A Modernized Metric Clock

November 22, 2023 by Bryan Cockfield 60 Comments

Much to the chagrin of many living in North America who still need to do things like keep two sets of wrenches on hand, most of the rest of the world has standardized to a simpler measurement system using metric units exclusively. The metric system is widely adopted worldwide, but we still use a base-60 system for timekeeping that predates the rest of the metric system. The French did attempt to “decimalize” timekeeping as well with the French Republican Calendar at around this same time, but this “metric” timekeeping system never caught on particularly well. It’s still an interesting historical tidbit, and [ClassTech] built this modern metric clock to explore it a little more.

The system itself uses ten-day weeks, ten-hour days, and 100-minute hours which makes it more in line with the base-10 system common to the rest of the metric system. But this means that a second in the French Republican system actually works out to a little less than one and a half SI seconds, meaning that a modern timekeeping computer needs to do a little more math to display the correct time at the correct interval. [ClassTech] is using a Particle Photon IoT processor getting the time from a NTP server, converting it to “metric time”, and displaying the time on a Nextion touch display.

While the device is reported to update the time once per second, we’re not sure if this is every SI second or every French Republican second. Either way, there are plenty of reasons this timekeeping system never gained widespread adoption, and a surprising one is that timekeeping tends to be easier in a base-60 system due to its capability of having more divisors. Many other reasons are less technical and more cultural, and timekeeping tends to be surprisingly difficult to coordinate even among shared numbers systems and languages.

English Words In French Gaming? Non Merci!

June 1, 2022 by Jenny List 111 Comments

Are you a gamer? If you’re French, it seems that you shouldn’t be using so much English in pursuit of your goals.

It’s a feature of an active language, that it will readily assimilate words from others. Pizza, karaoke, vuvuzela, parka, gateau, schadenfreude, they have all played their part in bringing a little je ne sais quoi into our everyday speech. This happens as a natural process as whatever the word is describing becomes popular, and sometimes these new words cause a backlash from those who see themselves as the language’s defenders.

Often this is a fringe activity such as the British politician who made a fool of himself in a radio interview by insisting on the now-archaic Wade-Giles “Peking” rather than the vastly more common Pinyin “Beijing”, but for some tongues it’s no laughing matter. Nowhere is this more the case than in the Francophone world, in which the Academie Francaise and the French and Quebecquois governments see themselves as very much the official guardians of French. And now it seems that the French ministry of culture have turned their eyes upon gamers.

It’s nothing new for words associated with technology to fall under this scrutiny, a quarter century ago in the CD-ROM business it was de rigeur for localized discs to talk about le logicel, l’ordinateur, and telecharger instead of program, computer, and download. The talk of the industry was that Sony refused to do this for PlayStation consoles sold in Quebec during the 1990s, and thus all their sales in the province had to be under-the-counter. But there’s a sense from reading the reports that this intervention is a little clumsy; while it’s easy to say logicel we’re not so sure that jeu video de competition or video game competition for e-sports and joueur-animateur en direct or live player-animator for streamer aren’t just too much of a mouthful for easy adoption. For the first one, we can’t help remembering that sport is also an everyday French word, so couldn’t they have come up with something less clumsy such as reseau-sports or network-sports?

Here at Hackaday more than one of us are unrepentant Francophiles, so the evolution of French words in our field is of interest to us. Habitez-vous en France ou Quebec? Donnez-nous votres idees dans les commentaires! (mais en Anglais s’il vous plait pour les Americains, excusez-nous)

Tiny Operating System For Tiny Computer

June 28, 2021 by Bryan Cockfield 12 Comments

Before the World Wide Web became ubiquitous as the de facto way to access electronic information, there were many other ways of retrieving information online. One of the most successful of these was Minitel, a French videotex service that lasted from 1980 all the way until 2012. But just because the service has been deactivated doesn’t mean its hardware can’t be used for modern builds like this Arduino-based operating system. (Google Translate from French)

Called ZARDOS, the operating system is built to run on an Arduino MEGA although a smaller version is available for the Uno. The Arduino is connected by a serial cable to the Minitel terminal. It can take input from a keyboard and PS/2 mouse and displays video on the terminal screen with the same cable. There is functionality built-in for accessing data on a cartridge system based on SD cards which greatly expands the limited capabilities of the Atmel chip as well, and there is also support for a speaker and a Videotex printer.

Even though the build uses a modern microcontroller, it gives us flashbacks to pre-WWW days with its retro terminal. All of the code is available on the project site for anyone looking to build an Arduino-based operating system, although it will take a little bit of hardware hacking to build a Minitel terminal like this. Either way, it’s a great way to revive some antique French hardware similar to a build we’ve seen which converts one into a Linux terminal.

Thanks to [troisieme_type] for the tip!

France Proposes Software Security Liability For Manufacturers, Open Source As Support Ends

February 22, 2018 by Jenny List 58 Comments

It sometimes seems as though barely a week can go by without yet another major software-related hardware vulnerability story. As manufacturers grapple with the demands of no longer building simple appliances but instead supplying them containing software that may expose itself to the world over the Internet, we see devices shipped with insecure firmware and little care for its support or updating after the sale.

