The new feature is pretty awesome I think, though not the most obvious ever
It will however slowly become more and more obvious over the course of the next week, so: 10 virtual cookies to anyone who can figure out what the new feature is

Here's a hint: The extra feature requires an extra query per sequence for the next week, at which point we can reconsider increasing the update rate beyond 55 per hour.

Edit: Evidence a re-organization was in order: Despite adding the new feature and slightly more complicated logic, the new version is actually 8 lines shorter than the old one
Well getting the proper "recent progress" dates for every sequence is now complete, so that table should make for an interesting read. Note the FDB doesn't track dates before 2011-03-17, and also that the last week will be underrepresented because the column will show their total increase, as opposed to the most recent date.

In another news, a few hours ago, the DNS service appears to have been (hopefully temporarily) lost. Until that's fixed (I hope it's soon), the IPv4 address is here.

One of my graphics cards fans is broken, and then for whatever reason my computer lost power for a few seconds, then 15 minutes later I smelled something like burning rubber. I decided to leave it off overnight. Sorry

As pointed out elsewhere recently, the site will be down most of today; it should be up again by 0000 UTC at the latest.

Depending on the RMA and how I can do without my graphics card though, the page may not get any updates.

Would it be possible for you to take daily snapshots of the last-term-size and cofactor-size tables? I'm taking snapshots roughly fortnightly into an Excel sheet, and so can plot the distributions and watch the peak move down the python, but it might well be quite a pretty animation to watch it move on a timescale of days.

In the last five weeks, the average last-term-size has grown by 0.6 digits and the average cofactor size by 1.8 digits, suggesting we should get to average-last-term 120 digits by Christmas.

You or I could write a script to parse the data here ("aSizes" and "aCofacts") into whatever form you desire (CSV?). If you want me to do it, how should I get the snapshots to you? Make them available on the webpage somewhere? Automatically upload it to your FTP server? (Is that even possible?)

Fantastic; I've set myself up a crontab to pick up that file daily. Now all I need is a sufficient supply of round enough tuits to produce the animations ...

Default BSoD, what a lovely color scheme

Every time I visit this web page, I reach for my heart and then for my revolver.

How on earth did you manage to get the webpage theme so darn close to the blue screen of death?!

I (really really really) like blue!

As I've said before, I'll change the colors if someone suggests an alternate scheme.

You know, it had been a part of my plans to produce charts of the various tables, but the only decent Python plotting lib I found was matplotlib, and Python 3 support is still in beta (and at the time was still under active development). When it comes out of beta, I'll look into doing the graphs serverside... the obvious "corollary" would be animations as well, though I have no clue how to do that.

In the meantime, would you also be willing to record the length/guide tables ("aLens" and "aGuides")? They'd be pretty fun to see animated.

Edit: Apparently matplotlib also does animations as well.

It's around 1174 now, about 22/3 months later.

Just so you know, my page will probably be inaccessible from ~0000 UTC to (whenever I go to bed + 5)%24 UTC.

Not sure if this is helpful, but when I get sequences, I base them on the value I last got. So for example, for 276 I call:

wget "http://factorization.ath.cx/elf.php?seq=1318317059659669408240038846262480443602748610435445388542986041125974944748075928636239695427694073168827641
38573827680383355306759333640241337963062754830971836250952068019746298&type=1" -O final_276.elf

This gets me the NEW values only. In general, I can call this for all 47941 sequences (number of all open seqs less than 5 million) without hitting the limit. I only do this rarely (it takes a long time to run) but most sequences are the same so there is only one line to get so not a huge strain on the DB.

It also gets past previous data base errors because it doesn't get the bad bits each time. It is vulnerable to new database errors (to get past that I have a program to append the new lines and can then use aliqueit -t to check the full elf).

You would need a way to get the seq number and the current last value and to run the above calls. In my case, my stats program generates a bat file for me to run (the program actually does 3 things, generate the stats and bat file, append the final to the existing elf, and check for merges so I can update the current open sequence list)

As a side note, someone has been working on the 1-5 million range as they are all up to around 70 digits. That is why I extended to 5 million. Would make your table too big though.

Interesting fact: It takes a bit over 6.6 billion bytes to represent all the sequences in text/elf format for seqs up to 5 million with duplicates removed (sequences end when they merge). Of course this is always growing as more of each sequence is discovered.

Edit: One thing to mention is that I use the last full line in the elf for above and not the partially factored one, so I end up with elf files with at least 2 lines - the full and partial. It should also work with the final value though and give one line like I mentioned above.
