Read more
Byte: Today, a byte is almost always 8 bit. However, that wasn’t always the case and there’s no “standard” or something that dictates this. Since 8 bits is a convenient number to work with it became the de facto standard. Word: The natural size with which a processor is handling data (the register size). The most common word sizes … Read more
Probably you are looking for a programmable microcontroller. If you have experience in C/C++/Java, checkout Arduino. Its chip is programmed using a C like language. This “How tos” page might help you get started. There are also some good books that will help you move forward: Programming Interactivity. Making Things Move DIY Mechanisms for Inventors, Hobbyists, and … Read more
The short answer is “no”, there is not an easy or standard way to do this. What you are looking for would be a Bluetooth repeater. Bluetooth repeater devices do exist, but are proprietary, not standardized. For example, this one from a German solar power manufacture, specific to their devices. Usually, Bluetooth networks are a … Read more
