I'm currently in Lisbon, Portugal at the Real-Time Conference 2010. I won't write about it just now, since it just started and I'm tired.
But here's something that just surprised me. If only all laptop batteries would improve this way: design capacity: 69000 mWh remaining capacity: 72880 mWh
The KDE-Edu team is very productive in Randa. On the second day we started with a Logo session. Our eyes keep seeing logos in the everyday life and we have been wanting a logo for years. At the meeting, Alexandre from Brazil, a professional designer, watched us the whole first day when we talked about who we are, what are our targets and about our programs. He then started to work on a logo concept: he defined a few verbs about KDE-Edu and came up with the conclusion that KDE-Edu makes people's knowledge grow. So the main idea behind the concept is "growing knowledge". The logo is still in its infancy so please don't comment like "I don't like it" or whatever without being productive. We as a group, after the logo was presented, did not do a "like/hate" unproductive waste of time session. We agreed that the concept idea was good. One thing Alex also said is that if a logo looks good as a stamp, in black and white, it'll look good anywhere. It'll come into ...read more...

KMyMoney is now in kdereview. It has to go through a 2-week review before being approved to move to extragear. Given our development experience (we are by no means a new kid on the block), I expect it to be fine. As part of the process, I had to prepare a small summary about the current MyMoney development situation, which I think is worth sharing here:
So, first coding day. in the morning we had an awesome breakfast then fastly we went upstairs, to the 4th floor and opened our laptopput it in the back of a red VW microbus, took shovels and rakes and implements of destruction and headed on toward the city dump. up there was the Multiemdia people with the KMix, Kdelive, Amarok, VLC, and others talking about multimedia, and also Apol, Me, Alexandre, Annma, Sput and such talking about edu stuff.
We had to drink a lot of bottled water, since programming is something that really tires a persons muscle, it had a funny taste and was a bit yellowish. I had to get proper water in the tap.
24 * 9 bottles of beer on the wall.
The big brother watches us from his tower of wisdom.
hi! just a quick note that a new method of reporting bugs in KDE's bugzilla has been pushed to the live server after setting on the test server for quite a while.
Today I released the initial version of Smaragd, a themable window decoration engine that allows you to use Compiz/Beryl Emerald themes together with the KDE window manager KWin.
This version is not yet ready for production use (there are no shadows and theme installation has to be done manually), but you can already start choosing your favorite theme out of over 1500 available Emerald themes.
There have been some great additions and refinements in the last few weeks and picking the best is going to be a difficult task. But we don’t mind if you make it still harder
(This post was published on Friday, but I put in a wrong tag and I didn't get aggregated, so, republished)Although I've been hacking on my GSoC project for quite a while, doing little experiments and getting my mind around various factors involved, this week was my first official coding period, since that was what I had in my timeline.The first piece to implement is the kioslave to browse UPnP
It's been a while since the last Top 5 has been released. My apologies, but I attended the VMware Technical Summit, was on a holiday for a week in Italy and two close relatives passed away. Anyway it is Sunday again and tomorrow a fresh new weeks start... no apologies any more. We will continue with the Top 5 as of this week again. It took me a while to go through the immense list of articles, but I guess the following 5 stood out.
Bob Plankers - What are P-states and how do I use them in vSphere? VMware vSphere 4 added the ability to take advantage of Intel SpeedStep and AMD PowerNow! CPU power management features. These features are commonly known as “Dynamic Voltage and Frequency Scaling” or DVFS, and let an OS cooperate with the CPU to reduce power consumption by reducing the frequency of the CPU and the voltage at which it ...read more...
I've been looking for a local store which offers a colour sprectromitor and chanced upon the spyder3. I have to say that it is a total let-down. It doesn't work on Linux to begin with. I feared this going in but the gracious return policy at the store allows me to buy things and simply return them within two weeks without any reason - my standard answer is "It doesn't work with linux". They smile and give me my money back - great store, they get a large part of my earnings :-)
In the case of the spyder3, it didn't even work with windows, really. No more whites, everything is blue, the colour profile it creates is horrible. I tried it with daylight, incandescent, etc and to be honest I can do much better with my eye. Definitely returning it when I get back from my trip to London and the Libre Graphics Meeting. Crap in a box for 99? if you ask me.
