Re: Qt and alsa mixer
Hello, I don't think so. Some years ago, I wrote qalsamixer (GPL) for qtopia. You can try that. It should also work on the desktop. I have forgotten if I needed to modify it for desktop use. Your mileage may vary if alsa API has changed since then. http://github.com/radekp/qtmoko-apps/tree/master/qalsamixer On 13/07/10 3:46 AM, ext Nicola Mfb wrote: Hi!

Well, I suppose ignorance can be forgiven since an announcement hasn't actually been made yet, but I'd recommend reading up a bit before you jump to the melodrama.[1][2][3][4] The rumors are fascinating. In the meantime, I am nearly ready to start shipping my software but my potential customers have nothing on which to run it, unless they happen to own an N8x0 already. Nokia opened their platform to encourage developers to contribute their expertise, but their capriciousness and opacity about their hardware roadmap are tolerable only to hobbyists or companies porting software from another platform as a sideline. If I postpone delivery until after the rumored next-generation platform appears, It's not _just_ a rumor. There is something else coming up: Fremantle. There is something else even more exciting after that. what assurance do I have that Nokia will not balk again? Balk at what? What assurance do I have that Nokia will not price me out of the market with an upgrade burdened with features I don't need? I am confused here, how would Nokia price you out of the market? As far as I know Nokia isn't charging for SDK and application development. Maybe there are features in Fremantle that many more would like, giving you more opportunities and a larger market than the current device can offer? If you see only melodrama in these concerns, then perhaps you have never tried to run a business in the face of such uncertainty.

Please say I am :-) You're only missing that sometimes even for proprietary software, no cost vs reasonable cost matters. Sometimes the GUI doesn't matter much, and the license change means developers can consider Qt more easily than before. (That's probably less the case for Maemo, but generally it seems likely to be so.) A more interesting (but likely speculative) question is why Nokia made the change. two words: Qt Everywhere My guess is that internally they regard Qt commercial licensing as a distraction from their main business, and (though it may be at some level irrational) they prefer to exchange the income (and distraction) for the positive publicity. We are still selling Qt as a multi licensed software, we still sell commercial licenses to those companies and people that want to keep their code closed. At the same time, we are offering support as a separate offering, so Nokia can now also make money from selling GPL, LGPL users support. As well, it removes restrictions for being able to use community contributions.

Nokia reported second quarter earnings today, which saw its net income fall 61 percent to 1.1 billion euros ($1.74 billion), from 2.83 billion euros ($4.49 billion), compared to a year ago despite its market share reaches 40% from 38%. http://mobchina.blogspot.com/2008/07/nokias-profits-drop-by-61.html So Nokia increased it market share and is still loosing sales. couldn't have anything to do with recession at all or high fuel prices, either hey? and Maemo, Maemo community was really a great chance for Nokia to make something special. They did. Besides, Nokia and Maemo doesn't make the community. The community makes itself. Today chances are lost. It's too late. oh. such doom and gloom... Just read Bloomberg and market analysis and stock reports. Chances for sucess and to be No.1 with Maemo success has gone forever to Samsung, Apple and emerging Google cell phones. really funny. I thought the n770, n800 and n810 has no gsm. If you know differently, please point me to the correct dev node and I will whack Qtopia Phone on there so you can use it as a gsm phone (oh wait. Qtopia Phone already runs on n810, silly me, what was I thinking. All thats needed is a phonevendor plugin). so no, it isn't competing with apple and 'emerging' android phones. as well, any android phone is just vaporware. Do you smell that? They let the blue smoke out of their reference boards... We should play fair. Maemo community was a great chance for a great victory by Nokia. Unsupported, with no leadership, no challenges set ended in frustration and half-finished products like low quality gps navigation, no-cell-phone Maemo. It was never meant as a mobile phone, otherwise there would be a gms chip on it. Besides, anyone can write a high quality gps navigation application if they want. Why leave it up to Nokia? The product is open enough to make any application possible. and now with qt4-maemo, it has never been easier. At the same time Samsung, Apple, Google made very fast progress with emerging technologies, multitouch products, high-quality integrated navigation. good for them. They are mobile phones... I can't blame you for a defeat, but frankly speaking, you showed no interest to make Maemo developers the Champions - world-leaders in emerging technologies and products, giving handicap to Apple and Samsung to make much faster progress. Perhaps you haven't heard about maemo-qt? Try writing an app for your iPhone that you can simply recompile to run on linux, mac and windows... Lost chance by Nokia is not my personal opinion. yes. it is. Lost chance is market analysis published by Bloomberg. I think growing in market share from 38% to 40% is doing well. But this is a differing market to what the tablets are competing in, so your point is moot. just what Bloomberg says: [snip some mumbojumbo personal opinions] The only chance for success is to have comm unity of developers really integrated with main development strategies again, see maemo-qt4. it is the future I think... and my suggestion to set up Think-Tank made some months ago was the right direction. ok. so where is your thinktank and what documents have they produced?

All the filesystem is stored in the flash memory, and the MMC is mounted in /media/mmc1. Even, you can make swapping with a file in the MMC, as appeared some days ago in Planet Maemo. I am wondering if swapping and every day writing in the internal flash could damage these memories. Some people told me that flash memories should not be used for frequent disks writing (like swapping or every day usage of a computer). Is this relevant? I mean, could I damage the flash memory if I use the device very often and I make swap on the MMC or internal flash? Regards, Israel Herraiz Older NOR flash has a 100,000 write limitation (complete write), NAND flash has about one million write cycles. All flash memory these days is NAND.
