FTP Server #2

 Pages:  1    3

axehandle - 16-5-2004 at 09:29

I'm hereby announcing the existence of another FTP server, containing
materials similar to those on Eliteforum's FTP, but (as yet) horribly unsorted.
The content amount at the moment of this writing is almost 10Gb. I
hereby thank the beta-testers most heartfully. Without you, it couldn't
have been done. I have had help with acquiring all the material. Those
of you who have helped me, through snailmail and email and uploads; you
know who you are, but out of respect for your privacy I'll not mention
you unless you explicitly ask me to.

The server lies on my dedicated firewall/fileserver at home. The specs
are:
10Mbit/s full duplex.
All filesystems are on RAID5 partitions under Linux, so if one disk
goes, no data is lost.

If you want an account, PM me for a Username/Password combination.
The host and port are DNS resolvable.
Host: species8472.dyndns.org
Port:21 (the standard FTP port)

My motivation for setting up this server is fourfold: 1) Keeping all
eggs in one basket is mad; 2) Having two FTP servers means twice
as many people can download things simultaneously; 3) My ISP permits
running my own servers; 4) I rarely use more than 1% of my available
outgoing bandwidth, and decided that I would dedicate it all to the
sciencemadness community.

I shouldn't have to mention this since I think it's implicit, given my
reasons, but I'm in <b>absolutely no way</b> trying to belittle the
great service Eliteforum has and is giving to the community. My <b>only</b>
goal is to improve the availability of chemistry material. Two servers means
twice as many people can download simultaneously, all other things being equal.

So, as I said, PM me for username/password pairs. Everyone is welcome.

If you want to upload stuff, do it in the "upload" directory (which is
the only write-permitted directory anyway).

Another note: No transfers are logged. You're pretty anonymous. Also,
the maximum number of connected users at any one time is restricted
to 20 --- this will keep downloads fast enough while still being a
reasonable number.

Also: Nobody will receive any special treatment. I welcome all. Leeching
is permitted, and uploading is encouraged, but not required.

A few words about material choice if you do decide to upload: I have little
interest in "warez" unless they are of a scientific nature (e.g. CAD programs,
chemistry and psysics utilities, rocketry ballistics programs, etcetera) or
are essential for making ebooks out of dead tree books. Common sense should
suffice, and I won't spank anyone for uploading something of questionable
value.

The same applies to videos. Only chemistry and/or physics related are of
interest. Simply put, a video of a successful rocket flight is welcome,
ordinary movies or porn of any kind are out.

Games are out. I want the bandwidth to be used for scientific purposes. The
same applies to sound files.

Ebooks, and the tools for reading and making them, are welcomed. They don't
need to be chemistry related. I think we all here like to read, no?

Oh, and by the way:

axehandle - 16-5-2004 at 10:12

Please report any anomalies. Running an FTP server is hardly rocket science, but I may have to adjust certain settings to make the experience more enjoyable, like timeout values etcetera.

Very good.

There cannot be enough ftp´s spreading information - never. ftp server are the backbone of the freedom of information.

Very good.

That was exactly why I started this project.
Btw, for you guys who have just tonight gotten your login information: How does it seem to work so far?

Quantum - 16-5-2004 at 11:16

For me the FTP is working well. I want to write some stuff for it but as of now I don't have much to say. I am making copper cloride but because of its other uses the method is covered very well.

vulture - 16-5-2004 at 11:29

Damn, we're good, yet another FTP server! Thanks axehandle.

I'd also like to abuse this post to make a request:

Could somebody please upload chemwindow to the FTP?

Thank You.

De rien.

axehandle - 16-5-2004 at 11:41

I've increased the maximum number of concurrent users to 30. That means that if all 30 slots are downloading with no bottlenecks on their sides, the DL speeds will be about 16kb/s. Acceptable, I think.

Great Job!

Tacho - 16-5-2004 at 15:11

Did you see that folks?