If you want to try out Qt 4.7 and the interesting new world of Qt Quick ("from now on /the/ way to make GUIs"), Kubuntu 10.04 users can try it from the experimental PPA. The Qt Creator packages there have Qt Quick designer integration.
В начале апреля исполнилось 2 года с момента принятия OOXML в качестве международного стандарта. Первая попытка принятия в сентября 2007 года успехом не увенчалась, однако он всё-таки был принят полгода спустя после серьезного пересмотра и разделения стандарта на 2 редакции.
Предложения с изменениями составили около 1500 страниц. Как сообщает независимый технический консультант Колин Джексон, участвовавший в заседаниях комитета в составе делегации от Новой Зеландии, их принятие в конечном счёте происходило скопом в виду очень большого числа. Вместе с тем он не отрицает, что были приложены немалые усилия многих специалистов из разных стран по улучшению стандарта.
Редакция, не прошедшая ратификацию в сентябре 2007 года, с несущественными измененьями и большим количеством выявленных проблемных моментов была предложена в качестве отдельной версии стандарта, названной Transitional OOXML, в то время как доработанная и исправленная версия получила название Strict OOXML. Перед Transitional-версией были поставлены вполне благородные цели --- "необходимо наличие переходного периода, в течение которого существующие документы в бинарном формате могли бы использовать устаревшие возможности для сохранения точности их воспроизведения".
По словам Джексона, всем участвовавшим в работе комитета было понятно, что программное обеспечение, а тогда был свежий MS Office ...read more...
Mike Arthur, the man, the legend, the red haired Scott joins KDEMU.
What is KDEMU you ask? It’s an *all* KDE show that will cover a wide range of KDE topics, releases, interviews with developers, etc.
If you are a KDE contributor and want to talk about your work in KDE or just want to co-host a show or two, feel free to email me or use the contact form in my website.
Since api.kde.org has been down a lot lately, I generated some Qt Assistant-compatible documentation from kdelibs, and put it up on my server, and also linked to it from the topic in the #kde-devel IRC channel. But since not everyone visits IRC, I thought I’d mention it here too. So, fetch kde45.qch and save it somewhere save, launch Qt Assistant, go to Edit
I arrived on Thursday afternoon in Randa, in a beautiful scenery with big mountains and white summits. The weather is quite sunny (not that we have been out a lot today ;-) and the house is very nice. We started working today with a together session to get to know who each other is and how we can share knowledge. Then we split and in the KDE-Edu side, Frederik started with suggesting topics we could work on, community-related for KDE-Edu. You can follow the proceedings here: http://community.kde.org/Multimedia/Sprint2010/Schedule#Friday.2C_May_21. We defined the schedule and had quite a full and productive day. We're noting everything down and we try to keep focused on the topic. We're focused in defining what is the KDE-Edu project more than hacking widly although we branched kdeedu for 4.5 and opened trunk for 4.6 as an exceptional measure. It's very nice to be two groups (plus some satellites) as we feel more part of KDE overall and we benefit from other people energy and input. Needless to say that Mario has been and is ...read more...
На конференции разработчиков Google I/O, проходившей 19 и 20 мая в Сан-Франциско, объявлено о доступности высококачественных шрифтов с открытым исходным кодом для использования в Интернет.
Компания разрабатывает ряд шрифтов доступных через сервисы Font Directory и Font API. "Интернет отстал от печатных СМИ в качестве типографии и мы надеемся, что благодаря поддержке браузерами наших шрифтов улучшится визуальная составляющая и разнообразие Интернет" - заявили в Google.
Пока доступны 18 шрифтов (два из которых первоначально были предназначены для Android), над которыми уже можно начать работать. Код позволяет использовать шрифты во всех браузерах. Поддерживаются CSS3 и HTML5 стили (тени, вращение и т.п.).
Подробная информацию о Google Font API и Google Font Directory - в блоге Google Code.
