Comment Re:So why use these large cloud services? (Score 0) 161

Google is pretty much an also-ran at this point so the question is AWS vs. Azure (or of course self-hosting but we'll assume you really want to do cloud and I can't talk you out of it). In my experience the answer depends on your application. If you're building a new from the ground up web-based application AWS is probably the front-runner. If you're migrating an existing in-house system and want to do things more incrementally, do something hybrid with your in-house stuff, etc. Azure is far simpler to get that going with. Azure feels designed to be familiar and comfortable for traditional enterprise IT people, AWS feels designed by/for the Silicon Valley startup crowd.

That's easier said than done though. See for example the Amazon AWS status portal which stated things were just fine for far longer than they were because Amazon couldn't update it. Doing cloud based applications right is neither as inexpensive or as simple as a lot of people were led to believe/preached.

This. Clearly a lot of people jumped into cloud "to save boatloads of money" (same reason so many jumped into outsourcing. Saving tons of money is not often a good reason to do something. Usually you can make incremental savings but it's never what the salespeople or service promises because those prices ignore things like redundancy, etc. In the end doing it right ends up costing about the same as you were paying before, maybe a little less or a little more and maybe you gain some more features, but it's also probably more complex.

Comment Re:Wow AWS Goes down also? (Score 2) 161

I caught that too and thought it was interesting. One other interesting thing about an application that really uses cloud services to their full potential (rather than just as an expensive VM/VPS) is that since the services are not commoditized/standardized there is a lot of cloud vendor lock-in. E.g. if you build a huge web app around AWS you're going to have a lot of rework to do (to some extent depending on how well you modularized your code) to migrate to another cloud provider.

If you stick to Prime eligible products, you don't have to deal with the fraud as you're dealing with Amazon and not a third party.

Depends how you define "dealing with" Amazon is not always the seller, they are increasingly a logistics/fulfillment company and not the seller. While it being Prime does mean they have the product in one of their warehouses it absolutely does not mean you are buying it from Amazon. In many cases they are just warehousing products for someone else and they send you the product which has been barcoded by the actual seller when you purchase it. If you have a problem with the product you might soon learn that it isn't Amazon you bought it from, prime or not.

Comment Re:RS-485 (Score 1) 615

I'll assume you're not kidding and answer your question. Yes, of course people still use RS-485. It's not RS-232 over longer connections though, it's just a different type of serial driver for a UART interface (i.e. it is equal to RS-232 but handles the line driving differently). One such difference is the use of balanced A/B communication lines instead of +/- lines used in RS-232, which yes, gives it better reliability over longer distances.

Specifically the popular Modbus protocol runs over RS-485 and it's used extensively in industrial control systems. DMX, which is still used extensively in the theatrical/concert lighting world is also based on RS-422/485, though there are some differences.

Comment Re:Ham Radio? (Score 2) 177

Note that if you want to legally build RF electronics for experimentation that's a very good reason to have a ham license even if talking to people isn't your thing. For example if you want to experiment with 2.4GHz WiFi at power levels much higher than what's allowed for general public use...

Note, I completely agree about the first part of what you said. When describing any kind of portable energy storage to the general public it probably makes the most sense to refer to it as a battery. I disagree about the second part though, I would still argue that if there are multiple small capacitors it's correct to call it a "battery of capacitors" or perhaps a "capacitor based battery" in technical publications.

I beg to differ, chemical energy is not required. See the Oxford English Dictionary...

battery, n.

Note that TFS states that "The high-powered battery is packed with supercapacitors..." see the definition for battery responsible for why we call groups of electrochemical cells batteries... "a set of units of equipment, typically when connected together" which is based on the traditional usage for artillery batteries. So if there are multiple supercapacitors working together it's absolutely correct to call it a battery (specifically a battery of supercapacitors, instead of a battery of electrochemical cells). Note that I doubt that the author was actually thinking along these lines when they wrote the piece, but I would argue it could still be correct.

It would have to be more than just key based, the private key also has to be encrypted forcing the user to enter a passphrase before the key can be used. Otherwise someone with access to the system could just steal the private key file... Essentially Filezilla asking users to store passwords and then not encrypting them is the same as a program requiring an unencrypted SSH private key.

Comment Re:Or just use MythTV (Score 1) 49

B) Where is any information on this web based export? All I can find is some references to using the old TiVO Desktop software which is horrendous and painful if you do this very often and is still subject to the same CCI restrictions as MythTV would be.

F) $150/yr for guide data is ridiculous. The TCO on this product is horrible. The upfront costs may be slightly less than my MythTV setup but I've had the same HDHR Prime MythTV setup for going on 6 years now, with no signs of it stopping so that would be $850 so far just in fees, plus the original hardware purchase.

There is no doubt that the TiVO is better than the cable company DVR systems, those are really terrible. What I asked for though was someone to show something better than MythTV since the GP was basically making the argument MythTV was useless anyway. I don't think that's been done yet.

Comment Re:Or just use MythTV (Score 2) 49

This. I switched my backend off Mythbuntu some time ago (once it became feasible to install reasonably recent copies of MythTV in other ways). But on frontends I really just want something that takes little time to configure and connects to the backend, very much appliance like so I've stuck with Mythbuntu. My suspician is that there is a pretty small minority of people running separate backends and frontends though so that's a pretty small audience. It really is ideal though, my frontends do seem to crash, stop responding to IR, etc. occasionally and need reboots. It's definitely nice to have the recording work being done in a rock solid VM so it is not interrupted by reboots.
