  1. They are claiming around 35ms (altitude is only around 1100km)

  2. 5.6 is a minor release. PHP 5.0 (first major series release) came out July 2004... and 7.0 came out almost 3 years ago. I've used PHP off and on since 2.0.... If memory serves me, there were major breaking changes between 2 and 3, a few breaking changes between 3 and 4, rare few breaking changes between 4 and 5 and rare few between 5 and 7. The main exceptions I can think of are around misguided features such as magic quotes which were rightly deprecated.

    We have quite a lot of old code in production that hasn't changed much over the years... it may not be pretty, but as long as caution was taken, just works. The same is true of most any language.

    Brazilian money is pretty strong. You need just 3.5 Reals to buy one dollar. Comparing the eighth economy [fifth in 2008] in the world with Zimbabwe shows your stupidity pretty well.

    It's currently about 4 real to the dollar. Just 4 years ago, it was around 2. That may not be up to Zimbabwe's level, but that's crazy high inflation.

    I recently upgraded from the old kindle keyboard model to a voyage and love it. The page change buttons on the side are great and provide a little tactile feedback. The adaptive light is also very nice, especially if you like to read at night. I expected the battery life to be terrible in comparison to the old keyboard model because of the light... but it rarely needs charging, even under heavy use.

  11. Re:And the money flows as fast as the data. on Municipal ISP Makes 10Gbps Available To All Residents · · Score: 1

    Assuming your numbers are correct... the population of Salisbury is 33604 as of 2013 (10,276 households as of 2010), making a loss of $372/person or $1,216/household last year alone. The median household income was $32,923. Assuming every household subscribed to the $45/mo package, that brings the cost to $146/mo for a 50mbit internet connection or more than 5% of each household's gross income. This is of course, assuming that the 12.5m loss is an operating loss and the 7.6m wouldn't be added to it.

    5% of the median family's gross income for a home internet connection is crazy.

  12. The problem with HTML5 for video on Twitch Is Ditching Flash For HTML5, Just Like YouTube · · Score: 4, Informative

    For live video, there is no working standard. HLS is used by Safari on Mac, iOS, supposedly MS Edge (I haven't tested to see how well supported it is) and is very buggy in Android (to the point of being unusable). There are some data injector APIs for the latest versions of FF and Chrome where there have been attempts to implement HLS and DASH, but they are buggy at best and not suitable for production. Additionally, using HTTP based streaming standards (such as HLS) for fully live results in very long delays (up to 30 seconds) Trying to use overly small segments to reduce latency results in video breaking up unless the latency between server and client is extremely low.

    For long format on demand video, there is an enormous amount of wasted bandwidth as the MOOV atom of an MP4 is transmitted before the video is playable. For a short video, the MOOV atom is small. For an 8 hour video, the MOOV atom can be huge. This presents a problem for support of long format video for people on slower or metered connections.

    The only thing the video tag does somewhat consistently across platforms is play back h.264 baseline+aac MP4 on demand videos that are relatively short format .

    None of these problems exist with flash. Seamless switching between bit rates is also an issue (works well on fully implemented HLS clients, but generally a problem everywhere else). In the mean time, to support live the best bet is often RTSP on most android (or a commercial third party HLS library deployed in an app), HLS on iOS, some TV devices and on the few supported browsers on desktop and flash for everything else on desktop (where there are player implementations that support HLS).

    Yes, flash has a history of security problems. There are still many things that it does much better and more consistently than HTML/JS. I'd love to dump it, but there aren't any solutions that work well for live without a plugin across all platforms.

    Bombs that large don't exist outside of the US and Russia. The largest bomb ever detonated was designed as 100mt but only produced a yield of 50mt to reduce fallout.

    This bomb (Tsar Bomba) is huge, and must be delivered by a very large plane.

    Generally, missiles carry at most 1000kg payload. This bomb is about 27 times that. I don't believe there is a single bomb anywhere near that size that can be delivered in a practical manner.

    The cobalt secure server is RedHat's secure server compiled for the Cobalt RaQ/Qube systems. We have ran into quite a few problems with SSL because we want to use PHP under SSL, and haven't been able to get Cobalt to release apxs, headers, etc. We ended up just compiling apache w/ mod_ssl (and own a copy of the RSA licensed secure server that cobalt sales).

  16. Re:If it don't have a console port... on Gateway to Sell Cobalt Systems · · Score: 1

    I'm not certain about the Qube (although I think they do), but the Cobalt Raq does have a serial console port. No, it's not made to hook up a PC monitor, but they are an excellent "server appliance" and seem to save quite a bit of time with administration.

  17. Multiple Sound Cards - The Easy Way on PCI Sound Card Recommendations for Linux? · · Score: 1

    I've been very happy with the Creative/Ensoniq AudioPCI cards (es1370/1371). With the driver compiled as a module, just modprobing detects and loads the driver for every ES1371 card in your machine (up to 8, I believe... but I haven't found a motherboard with that many PCI slots yet). They're relatively cheap, and play/record relatively well. I use them along with SLab to do multitrack recording & mixing.

    The only product I know of that is similar is the netwinder, which is much more of a micro-workstation than server... and the cobalt interface gives you a really simple way of allowing the clue-impaired to manage email accounts, etc.

  19. Microwave networking on Microwave/High Frequency Private Broadcasting? · · Score: 1

    I know that certain microwave frequencies can be used by the public for this purpose. I have worked with several LAN/WAN links between 1-5mbps over several miles. I think they are in the 2ghz and 40ghz ranges, but I really don't know a whole lot about this... as is why I posted the article.

    BTW... they were PtP (point to point) links, not broadcast... i.e. dishes tuned and pointed directly at each other. Depending on your use, this could be a crucial factor.

  21. Re:Video input types... on Ask Slashdot: Multiple Webcams and FreeBSD · · Score: 1

    To do this, i'd recommend a card with a composite input (as most of them have). I apologize for the confusion... RCA is actually a connector style as you would find on the VIDEO IN on your VCR. You would use a composite signal. Most VCR's and cheap cameras will use a composite signal... and you can stretch it quite a distance... although I'm not sure the technical limitations on this.

    There really isn't much to using the PC parallel port for basic controls. Here's a decent example... all that needs to be done is buffer it and attach a relay... I'm sure there are other ways... but that is probably the easiest.

    PC Parallel Port Info

    has some basic information on the port and an example interface use...

    Let me know if I can be of further assistance... granted there are probably people around here with much more of an electronics background.

  22. Many cameras, low system load on Ask Slashdot: Multiple Webcams and FreeBSD · · Score: 2

    1. Find a good video capture card supported under Linux which also has an RCA IN. There are several cards that qualify.

    2. Build a small parallel port controller box (an easy method would give you up to 8 cameras, but with a little more electronics, you could handle quite a few more). The box should switch the RCA inputs when a data line is toggled.

    3. Get a few cheap B/W video or security cameras. You should be able to get these for $50 U.S.

    4. Write a quick script or C program to snap a picture, toggle control line, etc in a simple loop... have it place the files in a directory on your web server. Create web pages with a refresh tag, and have them load the file which the script will refresh.

    That's about it... hope this helps.
