Re: SD/MMC cards, a year later
I have read that article before, and counterfeiting isn't the only explanation. Vendors are free to do whatever they want in terms of modifying a product with the same labeling. - Ed On Aug 20, 2010, at 5:34 AM, Tiago Marques wrote: Have a look at the previous link I sent then.

Re: SD/MMC cards, a year later
One frustration has been the rate of change in the SD industry. The dominant model from a vendor in a particular size and speed may only be in production for three or four months before being superseded. Vendors are reluctant to properly inform Quanta of changes which might require retesting. The result is that SD card certification is an ongoing process. How many do I have to buy before a distributor or manufacturer will cooperate? Or how much extra does it cost to get them to cooperate? Is that whole industry segment so focused on low-cost that nobody knows how to keep track of what they manufacturer/deliver? What do cell phone manufacturers do? -- These are my opinions, not necessarily my employer's. I hate spam. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

How many do I have to buy before a distributor or manufacturer will cooperate? Or how much extra does it cost to get them to cooperate? It appears to be a matter of cost more than volume, although it can be difficult to differentiate the two. Is that whole industry segment so focused on low-cost that nobody knows how to keep track of what they manufacturer/deliver? Some manufacturers track this relatively well (although it can be hard to get them to communicate this information). Others (whom we don't deal with at all) seem to have little to no control. What do cell phone manufacturers do? A number of them are paying a premium for eMMC chip from a single manufacturer to get around this. Others just accept that failures are going to happen. Note that almost all the SD cards I've tested would work fine for average use. In my testing, I'm expecting cards to survive a usage that is equivalent to filling half the card with new data (2 GB) every day for five years. Both Apple and Microsoft are using raw NAND flash chips in their products as a way of maintaining more control. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: [Server-devel] Schoolserver development in Uruguay
Hi, I must confess that I am not current on this list. However, I'll toss in two cents. First, I would like to see a build process that starts with a generic (Fedora) LAMP system. There should then be a build script that creates a schoolserver on this system. The current process (as used in Nepal) starts with the 0.6 image which locks it to Fedora 9. A deployment could then build their own script to add (or remove) services. Second, The idea of the DataManager activity is to replace the current backup scheme by one controlled by the students. DataManager shows a Journal-like listing of all the journal items on the server and on his or her XO. If the item is on both, it is shown in Blue. If it is only on the server, it is shown in Cyan. The student can delete a Blue item (leaving it only on the server) or can click on a Cyan item causing it to be downloaded to the XO. A 'fuel guage' shows how much of the Nand is free as a guide on whether to delete some local items. All newly created items are copied to the schoolserver - provided they have an associated data file; otherwise they are deleted. This policy is based on my reading of the code that journal items which do not have a file are not 'resumed' (in 0.82). The 0.82 scheme gives the student no way to avoid filling his Nand or controlling what gets saved or discarded (e.g if he/she deletes a Journal item on the XO, it will be deleted on the backup as well). One additional advantage is that the DataManager supports a 'commons' folder on the schoolserver which acts as a Journal store but whose items are available to all XOs. Currently, the commons folder contains a copy of the Sugar activities. This way students have access to all of them and can decide which they want to have local. If one is removed, it can be downloaded again. If the local store is lost (e.g. by the student changing XOs resulting from a hardware failure), all of the journal items are still accessible via the DataManager (given suitable update of the schoolserver to reflect the new serial-number).
