RE: Collection of HHC programming contests and other useful documents
To be fair, between the two of us that only represents about 31 downloads of my site over 9 months, so I still maintain that there is very little interest.

As a result, I won't be updating the torrent again until 2019-01-01; I think once-a-year updates are sufficient.

update 201809 released with delay.

magnet:?xt=urn:btih:6c7a3ffe2ff90942f1d5348ff5fe94191d6cbaab&dn=hp_calc_torrent_u201809

Quick update. Actually I collected some more material (although not as much as before, also because suggestions are lacking) but in those days my NAS (a qnap TS 431 P) lost an hard drive, so I have to first solve that then I may find the time to release the next update.

For this the p2p is gold. Even in the case I lose my content, I can hope to download it again. A shared backup.

I rebuilt my file server sometime ago and realized recently that I was not running Transmission (my torrent client of choice) to support serving these files.

As there is only one peer, and I will soon be the second, we need more!!

I've been seeding most of the torrents for about a year, but my Internet connection is unfortunately only 5 Mbps so I can't help much.

AT&T has fiber on the poles right by my house that should get me 1 Gbps like you can get everywhere else in the city, but for whatever reason, they don't recognize any address on my specific block as valid for fiber. So my block and my block alone is stuck in the 20th century.

Municipal fiber is probably 2-4 years away for me in my town, some neighborhoods are being installed this year. For now I have 40 mbit down, 5 mbit up.

Fibre is just a pipe dream for most people in the UK. We have one of the worst broadband networks in the world and most people have to make do with ADSL with around 4 megabits/s downlink and maybe 1/10th that uplink. Some more rural areas don't even have that.

There are only 10 types of people in this world. Those who understand binary and those who don't.

My Nas lost the disk with the torrents (raid 1! 1 disk died and for the other slot got the sata connector defective) . So I have mine (the hpcalc torrents) but I have to redownload the others (hp41, hpcalc.org and so on).

Also for such files, that actually should be always be around, rather than "download, remove from the torrent client", the speed doesn't matter much. Eventually it will be downloaded.

The situation is

There are plenty of people that should be thanked for their work of assembling or digitalizing or keeping around stuff about hp calculators, calculators, technology and knowledge in general.

Only I wanted to leave a line to thank SlideRule, who for months is leaving here and there links to a lot of papers, articles and resources related to hp calculators and they* are not frustrated by the lack of response of many of their posts (thing that frustrates a lot of people nowadays). SlideRule I appreciate your efforts and I am impressed. Quality builds really over time, although silently.

I'm not quite half way through my existing archives: hardest part is finding current &/or updated links/urls/etc for many of the remaining publications.

Small update

update 201810

magnet:?xt=urn:btih:ee8c8856fa2bd0df08a8d8844c97eb70b35f4d34&dn=hp_calc_torrent_u201910

Question. Where the hhc2019 contest uploaded somewhere? With a brief search I didn't find them. Thanks for your help.

RE: Collection of HHC programming contests and other useful documents
Magnet URI in the first page updated, as I had finally the time (after months !) to fix a bit my homelab.

Now I am redownloading and sharing the hpcalc and hp41 torrents (info: https://www.hpcalc.org/torrents/ )

Once again suggestions are welcomed and I hope somewhen to have more time. The backlog of things I want to do and threads to read is getting again too large. sob.

Oh yes, please stay healthy (stay at home, keep moving, eat healthy) in the times of covid 19. Impressive what is happing in the world, not even fiction could describe this.

RE: Collection of HHC programming contests and other useful documents
A question for eric, regarding the torrents shared here: https://www.hpcalc.org/torrents/

I downloaded them again but it seems that in the torrents the DHT and the peer exchange are deactivated. Only trackers are activated. (to see those options: right click on the entry in the torrent client, then properties or settings)

I cannot force to activate them unless I create a new torrent, making a duplicate with another hash.

Those two options are the core of a p2p distribution. Trackers are like a telephone book but if they go down or they are unreachable, peers won't find each other. And I notice this indeed because sometimes the trackers aren't reachable from my client. This leads to see "no activity" because the others cannot connect, even if they would like to.

Could the DHT and peer exchange be activated? At best even the "local peer discovery".

Normal torrents (the one I collect in this thread for example) have the options activated.

I don't know what that means. I am very unfamiliar with torrents in general. If I need to remake the torrents, if you could walk me through the steps necessary with uTorrent I can do it. When I made the existing torrents I just left the defaults on things and assumed that would be fine; I guess I was wrong.

As you can see, "Enable DHT" and "Local Peer Discovery" are disabled in the properties:

The defaults are fine as long as the trackers works but over time trackers disappear so the DHT is crucial, if on the forum there is a magnet link, because then the client - slowly - will find its way to the file.

Please enable every option in the "other settings" in the next release, if you can.

Meanwhile my little system with torrent died and the wasps tried to make a nest near it, because it is in a cabinet on the balcony. As soon as it doesn't work it is not warm enough to keep bugs away!

I'll try to fix it but it may take some time as - as you may noticed - I have in general very little time since 2019 (too many interest, too little time and kids/other people. Kids first!). The torrent will come back and I hope I will announce it. I miss the time when I went through the forum reading all the unread posts. Well I hope it will get back and as I read - at the time - the existing 76 pages of topics in general (well, ignoring threads with unappealing titles), I hope to do it again soon.

Stay safe and enjoy the forum/discussions also on my behalf!

PS: yes I know I have a lot of threads to update, at least those about benchmarks and list/vector processing and userRPL. They can still grow and then hopefully i will catch up with the updates.

RE: Collection of HHC programming contests and other useful documents
In the past I would have fixed the problems in my homelab in a week at most, maybe two. Nowadays with other priorities (the time is the same, the skill is smilar, the priorities change) I took some months.

Anyway at least it happened. The files are again there, at least from me, and I slowly share again the files from the hpcalc.org collection as well. The first post is updated. Nonetheless many of those files have "broken" trackers and it seems it takes time to find peers on the DHT with the files.

For the rest I still have to catch up with what you all write and publish. Please don't stop because somewhen (I hope soon) I'd like to read a lot of interesting things!

Ah yes, as usual suggestions to what to include (if not to me, to Eric and his hpcalc.org collection) are welcomed!

RE: Collection of HHC programming contests and other useful documents
After waiting some weeks, the hpcalc torrent didn't find any peer and the DHT was disabled. Thus I got the data through the static servers and created alternative torrents with the DHT enabled. I hope it may help someone.

See the first post for info. If Hpcalc torrent enables the DHT, we can drop this alternative and share the original. This because the original trackers, at least from my network, do not work and thus one gets no peers.

(Why alternative? Because unfortunately every torrent is more or less unique, unless the data is exactly the same, when there are a lot of file, it can happen that something diverges)
