Re: Common problems with Ubuntu
Why do you think that MS believe in security by obscurity? I believe that security problems in MS products are generally speaking being released to the wild. Why I think MS products has better chance to be secure than your local Joe Software shop, because they're having strict policies which are supposed to enforce that: 1) The SDL development process, which includes fuzz testing the software specifically against security breaches. Every MS software must undergo that. Do regular software you use do? 2) Cryptography awareness. Every product which uses crypto must be authorized by a specialized crypto group. Crypto is a thing which is easy to create and hard to verify. Is Winzip encryption algorithm being reviewed by crypto expert? I'd rather know that the software I use had a strong peer review.

Plus, even if MS truly changed its colors (and I -really-, -really- doubt it), considerable parts of the Win32/WinNT basic design was never designed with security in mind, and breaking them will force MS to drop backward compatibility with previous releases (such as XP/2K3/etc) - something that MS simply cannot do.

Re: Common problems with Ubuntu
I guess we'll stay divided, but still, for the sake of the completion I want to clarify my argument. My point is, that some security decisions (for example, the Tuesday patch you mentioned), even if they are very wrong (and obviously, MS security guys would beg to differ) doesn't play a very big role in the overall security of your products. However good software engineering practices plays a big role, and MS is doing that big time, and putting a lot of resources for secure software development. So the question whether or not the Tuesday Patch is a good idea, and whether or not full disclosure is a good idea matters much less than the question whether or not they have security expert evaluating the security of each and every software signed by MS. About the complexity of Windows and backwards compatibility, it is indeed an issue which any company which develops for Windows need to handle with. I really don't see how is it related. Keep in mind that MS is making much more software than just the windows OS.

Re: Common problems with Ubuntu
I think you have to make a distinction between older MS software (such as XP) and newer ones (such as 7). For example you defenitely don't run as administrator in Windows 7, and you've got a built-in sudo like system. I, like some people who replied, had bad experience managing Windows machines, and it was usually viruses. However in recent versions I noticed that even at the hands of the inexperienced users, and without any virus scanner, the system stays relatively clean. The point about Windows complexity and background compatability is true and taken. It is against security, and maybe it tips the balance against MS and Windows related products security-wise. The other remark which I highly disagree is that there's no need to convince me. I'm discussing here in order to be convinced, and I'm usually glad when someone enlightens me.

Problems found after the freeze date for a distribution are not fixed until after the distribution. This meant in 9.04 IDE optical drives did not work, ATOM processors did not boot and a lot of minor bugs. The ATOM problem was fixed with the netbook respin, but AFAIK a new boot disk of the regular version was never released. 2. They take about a month after a release to to fix things and then often break them. For example, I have a system where gnome stopped working, and I have tried reinstalling gnome, deleting prefs, etc and it still does not work. It's too involved to reinstall from scratch. 3, They moved things around and are not like any UNIX or Linux based distro. While it's debian based, they forked off a long time ago, and debian packages often won't work, nor will any of the administration things you know. 4. They set things up the way they want them and it's darned near impossible to make them work properly if it is not what they wanted. Ask anyone with a Mac running MacOS 10.5 or 10.6 who wanted to use netatalk. 5. Long term support is a relative term. Fixes that you would think are applied are not carried back. Only the obvious critical ones. 6. Packages are not updated. Many of them are never updated, some are updated daily.

Re: Common problems with Ubuntu
Actually I once have had an Ubuntu at home and it did not give me any trouble. I'm looking for a distribution for my workplace to 4 developers seats with minimal maintainance needs. After we'll install a distribution we're unlikely to change it, so I prefer to ask around for some general impressions. Your example about cars is an excellent example for what I'm seeking. For example, it is a common knowledge (although I'm not sure it is really true), that Japanese cars are very reliable. While French cars has expensive parts, thus has a big maintainance fee. Why is that? Why does the brand name matters? Why won't we look at the fact sheet of each car model? The reason is, that the engineers at a certain company, are likely to have a certain engineering attitude, and thus many models are likely to suffer from similar faults. For example, Microsoft is now known for excellent security review practices. Whichever MS software I choose, I can rest assured that it will be relatively on the high end of security. Moreover, some people in this list wrote things like stay away from Ubuntu, anything but Ubuntu, so I wanted to know what exactly were the problems they've had. Geof's answer is *exactly* what I had in mind when asking the question. An example problem which according to Geof is specific to the Ubuntu *brand* is lack of fixes to a certain bugs even after a long time. That's the brand, not the specific issue. I can't tell that from reading a long list of specific problems with a certain version.