I quote:

"Also: Nobody will receive any special treatment. I welcome all. Leeching

This is an historical moment! I have tears in my eyes.

Let me know if there is anything I can do to help. I guess it's time to buy a scanner!

Mephisto - 17-5-2004 at 06:48

Great! Thanks a lot.

BTW: Is there a public account just for uploading?

No, and there won't be. Having one is opening oneself up to a DOS attack.

hodges - 17-5-2004 at 14:57

Thanks, Axehandle. I downloaded a good chemistry book that is 125 years old from your site. Its interesting how things have changed. There are experiments with energetic compounds that would never be described in today's chemistry books. They refer to various gasses as "permanent" because they have "never been liquified". Then they talk about some type of "anti-ozone" that is always produced during combustion and causes the particles of smoke to form a mist. Its interesting how some things were already understood pretty well 125 years ago (and the same explanations might appear in chemistry books today, with slight language differences), while others are way off base.

If there's an interest sometime I might upload some energetic material videos I have made during my experiments (small amounts of various thermites, NI3, explosive silver compounds, etc.).

FTP account

pdb - 25-5-2004 at 04:55

Axehandle, could you please provide me with an account using U2U ? Thanks;)

Aaaaarrgghh!!!

axehandle - 25-5-2004 at 05:12

Please make your account requests via U2U, not here --- this thread will be huge otherwise.

pdb: You already have an account. Check your U2U inbox again. Someone asking twice sends me into paranoia mode.

ISP problem

axehandle - 26-5-2004 at 09:46

My ISP is having a malfunction. As a result I lost Internet connectivity between approx. 12:00 and 19:47, local time. The problem could return, they haven't solved it completely yet.

Update: The problem was caused by some piece of broken hardware (it was a bit vague to say the least), and was corrected at 19:30, local time.

rsync

axehandle - 27-5-2004 at 13:11

Soon I will set up rsync so that anyone with a valid username/passwd combo can keep a mirror of the entire archive, now 9.0Gb. Is there interest for this?

KABOOOM(pyrojustforfun) - 31-5-2004 at 20:07

I have some gigabytes of chemistry journals. if anyone (with a decent connection speed or axehandle himself) wants them on CD u2u me... in return I wanna get it uploaded to the FTP

btw I'm scanning "Techniques and Experiments for Organic Chemistry" has anyone already done it?

Axt - 1-6-2004 at 00:08

There used to be an address posted in the first ftp thread (now deleted) by eliteforum that allowed you to access the ftp through internet explorer. I'd like to know what it was, as that was my only route into it. The address included the host, username and password. I asked Axehandle through U2U and recieved this -

ftp://axt@species8472.dyndns.org
You will then be prompted for the password.

But she aint working! Cant use another ftp thingy as I only have access through a university computer ... help.

Which operating system? I don't know of any OS (well, apart from macOS < 10, but I wouldn't call those operating systems...) that doesn't have a command line FTP client. Even windows does.

Invoke "ftp species8472.dyndns.org" from the command line (MacOS 10, win9x, win2k, winxp, solaris, linux, whatever) and you should be in, and be prompted for username and password.

The_Davster - 1-6-2004 at 14:59

I tried to upload some scans but it said "access denied", I am also unable to make a folder to put the scans in.

Ium - 1-6-2004 at 18:15

Most educational institutions that have an internal network with external internet access will be firewalled. The FTP browser must use different settings in order to get around the firewall and in some cases a password is required.

If you are using internet explorer as your FTP browser, go to

Tools > Internet Options
Click on the "Advanced" tab and select the checkbox for "Passive FTP" under the heading "Browsing". Then try again to access the FTP.

If you are using an FTP client such as CuteFTP or similiar, then look for the PASV or Passive FTP connection option in the settings for that particular application. Make sure it is selected and then try to access the FTP.

The above usually fixes the problem if you are behind a firwewall or have a DSL modem. It's worth the try. Thats all the advice I can offer.

