Beauchat/Uwater Aladin PRO dive computerWhile buying some used kit on the classifieds, I was handed a grey Beuchat (later Uwatec [today Subapro]) Aladin PRO 3 button diving computer from the mid-nineties. Through a bit a research, I learned that it had first came out in 1988 and was still to this day revered by some in the diving community as a sturdy, reliable no-frills device. Obviously, the manual was no longer available for download and it’s only after asking someone (many thanks Geoff Nelson) on an old thread on scubaboard that I finally got it.

Exploring an abandoned convent

Today, the sun was out and bright in perfectly clear skies, in other words, not studying day. Having wanted to check out the Saint-Anne-de-Beaupré basilica for a while, I figured this was a good enough reason to leave my books for an afternoon and get out of the city.

My tour of the basillica and the other smaller attractions in its vicinity only yielded mild satisfaction. The basilica itself was impressive, but lacked the imposing and solemn feeling you’d expect from such an important place of cult. Though well landscaped, the grounds around it were nothing more than facilities catering to the many pilgrims that come here each year, but on my way up the hill behind the basilica, I noticed another building of religious function hiding behind a curtain of vegetation. It was a monastery, at least that was what the sign on the main entrance indicated.

Convent of the Redemptoristines entrance

Nature was clearly well into the process of reclaiming its lost territory and the whole building looked decidedly empty. On closer inspection, windows were broken and the masonry was starting to fall apart in places. That’s when I noticed an opened door. I walked around the building to see if I could spot any sign of human activity and after noticing many more open entrances, I took it as an invitation to go inside.

Convent of the Redemptoristines refectoryI entered through the refectory, made my way to the chapel and then proceeded to explore each and every floor all the way up to the roof. It was eerie. I’ve been inside abandoned buildings in the past, but the fact that this one had been a place of worship and religious devotion made the whole experience somewhat creepier. I could feel my heart pounding, I was super alert and watching every single step I took. For a good hour, I walked around this empty building that given it’s size, must have been occupied by well over an hundred in its heyday. I took many pictures during my tour but only a handful turned out OK enough; too bad I’m a poor photographer because the place was extremely photogenic. Aside from some furniture, the place had been gutted empty, even the wooden hand rails were gone. Not that I intended to steal anything, even if the site had been abandoned, it still had owner so nothing in there was mine to take, but I was certainly hoping for more religious paraphernalia.

Once out, I went back to the village and asked some locals what they knew  about the monastery. They told me it had been built at the beginning of the last century and was occupied for most of its history by nuns but otherwise, none were exactly sure how such a place became so derelict or what fate was awaiting it. Back home, a quick search on the web turned up heritage listings (1, 2). The monastery, built in 1906, had been a convent for the Redemptoristines nuns. Owing to their declining numbers and means to maintain and occupy their huge home, the nuns relocated near Montreal in the mid 1990s. After a string of occupants and dwindling interest in the property, it became too big of a burden so the owners, the Redemptorists monks, stopped heating the building (and doing any maintenance whatsoever on it). This Flickr page from someone who, just like me, had sneaked inside the convent uninvited, shows what the interior looked like before it was definitively abandoned in 2014. It’s staggering to see what two years of complete neglect does to infrastructure and how fast nature reclaims her rights.

There are plans to convert the property to a funeral home but thanks to it’s peculiar architecture (typically 1900s), the exterior has been declared heritage so at least the outer part of the convent should be preserved in that capacity for a while. However, given the size and age of the building, I entertain many doubts in its long-term survival as I don’t think a small regional business or city can afford the upkeep costs of such a place. Hopefully, that small Wikipedia article I wrote on it will preserve some of the memories.

Moving Linux on a windows drive for dual booting

README! There are many use cases for dual booting and guides for achieving it, this one concerns moving an existing Linux to a drive on which Windows is already installed and dual booting them. In other words, you will be combining existing Windows and Linux systems to coexist on the same hard drive.

I’ve been using the same hard drive for a while and transporting it from laptop to laptop whenever one would fail me (you can do that with linux). Now, after 8 years, I was fearing it was the actual hard drive that would break next so this time, I had to move my actual operating system to another physical disk.

Wanting to be able to dual boot into windows as well, I was stuck in a scenario for which there was not much help on the web. Here’s what I did:

  1. Resize your Windows partition using the disk management tool to make room for Linux and its swap. The new Linux partition must be larger that the one you are moving from.
  2. Reboot to a Linux live CD or GParted and create a bootable Linux and a swap partition (they must be primary) after the Windows partition.
  3. Clone you existing Linux OS partition from the old hard drive to the new.
    1. Plug in your old drive (external SATA, external disk case, extra hard-drive bay, etc.) but leave it unmounted.
    2. dd if=/dev/sdXY of=/dev/sdWZ bs=1M

      where XY is the drive letter and partition of the Linux OS you are moving from and WZ those of the partition you are moving to.