Re: Where to learn Linux?
Well, it depends. State on CLI is not necessarily much more availible. For example, when looking at a vim window, it is not immediately clear whether you're at: (1) vim edit mode, (2) vim regular mode (3) selecting something with screen, where your keyboard are now not even sent to the vim window. I think it's more a matter of training. I'm a trained vim user, so I can see immediately through the subltle hints (cursor shape, etc.) which state am I in. And nevertheless, I find myself many times typing Ctrl+[ to reset the state, since it's faster for me to reset the state, than to figure out whether or not I'm in text mode. OTOH I use at work the windows environment alot. And I found myself launching programs with launchy (no state needed here! In CLI I need to remember where would Ctrl+3 lead me, and whether or not I can exit the programs there. In windows there's no state, all the apps are Alt+Space away. Always), using the Winkey+Number to navigate between programs (again, no state in here, Winkey+3 gives the third app you launched, whereever you are). Keyboard friendly programs also gives me a similar stateless feel. For instance, eclipse has the F12 key to bounce me back to the editor from many states (and all common states), and have Ctrl+3 to search for a specific command. My main problem with GUI interfaces is their relative sluggishness/resource usage. A similar criticism was directed to emacs when computers were slower. I hope Moore's law would be able to handle it eventually. On Mon, Mar 15, 2010 at 9:39 AM, Dov Grobgeld dov.grobg...@gmail.comwrote: I think it there is something more subtle going on, and that is the concept of a state. The state is where you are and I feel the big difference between GUI and command line operation is in the latter, the state is available without heavy visual interaction. Once you have used the system enough, you feel the state, and you build a motoric memory for moving from one state to another. With GUI systems you never reach that proficiency and you have to do more guess work and more hunt and peck to move from state to state. It may be easier the first time to use a GUI, but the second and the third time, you'd be better off typing the command, because it is much more repeatable. So the difference between Unix/Linux and Windows in this sense is that in Unix/Linux you have full control of the system from the command line where you can have this feeling for where you are. Anyhow, this is sliding into something that is quite far off from the original question.

Re: cross-platform bare metal remote restore system?
When my parent's windows machine occasionally became too slow (as most undermaintained windows machine does). I tried to ease the situation like so: I divided the windows into a minimal C:\ partition which contained the windows directory, a d:\ which contained the rest of the data (program files, documents and settings, etc), a hidden parition /dev/hda3 which contained copy of the c:\ partition, and finally a small linux partition. I hacked up a script that would once every X boots up the linux partition that would recover the c:\ partition from the hidden partition. That way, every once in a while the users would feel as if their windows was reinstalled (a known cure for many windows diseases. This didn't work out eventually, since some windows program assumed Program Files is on C:\, without checking the registry, and behaved strangely. I used partimage for this job, and was generally content. I don't recall a single data corruption. Of course this is highly inaccurate estimation, so use with caution.

One of the requiremnets is that the data is only wiped on one of the two disks in the machine, or preferably just a single partition (the OS).

Runtime security/memory checks for gcc/gdb
We have a big legacy embedded code we need to maintain. Often, we wish to run some functions of the code on the PC with injected input, to test them or to test changes we've done to them without loading the code to the device it should run on. The code is written with C. Obviously, this is not an easy task, it is more difficult because, the code is bug ridden, and many times it works by accident (for example, a NULL pointer added a constant and then derefeced, this worked because the memory address was legal). Since the code is big, our strategy is: compile just the parts you need, debug it enough so that it would run on the PC, and keep the changes. Hopefully, after enough time, all (or most) of the code would be runnable on a PC. We use gcc+gdb to compile and debug the code. In Visual Studio's cl.exe there are some security checkshttp://msdn.microsoft.com/en-us/library/aa289171(VS.71).aspxat run time. This can really assist debugging. For example knowing when an unintialized variable was used can save you alot of frustration when trying to figure out why you're getting a wrong numberic results. My questions are: 1) Are there parallel (or better) runtime security checks for gcc/gdb? I found the -fstack-protection stack canary switch, but are there more of this type? 2) What other tools are there which offer similar protection? Valgrind of course is the first thing that comes to my mind, but I'll be glad to hear any more ideas. For example, I would love to be able to get a warning whenever a pointer is dereferenced twice, where the first time the pointer points at the memory address of variable x, and the second time it points to variable y. That way I'll get a warning for the following bug: int x[3] = {1,2,3};int y[3] = {4,5,6}; int *p = x; for (int i=0;i=3;i++,p++) (*p) = (*p)++; // note the = 3) We use win32 for regular development, so if anyone knows what is the support for such tests in cygwin/mingw, I'll be glad to hear about it.

