IBM missed the small OS
Microsoft missed search
Funny how that works. You would think they could set up a corporate process to analyze and evaluate alternative approaches, and then meet with the HR department to classify the requirements and determine the appropriate.....
Yes the risk that data stored is wrong (somebody uses phony plates, clerical error, unauthorized access...) seems like a big risk to everybody. Many times have I read stories of police going to the wrong address with things turning out badly. This just seems like another thing to go wrong.
I see a few people walking around with bluetooth headsets. Maybe "invisible" hearing aids are expensive, but another option would be to use(hack) these cellphone headsets, or even use an iphone (there noise cancelling sw built in). People are used to seeing them - just have to convince your mom.
While I would not expect that the drive cables should affect the audio in any way, I have been in hardware development long enough that when a software person makes some strange claim like"the circuit changed and I didn't do anything" that often there is something behind it. In short, these things are complex. Not that the cable should not make any difference. Maybe in his motherboard, the terminations are not good and the EMI in the board is affecting the audio. This cable may be a better match. I am not saying this is the case, but do not write off these things just because they do not make sense. That said, the writer should also try to replicate on several platforms etc etc
I would imagine this kind of software would be too complex and specialized to be effectively reviewed at large. And who would still be responsible if something was wrong? There would be discussions to no end on how to do things.
However, some kind of vault (government or 3rd party) to store the source would be good just to prevent intentional or accidental loss of the information should long term statistics show something is not right.
If the software is open source, then the whole design may have to be open.
I think a classification and storage system would be more useful than software, but maybe you are talking about a very large number of components. If you want to roll you own, I started a very basic asset tracker using based on PHP. It's maybe slightly more useful than a spreadsheet. You can find it at http://tamb.sf.net/
The article also mentions satellites. There could be burst downloads at that quoted rate, but each terminal (which will not be 60 million) does not get continuous full bandwidth.
Well it's not clear from the article if it's 224Mbps for all 60 million users. Also, the premises could have 224Mbps locally, but the end to end a fraction of that.
I wonder where is the disconnect?
Look at the huge amount of good open source software being made available every day. Contributed by many people looking for work I am sure.
One possibility I have not seen mentioned is the self-serving of managers: "project's behind schedule because can't find good help" covers up other possibilities doesn't it? So executives say, we need more people. The worker bees struggle with overwork conditions.
And I have seen this happen on the IDE as well. In my case, the fan for the bridge chip had failed causing a bit error on disk writes every few hundred megabytes. This went on for I do not know how many months before I actually did a file copy and CMP to find the errors. Ethernet and other ports were fine.
In the corporate world, from what I have seen, many patents are just applied for on behalf of someone who is looking for the purposes of self-promotion: sometimes at the individual level, or a group level. I am not making any comments on the patent system here, just that it does not surprise me that many patents do not make sense economically.
Looking at the errata (314079-12), the thermal interrupt is an old issue and not likely the cause of recent events. But the sequence of events looked like some kind of "AMT" behaviour: June 19 BIOS update released; cooling fan speed increased for no reason for a few days; Microsoft 'reliability patch' June22. Most likely it is coincidence.
I am starting to wonder about this as well:
Last week the fan on my Toshiba P100 (T5500 Core 2 Duo)notebook starting running continously just after I connected to the internet. Since I bought the machine, the CPU fan was audible only occasionally. Of course I checked the Toshiba website, and a new BIOS was made available just the previous day. I loaded it and the fan problem was fixed for a couple of days, appeared again for a few days, then went away. The notebook connects to the internet only every few days. Possibly there is a poor connection somewhere, but it quite coincidental that all this happens just before the news of the Microsoft patch on June 22.
There is some loss of quality, but one idea is to merge two or more files created from analog to create a better version. I have tried this be recording from a CD two times, then writing a program to align the waveforms as much as possible. The comparison part worked: I could see that either the sound card crystal or the CD crystal has drifted and the error between the waveform increases as time goes on as well as the amplifier noises. The next step is to continuously match the waveforms to factor out variations in the various sampling rates.
There are a lot of different aspects to testing nand flash performance. The burst speed of a 25MHz 4-bit bus (used in original SD) would be about 12.5Mbytes/sec. But data is not written immediately to flash, but stored in a buffer. An often quoted read/write speed of 9Mbyte/sec likely involves writes to consecutively addressed blocks and the SD memory block management system has a ready supply of erased blocks. Put a filesystem on top of the NAND memory block management system, and things get more complex. Fragmentation is going to be a problem here eventually as well. Did this test do any long term testing? Another factor (for PC testing) is the SD interface. Is this over USB or and SD slot such as those found in a laptop. The peak rate may be 60Mbyte/sec, but add protocol overhead, and again, random access times can be heavily affected.
I went through this a little while ago and wrote a test program which measures peak USB flash memory performance 'under' the filesystem to as to try to attain the quoted peak speeds. I have write and read results for plain blue Sandisk (5 and 8 MByte/sec) and Lexar (5 and 4 MByte/sec) at http://s3u.sf.net/
