Here is a curated list of active, responsive and valid BitTorrent trackers. Add them to the list of trackers of your torrents to increase your chance of finding peers and improve download speed.
There was a time that Apple macOS was the best platform to handle multimedia (audio, image, video). This might be still true in the GUI space. But Linux presents a much wider range of possibilities when you go to the command line.
I’ve searched for a long time and finally found a US regular bank that will let me open a free checking account. It is BBVA Compass bank. All these services are free: ATM withdraw and deposit (BBVA’s and AllPoint ATMs), full featured Internet banking, full featured mobile banking, Visa debit card, Apple Pay and more. The non-free services are […]
WordPress is packaged for Fedora and can be installed as a regular RPM (with DNF/YUM). The benefits of this method are that you don’t need to mess around with configuration files, filesystem permissions and since everything is pre-packaged to work together, additional configurations are minimal. At the end of this 3 minutes tutorial, you’ll get a […]
On December 3 Apple has open sourced the Swift programming language on Swift.org. The language was first released (not Open Source yet) about the same time as iOS 8 and was created by Apple to make Mac and iOS app development an easier task. Swift is welcome as one more Open Source language and project but is […]
I don’t know about you senior bloggers but I’m starting to hate the way the WordPress community has evolved and what it became. From a warm and advanced blogging software and ecosystem it is now an aberration for poor site makers.
Before iOS 8, the Polar H7 heart sensor with bluetooth needed special apps to pair. Now it pairs natively on the Settings app and starts sending heart rate to the new Health app on iOS 8, which will keep recording the data and building a graph like this:
At the Fedora 20 release party another guy stepped up and presented+demonstrated OpenShift, which was the most interesting new feature from Red Hat for me. First of all I had to switch my mindset about cloud from IaaS (infrastructure as a service, where the granularity are virtual machines) to PaaS. I heard the PaaS buzzword before […]
Few weeks ago I attended the Fedora 20 release party at São Paulo Red Hat offices. It was nice to hang together with other Fedora enthusiasts, get a refresh about newest Fedora features and also share my experiences as (I considere myself) a power user.
Since my Fedora Post-installation Configurations article, some things have changed in Fedora 20. For example, for security and economy reasons, Sendmail does not get installed anymore by default. Here are the steps to make your Linux home computer be able to send system e-mails as alerts or from things that run on cron. All commands […]
For some reason nobody published a simple guide like this. Maybe nobody tryied this way. I just tryied and it works with OS X Mountain Lion on a Mid 2012 MacBook Air. If you have a Mac computer or laptop and want to install OS X, and all that you have is the operating system […]
I maintain a large amount of browseable files at http://amp.alkalay.net/media/Musica/ that can be accessible also by SFTP on sftp://amp.alkalay.net:/home/pubsandbox/. You can access thse files with any SFTP (Secure Shell FTP) client on sftp://everestk2:email@example.com:/home/pubsandbox/. There is a visual way to download files from there using FileZilla. Just follow the steps.
Either if you are doing forensics or just want better reports about your call patterns, the iPhone Call History database can be very handfull. If you have a jailbroken iPhone, you can access the database file directly. If you are not, you can still access it offline simply copying the file from an unencrypted iTunes backup […]
I spent a few days to figure out how to make a simple conversion of a DBF file into a plain text file as comma separated values (CSV) or tab separated values (TSV) in a batch/command line way. I was almost setting up an OpenOffice.org server because it seamed to be the only packaged solution to […]
Today I spent several hours testing the almost amazing Samsung LED TV on a local store. More specifically the UN40B7000 model. The image quality is great and all but I was more interested in the digital multimedia features included in these new models,
Forget expensive and proprietary MS Access. Forget about applications built on top of complex muiltitab spreadsheets. Drupal with Content Construction Kit, Views and Faceted Search are the right and way better solution for you. Forget about building Flash-only web sites. Drupal and its modules is a better and semantically correct way for your Web 2.0 […]
You can say whatever you want, I’ll keep saying that Ambient Music (the style of music you can listen in albuns such as Buddha-Bar, Café Del Mar etc) is merely a fusion between New Age and João Gilberto‘s Bossa Nova.
This is a set of personal notes and a tutorial for everyone about how to correctly organize and tag MP3 files using the id3 command line tool. General way to tag MP3 files: id3 -M -2 [-v] [-t title] [-a artist] [-l album] [-n tracknr] [-y year] [-g genre] [-c comment] file.mp3 Recursively tag with […]
Since we got a 52″ Samsung LCD TV almost a year ago as a gift from relatives, I knew it was time to attach to it a dedicated computer and have a full digital media experience in the living room. I’ll tell you here my experiences building and running this thing that makes all my […]
It took some time to have my honeypot invaded again in a useful way. They were attacking constantly but were using it only to connect to IRC rooms. Useless for me. But yesterday a sweet cracker invaded it again and left behind about 240000 non-unique combinations of user+password he was using to invade others. They […]
Although WordPress 2.7 is almost only eye candy, it is great useful eye candy. The user interface is much much more practical, AJAXed, nice and fast. I recommend an immediate upgrade. It worked flawlessly with my complex homemade theme, my homemade plugins, plus all other plugins I use throughout my blog.
Spam fighting is a difficult job. Many spammers are too smart for Akismet and I was spending too much time cleaning comment spam. Captcha-based anti-spam methods are ok but they hurt too much the usability and user experience. Then I finally found Yawasp WordPress plugin that implements an innovative anti-spam method. It makes the comment […]
I love to see crackers attacking my computers. I even wrote a Linux Magazine article about a successful invasion (portuguese). Since recently, I leave a virtual machine with an easy password ready to be attacked, just to see these crackers’ leftovers, their rootkits and what they’ll do once they brake into my system. Guess what. […]
Pay attention to this screenshot. This is Mac OS running as a VMware virtual machine. Pretty cool as a proof of technology. But let me tell you, this is quite a useless virtual brick. The UI is extremely slow. I had to remove the background to improve it a little bit but couldn’t resize to […]
Yesterday I met a colleague at IBM Brazil that moved to a world wide position. He is now living in Manhattan, New York. His everyday routine, as most Information Workers nowadays, is to talk to people, make phone conference calls, e-mails, design and communicate strategies, make some data consolidation and reports, instant messaging, etc. Since […]
I was oweing this for the lovers of M. C. Escher works. Last July I visited the wonderful Escher Museum in Den Haag, Holland. One of my preferred works is the Print Gallery where a painting gets mixed with the surrounding real world in a precise geometrical way, as you can see bellow (borrowed from […]
This is the 12 weeks plus 4 days ultrasound result of our baby. We don’t know yet if its a boy or a girl. Stay tuned, it will be revealed in the next one. He is growing fast and we are looking forward for his arrival in february.

I just participated in very successful proof of technology with Siemens OpenScape video conferencing products. We made a point-to-point SIP high definition video conference over a local area network. Another test used H.323 protocol. We also included my SIP-enabled Nokia E61i in the conference over the office WiFi network in a direct multipoint call simply […]
In September 1956 IBM launched the 305 RAMAC, the first computer with a Hard Disk Drive (HDD). Its weight was close to 1 ton and had a capacity of 5MB. So now please do not complain about the lack of storage in your 2GB pen drive.
There is this website called Brand Tags that lets people quickly tag brands that pop up in a web 2.0 style. Then you can also browse brand names and see their tag cloud. For example, Linux is associated with “penguin”, “free”, “tux”, “cute”, “free” etc. Windows gets “computer”, “crap”, “crash”, “monopoly”, “sucks” etc. Apple gets […]