[Edited on 2-6-2004 by Ium]

Axt - 1-6-2004 at 18:56

Invoke? ... lol ... you could explain that, but I dont think it'll help! As lum has said, the problem is on my end with a firewall or simular blocking access.

The browser wont let me access the advanced options, bloody restrictions.

I can only say that the previously mentioned address in the now deleted ftp thread allowed access to eliteforums ftp on these same computers, though it would never allow uploading. It opens up as a webpage rather then a file folder as per the attached image which was accessed by this computer.

I believe it comes down to integrating the address/usename/password all into the same address .. but I dont know how to do it, nor can I find how to.

ftpaccess.JPG - 33kB

Ium - 1-6-2004 at 19:43

The standard method of integrating the username and password into an FTP address goes as follows(removing the "+";):

+ftp://username:password@address

So in your case Axt, you should present the address as follows:

+ftp://axt:******@species8472.dyndns.org

Do you understand?

[Edited on 2-6-2004 by Ium]

Axt - 1-6-2004 at 19:51

SUCCESS!

Thankyou.

axehandle - 1-6-2004 at 20:23

Ah. Should have thought of that. My firewall supports active ftp, so it never crossed my mind...

Just

axehandle - 2-6-2004 at 03:09

did a major configuration overhaul. Please tell me of any troubles.

Organikum - 3-6-2004 at 10:30

I downloaded the file "solid_acid_catalysts.pdf" but it seems to be damaged (or got damaged whilst traveling to mine?). I believe it was from Polverones folder - if somebody could check this please and re-upload it?

The one I downloaded myself is damaged too. I don't recall which files but there are some other pdfs which seem to be damaged too.

axehandle - 3-6-2004 at 12:05

All file systems check out OK. The file(s) must have been damaged before they were uploaded. I've never seen Linux send erroneous network data from a file or, for that matter, have filesystem errors without a faulty disk --- and that would yield a filesystem error rather than silently corrupt data.

The FTP is on a reiserfs filesystem on one of my RAID5 arrays.

Organikum - 3-6-2004 at 14:56

Either here or in a own thread we should report damaged files for deletion and re-uploading. I am sure they got not damaged on the ftp itself though.

agreed?

Polverone - 3-6-2004 at 16:40

The file solid_acid_catalysts was damaged on the CD I was storing it on. There appear to be a few other dodgy files on this CD. I don't know if this is the storage medium itself deteriorating or if they were always bad on this CD. Given the size of the solid_acid_catalysts.pdf and where I retrieved it from, I am pretty sure it's a Chem. Rev. or Industrial and Engineering Chemistry article. I will try to grab it again.

axehandle - 3-6-2004 at 22:22

Good point. How about here?

Esplosivo - 3-6-2004 at 22:56

After a quick search I have found out the following files to be damaged, at least in my case.

' _indx.pdf '
' H2O2-propellant.pdf '
(I think both have been downloaded from Polverone's folder, but I'm not sure)

That's all I found for now. Anyway, I will report any damaged files I'll find.

mess

axehandle - 4-6-2004 at 00:23

The file structure is a mess. I'd like to organize everything logically in a tree structure, but I'm not sure where to start, or how.

Any suggestions?

Files structure

Alchemist - 4-6-2004 at 06:06

Hello Axehandle,

How about folders labled as explosives, precursors, pyrotechnics, weapons, etc..
Then break now each catagory with a separate folder for pdf files, word files, plain text,and etc.

Just a thought!

P.S., is there a way to search?

chemoleo - 4-6-2004 at 06:16

Hmm, I also agree on creating folders based on topics. Not wanting to praise myself, but the structure you can see in the chemoleo directory makes sense to me... thats because I created it of course.
I would put all software into a separate directory, regardless it's use - i.e. chem. programs, databases etc all into a software directory. Ebooks of whatever type (pdf, txt, djvu, doc) in subject categories. I would possibly actually separate proper general ebooks and specific preparations, into subfolders of a given section.