Just because it spews out thousands of warnings does not mean they are not all relevant. Compiler warnings are the easiest to fix, easiest to find, and are often written off for no justifiable reason. It's more complex than that. The code currently work on the embedded device. This is a mission critical device, so we cannot make changes to the runtime code without testing it throughly first. I try therefor to fix the problem in the emulation level without touching the actual code. (for instance, overriding a certain problematic function which used an uninitialized variable, and got away with it in the embedded device, but not in the desktop, or, replace the macro which stores a specific memory address (hex number) which is used by a the code, and is obviously relevant only for the embedded device) Having a good runtime error checks (such as valgrind) will help me with recognizing this anomalities. I'm not sure at which version this started, but gcc 4.4.2 with -Wextra catches your second example (array bounds problem).

I'm not saying that the CLR is a panacea for cross-platform development, but I'm saying it is a viable option. Is C/C++ easy to get cross-platform (hint: dir.h, hint2: take a look at some boost source)? Among the current solutions, it doesn't seems to me like a bad choice. And indeed it does seems better to me than relying on WINE. I used Java a bit for linux+windows projects.

Thanks for the suggestion but we must use our own in-house email sending software which is an integrated part of our website. So mailman and the like doesn't really fit in. We must synchronize it with our database, and mailman's daily-digest options doesn't match our needs (the daily digest is in a different format than just cat'ing all emails sent today and sending them. What we really want to get of our heads is managing another SMTP server.

Tracing the functions stack through gdb
Problem: I wish to hack and solve Bidirectionality related bugs in Lyx. However, I don't want to read all and understand all the code in Lyx, but only the code related to cursor movement, character insertion, etc. How can I find the relevant pieces of code quickly? Suggested Solution: Run Lyx with a debugger, have the debugger print constantly which functions from lyx sources (so that printf() wouldn't litter the output) are being called, now press left, and watch the execution flow, based on that locate the required code. Is there any way to do that with gdb?

Re: [Job] MySQL consultation
This is not the problem. The problem is that running Queries like: SELECT SQL_CALC_FOUND_ROWS c.cat_ID FROM posts AS l,post2cat AS a2c, categories AS c WHERE (date2006-01-01 AND date2006-01-02) AND(c.cat_ID=a2c.category_id AND l.article_id=a2c.post_id) AND (c.category_name=cat1 OR category_name=cat2) GROUP BY l.id HAVING count(a2c.rel_id)=%s LIMIT 10; Takes about 10 minutes to complete. I want to run many such queries, and I'm not sure if I can optimize it, or that since the DB is huge, I've met the SQL limit and I should start looking in other directions (reducing logs resolution etc.). Will the fact I'll have no TEXT columns speed things up? Will removing all columns except of id from the giant posts table throttle things up significantly?

immitating Magiccard with linux.
There's a PCI card called Magiccard[1] which is recoverring one of your harddrive's partitions after each period of time or manually. The main use of that is to back up a windows partition, and make ruining it impossible. I'd like to immitate it on software. My plan is to divide the harddrives into three partitions windows, backup and linux, on the MBR we'll install Lilo,grub or such First we'd make a backup of windows to backup using, say, partimage. Now, when loading the linux you'll be fronted with an option to restore backup or to update backup. The problem is dates. I'm not aware of any way to cause a LILO or grub choosing an OS using some condition (IE date, a file's content in a partition). Also I'm not aware of any way to load windows after linux is loaded. I think I can handle patching grub or lilo to do as I command, if someone would give me a brief pointers. I'll release this mini-project to the public if it'll be of managable form.