    3. Wait for a while, depending on the size of the partition, this could take a bit because you are cloning every single byte from one partition to the other. In my case, it tool a good solid two hours and half.
  4. Unmount and disconnect your old Linux OS hard drive. In case something goes wrong, simply popping it back in your computer will restore your setup just the way it was before.
  5. Mount your new Linux partition.
  6. From within the Live CD, restore the GRUB2 bootloader by executing
    grub2-install --root-directory /mountPoint /dev/sdW

    where mountPoint is where you new Linux partition is mounted and sdW is the drive where it resides.

  7. Since the partition’s GUIDs have changed you need to update the /etc/fstab file on your Linux with the new ones. Any file editor will do. Look up the new GUIDs for your new OS and swap partitions by running
    ls -al /dev/disk/by-uuid/
  8. Remove the live CD and restart the computer.  From within GRUB2’s boot menu, you should only see your Linux and not Windows, that’s normal. Boot your Linux OS.
  9. Run
    grub-mkconfig -o /boot/grub2/grub.cfg

    GRUB2 will scan your hard drive, find the Windows install and create a new boot configuration file. Now, when you reboot your machine, you will see Windows within the boot menu menu entries.

  10. Finally, since the size of the underlying partition holding your Linux installation has changed, the size of the file system has to be updated as well:
    resize2fs /dev/sdW

Done! Moving operating systems around and getting them to cohabit alongside each other is tricky and far from being straightforward so I hope this guide worked for you. You will most likely have to adapt it to your own situation and if you feel something you did could benefit others, please comment.

Apple wood wine bottle stands

wine bottle stand

Two years ago, we had to fell an old apple tree from my parent’s garden. Wanting to experiment with this unusual variety of wood, I gathered the best logs and took them to a sawmill to have planks made and let them dry for a year in a shed.

Fast forward to last Christmas, not wanting to buy gifts and being left with very little time to come up with something before the 24th, I had the idea of making balanced wine bottle stands for everyone out of that old apple tree. It’s a simple project, it’s can be made in batches, can be gifted along with an actual bottle and would make an awesome souvenir of that tree we had so much fun climbing onto and playing around during our childhood.

Apple tree is a pain to work with, the grain is highly irregular and convoluted and the density of the wood varies widely within the same piece. However, the end result is spectacular, especially on the more weathered down parts of the tree, which have turned multiple shades of pink, brown and black due to parasites and moisture. From log to plank, there was a huge amount of loss but through keeping the project small I managed to get something workable out of all that wood.


How to program a new Toyota transponder key

In need of an extra key for your Toyota? Avoid the dealer, they charge an arm and a leg for a simple procedure you can do yourself for free. Searching the web turned up a couple of techniques, but the one that worked for me was found in a youtube comment by user Nazareth434.

My car is a Toyota Matrix 2005 but apparently this procedure is valid for several Toyota models and years. If it did or did not work for you please let me know in the comments. And if nothing including this procedure has worked for you, don’t despair, at least your copy can open doors. Attach the key to a concealed spot under you car and save it for the “oops I’ve locked myself out”situation.


First, you need a blank transponder key for your model and year. You can get one for 10$ or so through eBay or amazon. Then, have the key cut by your local hardware store and make sure it fits you ignition lock: you should be able to turn it all the way to the start position and hear the starter going without the engine turning on. With the master key (the black key, not the valet key, which is grey) and the copy in hand, install yourself in the driver’s seat and follow the procedure carefully. It took me about 30 minutes and many tries to get the steps right as there is timing involved. Persevere and and it should work.

  1. Insert the MASTER key in the ignition 5 times, leaving it IN the ignition on the 5th time. Do not turn the key. Don’t rush that step, do it slowly.
  2. Open and close the driver’s door 6 times, leaving the door closed on the 6th time.
  3. Remove the master key from the ignition. The security light should now be solid red to indicate programming mode. If it’s not, repeat from the beginning.
  4. Insert the new key in the ignition but don’t turn it. Do that step quickly as the computer only stays in this mode for a couple of seconds.
  5. The security light will resume blinking. After 60 seconds (maybe more, be patient), the light will stop blinking and turn off.
  6. Remove the new key, insert the master and turn the engine on and then off.
  7. Done! Test your new key. When you insert it, the security light should stop blinking and the car should start.

The theory

Its wrongly called programming a key but in fact, no key gets programmed by itself, its the car that gets programmed. Keys have an RFID emitter in them which outputs a unique identifier when prompted by the car’s anti-theft device’s reader upon insertion in the ignition. If that identifier is not in the car’s computer valid key identifier list, the car will not start.

What the procedure above does is putting the car’s anti-theft system in programming mode and then telling it that it should include the new key’s id in its list of permitted keys. This is done by doing a set of special steps with the master key in. If you possess the master key, chances are you are the master, but should you loose all you keys, there will be no way of starting the car again other than replacing the anti-theft computer; something the dealer will charge a lot for.