Regardless, the aim is to enable the user to find a specific pdf on a subject as fast as possible. If general ebooks on, say, explosives are separated from the much more numerous specific preaparation pdfs (such as patents, etc) then it should be easier to find what you want. I have attempted to do this in the chemoleo/energetic_chemistry section.

Whether you agree with the latter or not, the FTP definitely has to be ordered against category, however.

PS as to searching, aren't there programs that generate file lists automatically, that basically list the whole directory/file structure in a text file? The idea would be for the user to download this list, and search for himself.

lucky you......

Just a jest. The structure of my files uploaded makes sense to me too! Books are in "books" and patents in "patents". Good - isnt it.... :P

chemoleo - 4-6-2004 at 06:25

Lol I know. It's personal preference really, of course. In the end it's axe's decision :)
Still, I hope you agree on that it needs to be categorised into subject areas. I guess that's what everyone'd want to see...

Organikum - 5-6-2004 at 09:06

Just want to thank axehandle - I finally could download the Kirk-Othmer and I had a real good speed which was obviously more limited by the connection I used than by the ftp - very good!

Praise always works with me.... -- but I still won't marry you, Orgy :). Seriously though, I'm happy it seems to work so flawlessly.

chemoleo - 9-6-2004 at 19:51

Can I just ask (for the lack of another place to ask), what happened to this guy who had this big patent collection in a new thread (which came from http://www.pat2pdf.com/ ), and who also posted in this thread about the file structure?
I am wondering because that collection was well-ordered, and with a LARGE amount of VERY useful information... and now it seems to be gone :(

Edit: I believe that use was tom34 ... but he appears to have deleted his posts...

[Edited on 10-6-2004 by chemoleo]

Corrupted KO ?

pdb - 10-6-2004 at 03:51

I got the Kirk-Othmer image as well, but the file seems corrupted, as, once mounted, it appears not to be accessible.

Has anybody else faced the same problem with this file ?

Organikum - 10-6-2004 at 04:04

You have to burn it on CD (Nero works fine) by using the cuesheet (.cue) and the settings: "disk at once" (not "track at once";) and it will work fine.
Once burned on CD you can install the Kirk-Othmer on your harddisk.
I believe Rhadon told that this version does not support Win-XP, but I am not sure on this.

Patents

Melmoth - 10-6-2004 at 04:36

I upploaded my patent files in the upload folder under "Patents - Melmoth" its all converted to PDF.

S.C. Wack - 10-6-2004 at 09:57

It works on XP, I know. At least from emule as .rar. And I got it to work without transfer to DVD (big file) by extracting or moving it to a different folder. I think I had already associated it with daemon tools by then. It was trial and error, and suddenly the dialog on disc set up started. Not very helpful but I'm not trying to give advice.

But when I deleted what I thought was one of three copies made in this trial/error, well, the file path that dialog was using was unclear for me and I no longer have it. [duh]Check files before emptying recycle bin[/duh] This is no biggie and I've not downloaded it again. I was so pissed I deleted the other copies, too.

This is because this 2001 edition sucks, for our purposes, in general, IMHO. Its reputation comes from earlier versions. Each newer edition sucks more for those without millions to spend. The one in the library, the '78 ed. I find much better, and if you can find earlier ones...

If you can find the earlier ones, keep in mind the weird way they write. In the first part of an article, they make chemistry seem very easy, leaving out many important things like temps, side or in fact major reactions, and pressures. You have to know better and really dig in to an article to get it. And some of their refs are pretty obscure.

Does everyone else disagree with me on this?

EDIT: AHA! Found another copy in the "unzipped" folder, and I have another on DVD. Futzed around...copied the unzipped to a new folder...opened daemon tools...mounted image...and as usual only the .cue file shows up. So- changed the "files of type 'all images' "(default) to 'all files', so now it sees the .bin. Opened the .bin and success!

Not that there is anything wrong with Nero 6.

Amazing ! The hard copy I burnt on CD doesn't work. I tried mounting with daemon from the .cue file without anymore success: I then tried from .bin and it worked !

I've been debating with myself about the different models of directory structures possible to create on the FTP, and after not so careful consideration I've come up with 8 top-level groups:

01_Chemistry
02_Technochemistry
03_Biochemistry
04_Physics
05_Electronics
06_Tools
07_Software
08_Misc

Suggestions?

There should probally be a folder/section for energetics too, alot of what is on there is explosives related.

I have a old book called 'glass working by heat and abrasion' from 1912 by 'Paul N. Hasluck'. It has procedures for making glassware mainly for chemistry apart from cosmetic glassware.
I could scan it in and upload it to the FTP if anyone is interested.

SURE

Alchemist - 21-6-2004 at 11:55

Yes,

Please DO upload it. Saounds very interesting!

Thanks, the Alchemist!

froot - 22-6-2004 at 10:16

Ok it's uploaded.
In the uploads folder called 'glass working.pdf'
If you try some of this I hope you succeed. I find glass blowing very difficult, you need hands more stable than a brain surgeon's. I have 25mm bora-silicate tubes which I played with.
Good luck! ;)

P.S. if there any pages you cannot read please u2u me and I'll organise the for you.

I have already uploaded them in PDF form,
but thanks for the thought!

a_bab - 23-6-2004 at 08:44

froot, thank you for the glass working book, but in the future can you compress the file please ? Rar made it more than 10 times smaller (7 Mb, and the original pdf is over 80 Mb).

By doing this, we gain more ftp space and more time (some members are still on the dial up, you know ?)

Eliteforum - 23-6-2004 at 09:01

http://www.foolabs.com/xpdf/download.html - Offers better compression that .zip files. Up to 40% more compression!

It's also out in linux format.

Another is http://www.7-zip.org/ as a far better compression than Zip.

Test showed the following for 1.79Mb of files.

.zip 871Kb at maximum compression
.7z 520Kb at standard compression

[Edited on 23-6-2004 by Eliteforum]

froot - 23-6-2004 at 11:55

No problem a_bab sorry about that. I'll give it a try and upload it again if you wish, then the uncompressed file can be deleted.

The thought didn't even cross my mind. :o
That would've saved me some uploading time aswell.


glass working.rar done! :cool:

[Edited on 23-6-2004 by froot]

a_bab - 24-6-2004 at 07:37

Very good froot, very good. ;)

I'll crop the images, make them B&W (you scanned them in color, that's why the pdf is so big for 80 pages), and I'll re upload it soon.

froot - 24-6-2004 at 08:01

I actually set the scanner to black and white, after the first attempt where I could see the red backing around the sides.
I then set it to 70 dpi but the scan was unreadable. I found it to be marginally readable at 300 dpi 'print quality' which is probably responsable for the file size. If you still see colour in it I'll have to juggle some more with the settings.

axehandle - 26-6-2004 at 20:01

The_Davster - 6-7-2004 at 19:01

I was able to access the FTP fine today. However the document I downloaded, when I went into it there was an "error reading document", but that may just have been a coincidence.
The file I downloaded yesterday worked fine though.

Eliteforum - 7-7-2004 at 03:46

I'm able to log in now. Maybe it was just an isolated case?

Just wait until he gets back I guess...

Edit - 3 posts above, it's 7 days. He should be back by now. Strange

The news of my death are greatly exaggerated. (I went away for a week, came home for a day and then went away for another week...) :)

My ISP had trouble the day I was home, the net problems are most likely related. It seems to work fine now, though.

Some points

chemoleo - 30-7-2004 at 23:21

Hmm, I have been thinking about this, axe, and I know u mean well, and the ideology behind this is supreme. However, I am beginning to have my doubts.
Don't you think that maybe the idea of anyone in the wide world having FTP access may cause problems beyond them taking away bandwidth? What I mean is that maybe not everyone appreciates having free access to vast amounts of information; instead, some people may feel that certain c***rights are being violated.
Of course, that's the nature of the game. But I do think potential problems are encouraged by giving literally anyone FTP access, particularly members who register solely for this purpose.
I realise it's a fine line to be drawn. But I do think that a number of ill-meaning individuals might be sequestered if a policy was maintained to grant access only to those who at least make a remote effort to contribute.
Of course, there is no chance on earth to weed out everyone of those ill-meaning ones (of which there aren't many for sure). But at least that way it will remove most of them... in the hope that by mere statistics, the chance of trouble is lessened.
As I said, I believe in freedom of information, but unfortunately I also believe this deserves a grain of realism!
Just thought it might be good to express this :)

axehandle - 30-7-2004 at 23:32

Good of you to point it out. I've been far too generous.

The last week there has been a torrent of new members, most with a postcount below 2, that have requested FTP access. Now this could be due to E&W being down, or it could have another reason, but that's unimportant. I've taken the liberty to delete (almost) all new and non-contributive users, because I don't really want pain without any gain.

Contributive members are ofcourse not affected, and non-contributive members should strive to become contributive before reapplying.

Dear Sir,

I agree with your views....but I had asked for ftp access to see the material and add some from my personal collection.

Can u kindly re-activate ftp account...I will complete the activity of downloading some material and later would add some references from my collection

I think this would help in sharing information amonst group...and may fulfill the need of information sharing similar to posts in forums

Regards
K.S.Rao

ksrao, you don't need an account to upload, just download.

ksrao - 31-7-2004 at 09:54

I guess I am not only looking to share but also like to get some material from ftp and to be frank I was in middle of downloading some documents....I spent allmost 2-3 hrs and stuck up downloading hlf of the document.

I request you to kindly grant me an username and password

Eliteforum - 31-7-2004 at 12:44

Offer something in return first! Don't be a leech!

axehandle - 31-7-2004 at 14:32

What's troublesome isn't that people download without uploading; I couldn't care less about that --- but that lots of people sign up as members on this board which I love just for the reason of getting an FTP account without contributing to the general discussion.

So to all deleted users who have begged to get their access reinstated: NO (I'm temped to use profanities here...)

Actually you do need an account to upload, which is good because it prevents data-bombing. It's a two-edged sword though.

It might be a good idea to have just a public upload account. And those that want access tag the end of their upload with their username or whatever.

FTP Upload of Chemical Engineering Textbooks

JohnWW - 31-7-2004 at 21:53

This is to let members know that I have uploaded (on 30 July) to the "upload" folder of the FTP a collection of 14 important chemical engineering e-books (English-language), published from the late 1960s to early 2000s (dates given in the file-names). These are the ones I got through someone called "Pipi" on http://www.todoquimica.net/modules.php . They were scanned, digitized, and converted to PDF files, from print copies believed to be in a university library in Chile. I repacked them in individual ZIP files. Enjoy, use, and distribute them!

At the same time, I also uploaded a number of smaller chemistry and chemical engineering monographs and utilities. There will be many more to follow when I find time; I have several Gb of stuff of interest to members which is not yet on the FTP.

axehandle : Just wondering if you will be having any criteria to decide which newer members you'll give ftp accounts to?

Also, is it possible for you to post a list or something of the content on the ftp at all?

I'm interested in contributing, so I would like to know what sort of content would be wanted, if it is only chemistry or if most science based texts are wanted?

Re: New File Uploaded To FTP: Encyclopedia of Chemical Physics & Physical Chemistry

JohnWW - 2-8-2004 at 23:31

I have just uploaded today to the "upload" folder of the FTP the following new e-book file, which originally came from ftp://books:books@myebooks.dyndns.org :
Encyclopedia of Chemical Physics And Physical Chemistry(retry).pdf , 68.3 Mb.

The exact file size is 71,670,857 bytes.
THis item should be of especial interest to chemical engineers, and researchers in quantum mechanics, spectroscopy, thermodynamics, and statistical mechanics.

