"Massage Passing" library?
by William Park 13 Sep '17

13 Sep '17

Hi all, I'm looking for keywords to search for... I have various local peripherals that I need to read and write. From top of my head, I'm thinking 3 ways: 1. Use select(2) (and friends) to round-robin the peripherals. 2. Each peripheral is serviced by a separate thread, and main thread does the business logics. The peripherals don't need to talk to each other (but this may change). 3. Each peripheral is serviced by a separate process, and they pass "messages". This option is what I want to investigate. So, do you know any "message-passing" scheme, framework, or library that I can look up? I'm not talking about OS or kernel level. More at application level. -- William Park <opengeometry(a)yahoo.ca> .

Myles's Open Data Talk
by Stewart Russell 12 Sep '17

12 Sep '17

Great talk from Myles tonight. Canada is trying to be better about open data, but it has a long way to go. There are open PDF scraping tools, but they tend to be very limited in domain. It's always fun when you get data that must be published, but there's no stipulation that it's usable. The best example of this is the US Armed Forces Appropriations data that's published in a single giant PDF every year. While it genuinely does publish details of every military contract, it uses a fiendish set of page templates to make it very difficult to parse. I ended up making minor headway consider each page as geodata, with each page a map with words at given coordinates. Cheers Stewart

Voynich Manuscript update
by Richard Weait 09 Sep '17

09 Sep '17

Now, a claim that the Voynich Manuscript has been "decoded". Well, "read" really, not decoded. It was in shorthand, of a sort. https://arstechnica.com/science/2017/09/the-mysterious-voynich-manuscript-h… William Porquet did a talk on the subject at TLUG a few years back.

NOT: Re: From BTRFS to what?
by Alvin Starr 07 Sep '17

07 Sep '17

Wow. got into a bit of a snitfest with dhaval.giani over this one. Now to the completely unrelated part. I have been thinking about a project and I would like to bounce it off you. A client came to me asking about helping him setup an Etherium mining server pool. This got me thinking. In its simplest sense the process is power in ..... ETH out. The biggest cost is power then cooling to get rid of all the head from the GPU's. What if you glue a GPU with very little extra hardware to the back of a solar panel. Stick it out in the sun and let it calculate 8-10 hours a day. Put a big heat sink on the GPU and it should be able to stay cool enough just from air cooling Take a few thousand of these and set them out in a sunny place and you would have a coin generator. Once the hardware is paid for then the operational cost would be close to 0 but for some glass cleaner and rags. They would need to be networked together but it does not have to be high speed. It could be a low power mesh to an edge that connects via something as simple as cell phone data. Solar panels cost about $1/watt and there is no ongoing cost but power here costs about $0.08-0.16/KWH. On the face of it there is a 3 year payback for the power but if you add in 30% extra power to run cooling and the building costs for housing the mining pool.

From BTRFS to what?
by William Park 06 Sep '17

06 Sep '17

I have BTRFS filesystem used for backup. I chose BTRFS because it can consolidate old leftover harddisks of various sizes into one big pool, and it can do "snapshot" which is pretty cheap way to do daily, weekly, monthly backups. Now, I read (it's an old news, though) that BTRFS is being "deprecated" by Redhat, and presumably others will follow. What do I do? What do you guys plan to do? -- William Park <opengeometry(a)yahoo.ca>
