The HAT that you see in this photograph is Astro Pi. The European Space Agency tells us it's the most advanced educational payload they’ve seen, it's bristling with sensors, and we're sending it to the International Space Station with British ESA astronaut Tim Peake.

We're working hard to get them manufactured in volume, so schools will be able to use the exact same hardware in the classroom. Even better, UK schools will be able to win it in the Astro Pi competition: students will have the chance to have their code sent to the ISS so that Tim Peake can run their experiments and applications in space!

Registration for secondary schools is now open at http://astro-pi.org/secondary-school-competition/, and primary schools (whose students are asked to come up with ideas, but not necessarily their own code) can enter at http://astro-pi.org/primary-school-competition/.

Read more in our first mission update, now on our blog at www.raspberrypi.org/astro-pi-mission-update-1/.

well, they all come from china...

the new one was a little different though. After not getting an IP through DHCP it opened a troubleshooting menu with a radio button that read: "I will turn my modem off and on again and then try other things." (with a few grammar/spelling mistakes)

Replacing an SSD with an HDD had the unexpected side effect of increasing my power consumption by nearly 40% on my X220. Used to be 10W, now its nearly 14W most of the time.

Perhaps I ought to mount \var again on SSD again, as it apperars writing to log prevents the HDD from spinning down.

+gerald schenk why is var on the storage HDD it should be on the SSD boot only drive. Firstly look at the noatime parameter for your fstab. Also look at putting 8GB RAM in then using a tmpfs RAMDISK, there are ways to use it to cache the logs which are written to the SSD at shutdown. You could also set up the HDD as /home.

On Lemons and their use in Baking

Baking recipes often require the use of lemon peel of unwaxed lemons. There is a specific reason for this, and great care ought to be taken not to use treated lemons.

Not the wax is the problem here, but rather the fungicide treatment that accompanies the waxing. In Europe it mostly is done with thiadibendazole. Thiadibendazole is not very soluble in water. When you peel the lemon and eat it, you will only incoroporate a very tiny amount. However it is very soluble in oil, and it is solved in the wax coating and much more importantly in the aromatic oils in the lemon peel. Washing the latter away would make using the lemon peel pointless.

Now for the amounts, when talking about toxicity the dose always is the most important aspect. Within the European Union it is permitted to have 0.01 mg/kg in fruit juices. I.e. it is considered save to consume that amount. On the other hand it is permitted to have 5 mg/kg on lemon peels.[1] This is a 500 times larger concentration. Even if you would wash of 90% of the thiadibendazole from your lemon peel, you would have 50 times higher concentrations than permitted for consumption. This is perfectly OK when you eat the lemon.

Wash it with warm soapy water and you do not have to worry at all when peeling or cutting it. Even putting such lemons into a soft drink is certainly not problematic (after washing!).* However peeling or zesting the lemons to eat the peel is an entirely different matter.

The only way to go is to use untreated (not unwaxed!)** or organic lemons.

* This is different in cocktails, when it has a high alcohol content it will solve the thiadibendazole very readily.

** There is no reason whatsoever to worry about the wax, if it bothers you mix the lemon zests with a little bit of alcohol. This is also recommended to extract the aroma. Gin is lovely for that purpose.

Now that the evenings are cold and dark...

... the new version of this wonderful game comes just at the right time.
 
Simutrans 120.0.1

Prissi announced the release of a new version of Simutrans at the international forum:

_This is version is mostly a bugfixing release, aiming at a stable experience with the climates which neighbour each other, lakes and two levels of slopes. Currently these features are acknowledged by nearly all major pak sets (with the exception of pak64.german).

Just remember: waypoints do no longer act as signals. If you exploited this feature, then you will need rebuilding these routes._

Lesya Ukrainka (Леся Українка) Monument in Toronto, Canada

From the late 19 century on, emigration of Ukrainians was very significant. There are often distinctive waves of emigrants, driven by 'economic'* or political reasons. Canada received several strong influxes, in shortly before the great war Ukrainians settled the continental provinces. The metropolitan centres, in particular Toronto, received a significant influx of rather well educated immigrants, especially after shortly after the second world war, and in the 70s.

While the traces of immigrants to the mid-west are after four or five generations (and perhaps due to stronger assimilation pressure back then) not obvious. The first, second and third generations of the more recent immigration to Toronto have formed an active Ukrainian culture and diaspora in Toronto. Its heart is the area immediately north and north-west of High Park (which is today a rather affluent area).

This statue at a prominent place in High Park, could be an indication that her literature work still is of importance to many. There is also an annual celebration of the Literature of Lesya Ukrainka in the park.


*The fourth Saturday in September is the Holodomor Memorial Day of the Province of Ontario. There is a wide consensus in Canada to identify it as genocide.
