Yes, I did too. I don't think it has anything to do with the number of
posts you make; it'll be to do with the number that get sent to you,
and it looks like it may be something to do with gmail. I tossed an
email to the list-owner address and it's being looked into; you'll
probably need to mark your address as active again. (In case you
haven't yet done that, I'm doing something I almost never do and
including the OP in the To: list. Please don't take this as a
precedent; normally, just reply to the list and let the sender get a
copy through that.)

This sounds like a variation of a classic phishing scam. You get an
email which looks official, telling you that some account you have has
been suspended because you need to verify some information. The wording
of the message is always vague about exactly what account this is.

Don't click on any of the links. At best, they're harvesting email
addresses. At worst, they're harvesting personal information which can
be used for identity theft, credit card fraud, or all sorts of
malfeasance.

Here's some recent examples from my junk mailbox:

I'm wondering if it has anything to do with spam filtering.

If you're using a spam filter (it might be offered as a feature by your
ISP) that bounces instead of just deleting, and the spam looks like it
comes from or through the list, then the list would receive those
bounces without you being aware of it.

I can confirm that your account has been suspended because bounces. That
is: as a moderator, I can view your record in the interface and see that
it has been tagged as such. I can't tell you any more, I'm afraid; I've
just emailed the other list owners to see if someone has a handle on why
this has happened to a number of @gmail.com users today.

I agree in general, but I happen to be pretty familiar with Mailman
alerts, and this one was genuine. Also, it pointed to what does appear
to be the right address (mail.python.org). There's definitely
something going around that's causing problems for gmail users; maybe
spam is getting bounced/rejected instead of being dropped?

I hadn't read your post when I typed up my own. You said everything I
was saying about spam, only better and sooner. :)

I did too. It seems to me that Gmail's spam filter might have been overly
enthusiastic, but the only way to find out is to look at the bounces
that the list
software received.

Yesterday I also received a warning from the debian-laptop mailing list program.

It happended to me too. And I'm a Yahoo user. I clicked the MailMan
confirmation link and all emails seems to be received now (comparing
to what's on the NNTP group).

As others have said this is no longer python related & i am not going to

With yum you get whatever yum is carrying. If you build from source,
you're on your own. You chose to build from source. Now you're on your
own. Have fun. Get to know what it takes to run your own system,
without the package manager's help (or rather, without as much of the
package manager's help). These are Linux system administration
questions, NOT Python questions.

Posted by E.D.G. on November 14, 2013

In view of the fact that I mentioned the following project in both
Perl and Python Newsgroup notes and did not get any hostile responses I am
going to take a chance and mention it again in all three of these
Newsgroups. People posting responses might want to do that in just one
Newsgroup. I will check all three for responses for a few weeks.


This is the Web address for an interesting and apparently unique
computer program written using FORTRAN 77. As far as I am aware, it has
never been translated to newer language. There is a BASIC version that was
apparently written around the same time as the FORTRAN version.

http://www.bfo.geophys.uni-stuttgart.de/etgtab.html

What a number of us would like to do is obtain a copy of the program
that is written in a newer language so that we can then merge it with the
programs available through the following Web page. The new programs would
then be made available as freeware programs to researchers around the world.
This indirect link is being used in an effort to keep Web site related spam
to a minimum. I don't collect credits by having people visit that
(indirect) Web site.

http://www.freewebs.com/eq-forecasting/RH.html

If there are any programmers who might be interested in such a
translation effort then I would be interested in hearing from them.

Etgtab generates Solid Earth Tide and ocean tide data for any
location on or inside the planet. I am not aware of any other freeware
program that can do that.

SunGP available at that second Web site is the only freeware program
that I know about that generates what are sometimes referred to as subsolar
and sublunar types of data. The download code was written using True BASIC.

If you draw a line between the centers of the sun and the Earth then
the place where that line crosses the surface of the Earth is the subsolar
location. The sublunar location is the same type of thing. The SunGP
program code is also available in Perl code, but not through any Web sites.

If this old program is to be translated or reused, do use this
opportunity to fix some bugs in the program.

The data file contains data for 1200 waves, but the program computes
results for 1212 waves. For waves 1201 to 1212, the program ends up
calculating results based on uninitialized data. Whether or not this
affects the validity of the final output results is something that
someone knowledgeable about the field of application has to judge.

Can you just call write twice? e.g.:

f.write(U[i,:,:])
f.write(V[i,:,:])

Thank you,
But it wont allow to write it in unformatted way so
that the fortran code can read

with

open(11,file="input.bin")
read(11) IWI,JWI,XFIN,YFIN,DXIN,DYIN,NREC,WDAY

That is not the main issue. The python write only works with bytes or
strings, not with floats or ints. So you will have to convert your
numbers using struct. So the question is if you know the byte layout
fortran uses and if you can replicate it with the struct module.

which version of python?
if V3.X then you need print ('Hello World')
as print has changed from a statement to a function.