In the first part of this series on Exchange 2010 on vSphere the focus was scale-up performance of a single Mailbox Server VM. The results showed performance was great across all points tested, ranging up to 8000 users. This article will take a look at disk I/O which is an important aspect of Exchange performance.
Enhancements made to Exchange 2010 have resulted in a reduction in disk I/Os per second (IOPS) in comparison to previous versions. This reduction is reported by Microsoft to be as big as 70% in some cases. Exchange 2010 makes more efficient use of memory as a cache which results in fewer reads and writes to disk than before. However sufficient memory is still very important for optimal performance. Exchange 2010 also uses ...read more...
Вышел релиз iptables 1.4.8 — интерфейса к Linux-фаерволу netfilter.
Наиболее интересным новшеством данного релиза является поддержка conntrack zones — механизма, позволяющего корректно отслеживать соединения в случае подключения хоста к двум или более сетям с одинаковыми адресными пространствами через разные сетевые интерфейсы. Такая ситуация является достаточно редкой, но тем не менее довольно неприятной, особенно в том случае, если вы не можете ничего изменить.
Стандартный Linux-фаервол netfilter использует для отслеживания соединений интегрированную в ядро подсистему conntrack. Полученная информация затем может использоваться при фильтрации и преобразовании пакетов. Например, именно на базе этой информации работают критерии conntrack (проверка состояния соединения, его устаревшая версия известна как state), connlimit (ограничение количества одновременных соединений с одного адреса или подсети), connbytes (ограничение соединений по количеству пакетов или байт, переданных в одном или в обоих направлениях), connmark (работает с маркировкой ctmark, общей для всех пакетов в соединении). Также информация conntrack автоматически используется всеми операциями преобразования адресов и портов (SNAT, MASQUERADE, DNAT, REDIRECT, SAME, NETMAP).
Эта информация хранится в специальной таблице (просмотреть ее можно, например, выполнив cat /proc/net/nf_conntrack). Каждое соединение описывается так называемым кортежем (tuple) — набором значений, в который входят адреса ...read more...
After a long development cycle focused almost exclusively on KMid, it's time to give some love to other projects. I've been working lately on KMetronome, a MIDI metronome for KDE and ALSA. It is the oldest project of my little family.
The only issue in KMetronome's tracker is this one year old request, which has suggested the title of this post. The "Weird Metronome" is a popular simple MIDI metronome for Windows, which is the origin of "Open Metronome".
The major advantage of Weird / Open Metronome is the definition of rhythm patterns. The drawback is that it only works on Windows. It may be a good idea to make a Linux port. His definition of patterns is very simple and elegant, if somewhat limited. It has two branches: one producing MIDI events, and the other producing digital audio.
Although I can't rule out porting Open Metronome to Linux in the future, I've decided to ...read more...
Буквально на днях, во время проведения конференции Google I/O, стараниями компаний Collabora и Entropy Wave (одни из ведущих в области мультимедиа и открытых исходных кодов) в мультимедийный фреймфорк GStreamer была добавлена поддержка недавно представленного Google кодека для потокового видео VP8.
Collabora Multimedia и Entropy Wave работали совместно с разработчиками из Google для реализации поддержки проекта WebM (распространение видео в сети Интернет в формате VP8) средствами GStreamer. Это позволит разработчикам буквально с первого дня предоставить поддержку WebM в своих приложениях и устройствах на базе GStreamer. Реализация VP8 в GStreamer включает в себя как генерацию совместимых с WebM файлов, так и воспроизведение таких файлов из других источников.
Как часть реализации поддержки WebM было создано официальное руководство по встраиванию кодека VP8 в контейнер Ogg, созданный Xiph.org, что даёт возможность потокового вещания VP8 по протоколу http. Также это означает, что большое количество приложений на базе GStreamer (видеопроигрыватели, веб-браузеры, видеоредакторы и т.д.) автоматически получают поддержку WebM.
Кристиан Шаллер (Christian Schaller), руководитель Collabora Multimedia:
У WebM есть потенциал стать основополагающим проектом в плане распространения видео в Интернет, и мы рады участвовать в этом наравне с Entropy Wave и ...read more...
