Noux dev environment
by Joel Desermeau 06 Apr '19

06 Apr '19

Hello again my friends :) I'm just a junior sysadmin, but I want to learn how to program in C and C++. Could a noux environment be created with compilers and debugging programs like gdb and valgrind? Maybe one day I'll be good enough to be a Genode developer :) I can dream. Joel Desermeau

My personal wishlist
by Joel Desermeau 02 Apr '19

02 Apr '19

Stickynotes are cute and would be easy to implement, but here is my real Genode wishlist: Email client - I would be happy with anything IRC client - I love communicating with IRC chat, and the folks at #genode are very helpful :) RSS Reader - I have my most important news sent to me via RSS, and it seems most Genodians like RSS as well Native Firefox - this is but a dream Office Suite - I hear LibreOffice is being ported to Genode?? Cool stuff indeed VPN - Wireguard/OpenVPN GUI audio player With all of this, I would be able to switch to Genode without needing to virtualize anything. I would be as happy as a clam

iMX6 sd_card file systems > 2GB
by Pirmin Duss 02 Apr '19

02 Apr '19

Hello Genodeans I have created a run script that creates a file system a SD-Card (4GB) connected to my iMX6q. Whenever I try to create a file system that is larger than 2048MB, mkfs.ext2 fails with "Bad file descriptor while zeroing block 953328 at end of filesystem". This lets me think, that probably there is a overflow in a signed 32-Bit integer somewhere. I have tried to understand how the sd_card_drv operates. If I'm understanding it right, the read_dma()/write_dma() functions pass the block_number (64-Bit value) to the constructor of Write_multiple_block, which in turn stores it in its arg member (32-Bit register). But this, truncation of the block number, would not explain to me why the error occurs after 2GB, as the data on the sd_card is accessed in blocks of 4096 bytes. Can anybody help me with some clues, where to investigate further? Best regards, Pirmin

Yes, I'd better even merge the content of both articles, and create a redirect from one name to another. The existing article also contain some additional information, some of which is outdated. As people noted, the old russian wikipedia article existed before any other national articles, and it contains some original content, whereas other national articles are mostly translations of the english one. So, russian article misses some useful info that the official one contained, but it contains some extra info. > The old article seems to be updated, though, because it shows the > latest Genode release. Yes, there were some edits in this month. So, it is a bit updated, but some info, like about L4Linux port, which is discontinued, is a bit outdated. > Maybe we could get in touch with the author who did these latest changes > (in case it was not you). If this is not feasible, we could mark the > old article as outdated and link to the new one at the top. Yes, I also think so. I need to contact the original article authors and discuss it with them. (I know one of the authors, it is my friend Oxyd. But he had disappeared for some time, so I need to have the occassion to meet him again to discuss it). For now, I created the draft for my translation here: https://ru.wikipedia.org/wiki/%D0%A3%D1%87%D0%B0%D1%81%D1%82%D0%BD%D0%B8%D0… Most probably, we'll need to join the content of both articles into the "Genode" article, and create a redirect from the "Genode_OS_Framework" page (or vice versa). Greetings, Sebastian

QTimer clock source in Genode
by Steven Harp 01 Apr '19

01 Apr '19

I tripped across a situation where one of my Qt5 applications that used a periodic QTimer stops receiving timeout signals after 1 hour 10 minutes of normal operation. (This is in Genode 18.08, x86_32 and x86_64, nova and seL4.) The same application keeps on ticking (for many hours at least) when compiled and run under Linux. A Qt Forum participant speculates "a 2^32 wraparound? Because 4294967296 (2^32) microseconds is 4295 seconds." This is just about the observed time. The Qt5 documentation suggests that some Qt timers on some platforms can have this problem--it depends on the underlying clock source. Can anyone comment on the relevant clock source for QTimer in the Genode port? For reference, a native Genode Timer connection does not exhibit this problem, so using it in this application was a viable workaround. // Steve

Using binaries with debugging symbols instead of stripped binaries
by Parfait Tokponnon 01 Apr '19

01 Apr '19

Hello, I am using Genode with Nova kernel and I would like to build seoul-net scenario with the un-stripped binaries (the kernel also included) for debugging purpose. Currently, the build script uses stripped binaries by default. I found in old mailing exchanges that this may be achieved by commenting 'copy_and_strip_genode_binaries_to_run_dir' in tool/run/run but this line is not available anymore in the current version. How can I instruct the build script to use the debugging binaries? -- Parfait T.

What feature I would like most of all: stickynotes
by Joel Desermeau 31 Mar '19

Yes, that would be it exactly! It could be a heavily stripped down version of the qt5 editor that we have already. It would be very lightweight with a cute yellow background > Hi Joel, > > On 29.03.2019 01:44, Joel Desermeau via users wrote: >> > > A stickynote application for nitpicker would be beautiful > > would this be like a small text editor window which autoloads a specific > file when started? > > Christian

Re: New french Wikipedia article about Genode

Hi Valery, It's really cool to read that you want to work at the russian Wikipedia article! Please let me add some personal thoughts about this: I would refrain from writing a new article or substantially changing the old one without first getting in touch with the original authors and having a corporate plan. Writing a new article single-handedly would either render the old one outdated, eventually causing its deletion, or mabe even the new article ends up in not being accepted by the Wikipedia folks because of the redundancy. During the period in time were both articles would be online, interested readers may get confused about which source to rely on and, IMO, it would also be a statement of inpoliteness against the original authors. After all, the russian article was the first one about Genode on Wikipedia. Is there an urge to create a complete new russion article? This question is ment serious because I cannot read cyrillic at all and therefore have no idea what the russian article currently says ^^ Please don't get me wrong here - I think it's great if the russian article gets enriched with information like the "critiques" chapter of the english version but I don't think that the english and the russian article must necessarily become the same (with the same name). Maybe I'm wrong with these thoughts. What do you think? Cheers, Martin

Translators for the Wikipedia article
by Martin Stein 29 Mar '19

29 Mar '19

Hello Genodians! I'm very interested in expanding the set of available languages for the Wikipedia article about Genode. Currently, the article is available in Russian [1], English [2], German [3], and Spanish [4]. The russian article is a version on its own while all the other articles are translations of the english version. Unfortunately, I don't speak as many languages as I wish to see in the above list but have had a fun time when working on the german and spanish articles. This is why I'd kindly invite everyone who'd like to contribute a little bit to the Genode project on a voluntary basis and whose native (or well-known second) language is still missing in the list. I'd like to propose the following if you're thinking about a contribution: * If you like, we could work together on it remotely. As long as it is at least a latin-alphabet language and you're planning to translate the english version, I feel capable to carry the transition of your plain text translation to a Wikipedia article with an infobox, images, references, and crosslinks. * Maybe you're also participating in the Hack'n'Hike gathering in May [5]? Then, we could meet there and collaborate. Let me know about it ;) * Of course, you can even do it all on your own. In this case, don't hesitate to mail me any questions that are coming up! I'm looking forward to hear from you! Cheers, Martin [1] https://ru.wikipedia.org/wiki/Genode_OS_Framework [2] https://en.wikipedia.org/wiki/Genode [3] https://de.wikipedia.org/wiki/Genode [4] https://es.wikipedia.org/wiki/Genode [5] https://github.com/genodelabs/genode/issues/2841