Several people have reported Mailman messages notifying them of their
subscription being suspended because of bounces.

The notifications are pukka and appear to have resulted from a reaction
by Google's mail servers to messages via this list from an invalid
address at a valid domain.

The Mailman admins have implemented a workaround and have attempted to
reactivate all gmail accounts. Please check your susbcription per the
notification email. If you have any problems, drop a line to
python-list-owner@python.org.

Whew, thank you for your hard work.
I was really worried I would stop getting emails about Islam, Hacking

Kidding, kidding. Great job with the fast workaround!

PyPy profiles your code as it runs and creates, using a
just-in-time compiler, highly optimized versions of frequently
run sections. You don't have to declare types or even think about
it; The scheme will work best with code that runs for a
significant amount of time.

cython allows you to declare types, and attempts to create more
efficient code *at compile time* using those type declaration.

Which approach will be better depends on how the code runs and
how clever you are at using cython.

PyPy isn't designed to speed up programs that run for a few
hundred milliseconds and then complete, though it might sometimes
work for that.

Possibly. However as long as you're using basic system libraries and
not higher-level stuff like GTK etc., you can compile on an older
version of Linux (say, Red Hat EL 5 or so) and the result will run
without any problems on pretty much any distribution, even the newest
ones: Red Hat, Ubuntu, Debian, Suse, etc. etc. We do this regularly,
for production code we ship to customers. About the only "basic"
libraries that cause problems are libssl/libcrypto... the openssl folks
just don't seem to care much about this issue.

Yes, I'm aware. Very frustrating. We have a large set of specialized
macros, both in native GDB and in Python using GDB's extension, that are
invaluable for debugging our code. I'm not thrilled about the idea of
trying to get all that working in lldb as well. So we're going to stick
with GDB, building it ourselves, until it no longer works at all. At
that point we'll decide how to proceed.

By relocatable I mean "runnable from any location"; i.e., not fixed. I
have a wrapper around the Python executable that can compute the correct
root directory and set any environment variables or add flags or
whatever might be needed.

Basically I have a large number of test systems and a set of test suites
that are all written in Python, and I need to be able to distribute the
same version of Python plus a specific set of additional modules across
all those systems to be sure they all have the same environment. Plus
the set of systems changes (new systems added/old ones removed)
regularly. I'm handling this by checking in the Python distribution
plus modules into a "tools" Git repository, then cloning it on each
system. However, I have no special privileges on these systems (so I
can't modify any system locations such as /usr/local) and I can't
control what user account will be running the tests (so the user's home
directory, where the tools repository is cloned, is not constant across
the systems).

I have this working on Linux with very little effort. Now I'm trying to
get the same result on MacOSX.

I am implementing an authentication system(in Django) using LDAP as the
backend(django-auth-ldap). When we fetch the data from the LDAP server for
a particular valid user, the data associated with the user contains the
thumbnail photo in hex representation. E.x.:

[('CN=XX,OU=Users,OU=Accounts,DC=test,DC=com', {'msExchBlockedSendersHash':
['\xce'], 'mailNickname': ['test_user'], 'primaryGroupID': ['513'],
'logonCount': ['1021'], *thumbnailPhoto:
['\xef\xd8\xff\xe0\x00\x10JFIF\x00\x01\x01\x01\x00`\x00`\x00\x00\xff\xdb\x00C\x00\x08\x06\x06\x07\x06\x05\x08\x07\x07\x07\t\t\x08\n\x0c\x14\r\x0c.....']*......
]

How do I convert the hex data for an image to the actual image?

Any help would be greatly appreciated.


Thanks,
Shyam

Well, the first few bytes suggest that it's a JPEG, so save the bytes as
"something.jpg" and there you have it: an actual image.

Alternatively, you could load it into PIL [1] / Pillow [2] and
manipulate it as you see fit...

"list"? As you have already noted, the mailing list is bi-directionally
gatewayed to a usenet group. The advantage of usenet is that anyone can
read or post without having to sign up. That's also its disadvantage.

I've downloaded ogg2mp3.py (http://emptybits.com/ogg2mp3/ogg2mp3)
by Darren Stone http://bitmason.com, I've compared two
conversions.

Thus far, the perl utility produces a clearer playback, but I have
not yet played with the options available from the python script.

Both scripts rely on oggdec, ogginfo and lame.
On the mac available through macports, available on other *nixes as
well.

If anyone is interested, I'd welcome feedback on the python script
above and I will fiddle with it (not being an audio expert) to see
if I can get the playback improved.

I've looked at pymedia also. Have not tested it.

FYI.cheers

I do wish that people would stop apologising for poor English, it's an
extremely difficult language. IIRC there are eight different ways of
pronouncing the vowel combination au. Whatever happened to "There
should be one-- and preferably only one --obvious way to do it."? :)