I also wish to note that I had to have two tries at uploading it., using WS_FTP 7.5. The first time, my computer crashed out, and the incomplete result (without "(retry)" in its name), of about 40 Mb, is still in the "upload" folder. Axehandle - please delete this incomplete upload. I was unable to resume this incomplete file, as uploaders do not have "delete" permission which is needed in order to resume broken uploads.

This is the second time a crash has happened when uploading - a small utility file which I uploaded on the 30th July is also incomplete, but I am not sure which one.

axehandle - 4-8-2004 at 04:39

Done.

We now have 19GiB of data on the FTP!

Biochemistry Files Uploaded to FTP in Subfolder

JohnWW - 8-8-2004 at 17:03

I have just completed uploading all my biochemistry files to our FTP, about 150 Mb. Because of their large number, I put them in a sub-folder called "Biochemistry&Microbiology(from JohnWW)".

The most valuable item is probably "Biochemistry Garrett and Grisham 2nd ed.pdf", 36 Mb, originally from (very slow)ftp://books:books@myebooks.dyndns.org . With it, I have included tutorial material and study guides made for it by Rutgers University, in New Brunswick, New Jersey, used in their advanced Biochemistry 408 course.

A problem that I have encountered in uploading some large files is that sometimes the upload is interrupted with the message "failed 550", and cannot be resumed because "delete" permission is needed to do so. The following such files had to be completely restarted once, with "(retry)" in the file-name of the repeated upload:

Bioionformatics - Sequence and Genome Analysis.pdf (should be 7.8 Mb)
Biochemistry408SlideShow-RutgersU(PDF-2004).zip (should be 34 Mb)
RNI-MembraneTransport-RNiederman-2002(www_rci_rutgers_edu-~molbio-Courses-MBB_408_512.pdf (should be 1.1 Mb)
In addition, the following file required TWO tries, and only the second, with "(retry_2)" in its file-name, is complete:
(ebook) - Science - Biology Dictionary.zip (should be 18 Mb)

Axehandle - please delete the incomplete attempts of these files.

JohnWW : is ftp://books:books@myebooks.dydns.org openly free to people or is it intended for another group and requires a password and so on?

-H.Porn

JohnWW - 9-8-2004 at 02:18

Yes, it is free for all comers. But it is BLOODY SLOW, now only about 1.2 Kb/sec per connection, allows a maximum of only 3 connections to the same IP address, and is often down (although it is usually on-line from about 10 a.m. to 10 p.m. GMT).

Re: Aspen 10 or 11, anyone?

Does anyone have Aspen 10 or 11, the most comprehensive chemical engineering design and simulation program? If so, please upload it to the FTP. Thanks in advance.

Has anyone uploaded 'The Organic Chem Lab Survival Manual' to the FTP yet?

I remember someone saying that they planned to scan it..?

Dynamically updated file list

axehandle - 19-8-2004 at 00:22

The directory "0 CONTENTS" in the FTP root
from now on contains a listing of all files on the FTP in various compressed formats, updated hourly by a very small shell script. I would do it minutely if not for the very old P-3 CPU in the server (compressing steals my precious cycles).

Only files accessible to all are shown, certain user-specific private directories etcetera are shown as "error opening dir". This is as should be.

Procedures in Experimental Physics, John Strong

HRH_Prince_Charles - 19-8-2004 at 15:07

Hi Folks

I have this book, first printed 1938 - it's has great techniques for the amateur.

I don't want to scan the whole thing, but it does have some good chapters: glass blowing and heat & high temperature.

I couldn't find it on the ftp but will scan and upload if anyone is interested.

Chas

Edit: OK, I've scanned one of the chapters, will finish and upload tomorrow

Ah, rest assured plenty will be interested, particularly in the subjects you mentioned!

axehandle - 20-8-2004 at 13:28

Thinking that I should consolidate the server and my Linux workstation, scavenging the best parts of both and build a super machine with 1GiB of RAM serving both as server and workstation. Yes, this would be good for the electrical bill, and save place.

Don't know why I write it here though... I must be amazingly bored. Blääää.
