usb keyboard, width about 15cm?
by ronwirring＠Safe-mail.net 26 May '17

26 May '17

I have searched the best I can for a seller of a small usb keyboard. Width about 15cm. Keyboard may include a touchpad. I cannot find a seller. I have asked on forums. No answers. http://usb.brando.com/prod_detail.php?prod_id=00666 Seller says, he has stopped selling the keyboard and he does not know where a keyboard of this size is being sold. Do you know if I can buy a keyboard of this size? Thank you.

modifying a 7 inch notebook cabinet to accept a pc card
by ronwirring＠Safe-mail.net 26 May '17

26 May '17

On another forum I asked about the practicability of modifying a 7 inch notebook cabinet to become pc card compatible. Lkcl rejected my suggestion. He argued, that keyboard, sound, batteri etc would require custom pcbs. Expenses worth thousand of eus. Doing it wrong and the computer could catch fire. I am not going to spend thousand of eus. I will try to modify a computer. I have no expectation, that I will be able to do it. I have come to think that the pc card is a raspberry pi. If your display is hdmi and other devices are usb, then you have a computer. On youtube I found a person who had turned notebook's touchpad into an usb touchpad. I asked him about modifying these notebook devices to usb: speakers -> use an usb soundcard mic -> use an usb soundcard camera -> notebooks camera may be an usb device. Else get an usb camera. touchpad -> many synaptic touchpads are usb compatible. I do not know what to do about the left and right buttons. keyboard -> that will be difficult. battery -> likely difficult. At least if you want to be able to charge and have the computer turned on at the same time. display -> either get a lvds to hdmi converter or get a hdmi display. I do not now if a 7 inch hdmi display requires separate power. It appears the keyboard is the biggest difficulty. On his website one person wrote about modifying a notebook keyboard to an usb keyboard. He wrote it is about getting a controller which will fit the keyboard's wiring. Then it is a matter of mapping the keys correctly. I do not know about powering the keyboard or rather the controller. I bought a 7 inch display asus eee pc 4g. If you get to use the battery cabinet, there ought to be space for the devices. Tell me what you say?

mailing list settings

as an experiment i'm setting "content filtering", particularly the option to convert text/html parts to plain text, but it also strips multipart/alternativee and a few other things. the general idea is to make it easier to interact on complex multi-reply topics by enforcing text-only. replying to text-only should, by default in most mailers, result in the familiar ">"s for every single line, as per standard netiquette guidelines. i will test this shortly. test line test line test line test line test line test linetest line test linetest line test linetest line test linetest line test linetest line test linetest line test line test line test line test line test line test line test linetest line test linetest line test linetest line test linetest line test linetest line test linetest line test line

First I list lkcl's reasons why he thinks reverse engineering is a bad track. I agree on his arguments. Next I say, why I believe it is better doing a reverse engineering. If you do not accept the principle of weighing arguments up against each other then that is your decision. I specifically wrote in an earlier post, that for me the arguments in favor of making a reverse engineering of a mali gpu are stronger than against. > >Weighing them up against the importance of getting a libre software gpu, I reach the conclusion that the reverse engineering should be done. > Before you plan a difficult crowd funding campaign and involve the FSF, please tell us your > counter arguments to Lukes reasoning on a technical and ethical level. I do not have any technical arguments about a reverse engineering. I have no insight about reverse engineering. To my knowledge it is one of the most difficult fields about computers. I asked if a reverse engineering can be done? Lkcl said yes. My political arguments align with those of libre software. Watch https://www.youtube.com/watch?v=Ag1AKIl_2GM I think it is important having libre software electronics which are able to match the performance of non libre electronics. We should have at least one libre software mali gpu we can ask people to buy. > For example to the following points I am quoting from Lukes email reply to you in > the thread about "firefly 3399 all source software disclosed?": > - "take one of the "open gpus" or parts of them and use that." > - "the sad fact of reverse-engineering: all that effort, with > *no guarantee of success*.... just to get something that's years > out-of-date." > - "well, with the same money it would be possible to make our > own libre processor, with enough extensions to be able to do 3D > graphics *without* paying anyone a cent." I have not heard about this option before lkcl wrote it. I have not heard anyone else mention this option. If lkcl's suggestion is practicable, it is another prove of the lack of coordination among libre software people. > > > There have been some remarks about the probability of a successful crowd funding.

Notice on this email list, people want to pay 5eu, if they get the software in question. > >It is safe to say more than 10 million people have gnulinux on their computer? A major part of them know about the importance of libre software and a part of them would want to act on it. > I don't know if your numbers are correct but it seems important to me to I do not know either. I do not think there are statistical numbers or questionnaires on this matter. My major arguments are, more than 10 million people likely know about libre software. If you asked them one by one, if in the same prize range, do you want to buy libre software electronics over non libre electronics, many would answer yes. Providing libre software electronics would require a very high degree of coordination. Every major gnulinux forum and organization should display the crowd funding at the same time. I have so far not seen a crowd funding about libre software electronics that would display no matter what entity on the internet people would watch. Proven is, on many areas of consumer electronics we cannot buy libre software devices. > point out that only a fraction of all GNU/Linux Users own a device with > a mali GPU.

EOMA68 Router Ethernet Speed
by Erik Auerswald 25 May '17

25 May '17

Hi, on http://rhombus-tech.net/community_ideas/router/news/, the text and picture feature Gigabit Ethernet interfaces. Just one sentence mentions 10/100 Ethernet in passing. IMHO that is misleading. AFAIU the QCA9531 provides Fast Ethernet only, *NOT* Gigabit Ethernet. Thus please change any occurrences of GBE/GbE/Gbe or similar with FE, perhaps excluding the very first sentence. While Fast Ethernet is good enough for most uses, it is not Gigabit Ethernet. Please correct the web page. Thanks, Erik -- Reality continues to ruin my life. -- Calvin

On (potentially not) 3D printing laptop case parts
by Forest Crossman 25 May '17

25 May '17

Hi, all, The recent update on Crowd Supply (regarding the difficulty in mass-producing parts with 3D printers) reminded me of some RepRap/RepStrap innovations from a few years back: - https://web.archive.org/web/20150318000301/http://justindunh am.net/making-cast-resin-3d-printer-parts/ <https://web.archive.org/web/20150318000301/http://justindunham.net/making-c…> - http://reprap.org/wiki/Clonedel - http://reprap.org/wiki/Moldmaking_Tutorial This was before cheap, mass-produced 3D printers became widely available, so many people were bootstrapping their RepRaps by purchasing 3D-printed parts from others. At some point, someone realized that it was a lot faster to 3D print a set of parts, make molds from them, and then use those molds to make additional part sets, than it was to separately print each set of parts. I'm not sure how complicated the parts of the laptop case are, but if the parts could be re-designed to be optimized for resin casting, it might cut down on the production time. Of course, I've never done any resin casting before so I don't know how feasible this would be in practice. Also, I have no idea how fast modern 3D printers can run now, so the speed advantage might not even exist any more. Anyways, I just though I'd mention this on the off chance it might help speed things along. Keep up the good work! -- Forest Crossman

-------- Original Message -------- From: Neil Jansen <njansen1(a)gmail.com> Apparently from: arm-netbook-bounces(a)lists.phcomp.co.uk To: Eco-Conscious Computing <arm-netbook(a)lists.phcomp.co.uk> Subject: Re: [Arm-netbook] mali gpu reverse engineering lkcl may ignore Date: Mon, 22 May 2017 17:28:21 -0400 If you reinterpret what I write then tell on what grounds. I think lkcl's reasons for not reverse engineering a mali are right. Weighing them up against the importance of getting a libre software gpu, I reach the conclusion that the reverse engineering should be done. There have been some remarks about the probability of a successful crowd funding. I mentioned the numbers 50000 people, each paying 5euro. Notice on this email list, people want to pay 5eu, if they get the software in question. It is safe to say more than 10 million people have gnulinux on their computer? A major part of them know about the importance of libre software and a part of them would want to act on it. I agree about the responses on the practicability of a crowd funding. I am not sure a crowd funding can be done successfully. I would like to know why? Why cannot such campaigns be coordinated centralized? We should have a known entity, which would approve libre software related crowd fundings. People would know them to not be scams. Why does an entity like the free software foundation not take on this task? I should ask them. About these fragmented crowd fundings, you yourself have to make a validation, which is difficult. When lkcl initiated his pc card crowd funding, I did not know him. I still mostly do not. On trisquel's forum people referenced thinkpenguin. Thinkpenguin endorsed lkcl. That is why I supported lkcl. Is the free software foundation not involved because they fear scandals or not have enough resources? The matter about libre software consumer electronics, I consider highly important. There have been remarks about the retaliation towards people who want to do reverse engineering. How to deal with it. One option would be to let one entity collect the funding, manage public relations and another hidden team do the reverse engineering. Everything still legal on taxes. Legalities seems to be an important issue. Are these legal concerns an american matter? I do not know everything which may happen but if the public part of the crowd funding is located in eu, I think a campaign should be fine.