The French government have a proposal to address this problem that may be of interest to our community, to make manufacturers liable for the security of a product while it is on the market, and with the possibility of requiring its software to be made open-source at end-of-life. In the first instance it can only be a good thing for device security to be put at the top of a manufacturer’s agenda, and in the second the ready availability of source code would present reverse engineers with a bonanza.

It’s worth making the point that this is a strategy document, what it contains are only proposals and not laws. As a 166 page French-language PDF it’s a long read for any Francophones among you and contains many other aspects of the French take on cybersecurity. But it’s important, because it shows the likely direction that France intends to take on this issue within the EU. At an EU level this could then represent a globally significant move that would affect products sold far and wide.

What do we expect to happen in reality though? It would be nice to think that security holes in consumer devices would be neutralised overnight and then we’d have source code for a load of devices, but we’d reluctantly have to say we’ll believe it when we see it. It is more likely that manufacturers will fight it tooth and nail, and given some recent stories about devices being bricked by software updates at the end of support we could even see many of them willingly consigning their products to the e-waste bins rather than complying. We’d love to be proven wrong, but perhaps we’re too used to such stories. Either way this will be an interesting story to watch, and we’ll keep you posted.

Merci beaucoup [Sebastien] for the invaluable French-language help.

Liberté, Égalité, Fraternité, AZERTY

April 20, 2016 by Brian Benchoff 30 Comments

In the US, we don’t hear much about computing from beyond the Anglosphere. We’ve seen some home computer clones from behind the iron curtain, but getting any information about them is hard. If you find an old keyboard with a QWERTZ layout, or even a few Cyrillic characters, in the States, it’s a rarity. To date, the only French computer on Hackaday is an old Minitel dumb terminal. To help rectify this, [Jeremie Marsin], [Thierry Mazzoleni], and [Jean Paul Mari] from Quebec brought the best of the French computing revolution of the 1980s along to this year’s Vintage Computer Festival East

The evolution of the reigning champion of this exhibit begins with the Micronique Victor Lambda, a licensed copy of a purely American computer, the Interact Home Computer System. This computer featured a 2 MHz 8080A, 8 or 16 kB of RAM, and was quickly discontinued. The French company Micronique quickly bought the original designs and remarketed the computer in France.

In a few short years, Micronique took this design and turned it into the Hector. This machine featured a 5 MHz Z80, 48 kB of RAM, high resolution graphics (243×231 at four colors) and included BASIC and Forth interpreters.

The Victor and Hector were the best home computers at the time, but for every Commodore or Apple, you need a ZX Spectrum. France’s version of this tiny computer with a terrible keyboard was the Matra Alice 32, a computer with a 1 MHz 6803, 16kB of Ram, and a real 80×25 text mode. The Alice is heavily based on the American TRS-80 MC-10, with a SCART connector and an AZERTY keyboard.

The weirdest computer [Jeremie], [Thierry], and [Jean Paul] brought out? That would be the Excelvision EXL100. The 1980s, for better or worse, were the times of the Z80 and 6502. The EXL100 was running something completely different. This home computer used a TMS7020 CPU from Texas Instruments, a speech synthesizer, and a wireless keyboard. Very strange for the time and relatively inexpensive; in 1984 this computer cost only ₣3190, or about $550 USD.

[Jeremie], [Thierry], and [Jean Paul] had an exhibit that presented the best the Francosphere had to offer to the computing world in the 80s and 90s. We haven’t seen enough early computers from outside the US, so we’re happy to have met these guys at the 11th annual Vintage Computer Festival East.

Man, Stranded In The Desert, Makes A Motorcycle From His Broken Car

May 21, 2012 by Caleb Kraft 190 Comments

The original story is in French, and the Google translate is very rough. Please forgive us if we don’t get this completely accurate.

While traveling through the desert somewhere in north west Africa in his Citroen 2CV , [Emile] is stopped, and told not to go any further due to some military conflicts in the area. Not wanting to actually listen to this advice, he decides to loop around, through the desert, to circumvent this roadblock.

After a while of treading off the beaten path, [Emile] manages to snap a swing arm on his vehicle, leaving him stranded. He decided that the best course of action was to disassemble his vehicle and construct a motorcycle from the parts. This feat would be impressive on its own, but remember, he’s still in the desert and un-prepared. If we’re reading this correctly, he managed to drill holes by bending metal and sawing at it, then un-bending it to be flat again.

It takes him twelve days to construct this thing. There are more pictures on the site, you simply have to go look at it. Feel free to translate the labels and post them in the comments.

Update: From [Semicolo] in the comments

You got the translation right, but there’s not just a swing arm that’s broken, there’s a frame beam broken too (not sure about the exact term, one of the 2 girder of the chassis).
He’s not far away but he has a lot of tools and other hardware that could be stolen if he leaves them unattended.
