The best way of generating a good representation for an array with header?
Yes, we’re actually viewing the struct at an offset.
So basically it’s a struct like this:
typedef struct {
uint32_t size;
uint32_t capacity;
int array[0];
} Foo;
The whole thing is malloc:ed with extra bytes at the end, and capacity is set to that same number of extra bytes.
What’s then passed around is actually the int pointer at an offset: &(foo->array)
Using the that pointer

The best way of generating a good representation for an array with header?
The advantages:
1. A pointer to the struct offset can be converted to a pointer without any cost.
2. A nullpointer to a stretchy buffer can be treated as a zero length array. Consequently no actual struct allocation is needed to represent a zero length array.
3. A reference to the array is the same size as to a pointer.
4. It can be converted to and back from an pointer without losing any

Using "opaque pointers" right now?
I was looking at the talk from 2015 about opaque pointers.
Aside from using the new methods (e.g. LLVMBuildGEP2), is there any other way to perpare for this change?
And also - is it possible to use something like opaque pointers (that is using a single pointer type) even before the switch has been flipped in LLVM?

Yeah, that’s no problem - the type is needed for signed/unsigned integer distinctions anyway. There’s no getting around having one’s own type hierarchy.

Testing basic direct x capability
Hi,
I am running wine 0.9.58 and having problems running Counter Strike:
Source, Rainbow Six 3: Raven Shield.
I think this is caused by the direct x layer in wine.
My system runs opengl programs fine using the ATI driver (Radeon 3850).
Is there any way I can test directx functionality without having to
download a game?
Dxdiag.exe is not included in wine.
Best regards,
Chris

[PATCH] MAINTAINERS: separate section for s390 virtio drivers
The s390-specific virtio drivers have probably more to do with virtio
than with kvm today; let's move them out into a separate section to
reflect this and to be able to add relevant mailing lists.

hard_breaks
Dear Dressers of RedCloth,
I have a question:
text = "Foo\nBar\n\nBaz"
RedCloth.new(text, [ :hard_breaks ]).to_html
# => "<p>Foo<br />Bar<br />\nBaz</p>"
Shouldn''t that really be "<p>Foo<br />Bar</p><p>Baz</p>"?
So long,

Limited number of phy disks?
In my experiments with setting up a NAS as a VM, I can only successfully
import three drives; the root drive, the cd and one more. However, I have
plenty that I want to use:
disk=[''file:/vserver/vm_disks/Patch.disk.xm,hda,w'',
''phy:/dev/sda,ioemu:hdd,w'', ''phy:/dev/sdb,ioemu:hde,w'',
''phy:sdc,ioemu:hdf,w'',

Fitting compartmental model with nls and lsoda?
Dear Colleagues,
Our group is also working on implementing the use of R for pharmacokinetic compartmental analysis. Perhaps I have missed something, but

Samba 3.0.5 cannot mount Windows 2003 shares
I'm having a real hair-raising problem here and I thought maybe someone
could help. At least I hope so.
My workstation was running 3.0.2a, upgraded to 3.0.5. After upgrading
to 3.0.5, I can no longer mount shares on my 2003 server. This started
happening on an upgrade to 3.0.4 as well, I might add.
Permissions-wise: I own the directory mounts on the local Linux
workstation,

Mail rescue from Dovecot Server
Hi all,
I have a mail folder from Dovecot server. Screenshot:
https://i.stack.imgur.com/11NHs.jpg
Is there any way to import to Outlook, or otherwise convert to readable
format?
I could setup Dovecot on my own server if there is any point.

2 bugs when parsing emphasized or bold text
I''ve found 2 bugs that produce (imho) incorrect rendering results:
1) The regexp for strong (*) and bold (**) is greedy, which produces
very strange results.
The simplest way to show the problem is to give an example.
This is the original code:
=====
Strong:
Lets do a little test *t*
this should not be strong *u*.
Bold:
Lets do another test **t**
this should not be bold **u**.

Creating a vector of categories
Hi,
I have a column in a data frame looking something like:
$sex $language $count
male english 0
male english 0
female english 32
male spanish 154
female english 11
female norweigan 7
and so on.
What I want to do is to order these in to categories, for instance one
category where count>=0 & count<10 and so on..
I want my data to turn out looking something like:
