Learning a second language is certainly much easier than a first one, although I would say you should start to learn programming and not a specific language, but that's a more philosophical discussion. Starting with Python is certainly better than starting with Perl from an educational point of view. Unless you have a specific need to learn both and/or to use Perl, I do not see a good reason to take the effort to learn Perl at this moment as a second language, as they are in the same league. If you want to extend your programming skills beyond Python, I would suggest to start learning C, and maybe even Javascript. The latter not because it is a nice language, it is not (although it inherits many things from Python and Perl), but because it has quite some practical value in the current era of web and even mobile app development. But again, all opinions are just mine and YMMV ;-). -- --Jos Vos <j...@xos.nl> --X/OS Experts in Open Systems BV | Office: +31 20 6938364 --Amsterdam, The Netherlands| Mobile: +31 6 26216181

There are IMHO many reasons for that, some are subjective, some are objective. My personal prediction is that the use of Perl will decrease during the time and that Perl 6 will never gain a significant "market share" in programming land. I think even part of the Perl community "fears" the same. See also the TIOBE index (http://www.tiobe.com/tiobe-index/) although do not consider this table to be a reflection of good taste ;-). And go for Python 3. Although Python 2 and 3 are almost compatible (which Perl 5 and 6 are definitely not, which is part of the problem), when starting to learn better stay with Python 3 from the beginning. Because you asked: I've been programming for 30+ years (and using UNIX for the same amount of time) and have used a large number of languages (of course including Perl). Python has become my favorite language, although for some things I have to switch to C or even JS.

Not specifically meant as an answer to you, but as a comment in general: Some open source people (a community I consider myself part of, but not in this sense) tend to act like communists and look at companies acting in the open source world in a suspicious way (this word has already been used in this thread), some maybe even think capitalism is bad in general. Well, some companies indeed are evil and try to hijack and/or abuse open source software and its community. But in general, remember that today's major open source projects couldn't live without the support from (commercial) companies, where Red Hat is even one of the main players. And until now RH has proven to play the game pretty well. Without Red Hat there was not Fedora, no RHEL, no CentOS (also not in the previous incarnation) and no SL. It's understandable that people around the CentOS community look at the RH/CentOS case in a critical way: I also did that myself. But we have to live with the situation and it's not that bad now.

Every action by any company -- literally every single action, ever -- is motivated by that goal. This sounds as if this is bad: are you a communist? The world runs because companies exist, trying to make money. I even dare to say the open source world in its current form does only exist because companies like Red Hat and many others contribute a lot of work. So, we should not attack them, but support them. In general, yes, companies exist for making money. The way you talk about it (literally every single action, ever) makes the statement IMHO formally not true, but in general, yes, money is their motivation. The question you should be asking is: How does Red Hat believe this move is going to make them money? Those were statements of fact. What follows is merely my opinion. The best way of debating is saying your statements are facts, yes, but that does not make them real facts. Right now, anybody can easily get for free the same thing Red Hat sells, and their #1 competitor is taking their products, augmenting them, and reselling them. If you think Red Hat perceives this as being in their financial interest, I think you are out of your mind. As someone else already pointed out: no, you do not get the same thing Red Hat sells. But for some people it may be ok for what they need. And there are other ways to look at it: the fact that clones like CentOS are used a lot is an indirect advertisement for the quality of Red Hat. The fact that there is (AFAIK) no SLES/SLED rebuild does not help the SUSE brand at all. So, there are also arguments against your theory. SRPMs will go away and be replaced by an ever-moving git tree. Red Hat will make it as hard as legally possible to rebuild their commercial releases. The primary target of this move is Oracle, but Scientific Linux will be collateral damage. I consider all of this pretty obvious, but perhaps I am wrong. I hope I am. It is not obvious. Instead, it is a very, very unlikely scenario. But I might be wrong. I hope I'm not. P.S. There are a lot of companies abusing the open source paradigm, stating their product is open source, providing just a tag-less git repository, no documentation, etc. and just selling their product for money as open source (which is in fact the only workable choice you have). Talking bad about those companies is ok for me too, but don't judge too early... -- --Jos Vos j...@xos.nl --X/OS Experts in Open Systems BV | Phone: +31 20 6938364 --Amsterdam, The Netherlands| Fax: +31 20 6948204
Re: NFTables To Replace iptables In the Linux Kernel
On Mon, Oct 21, 2013 at 08:34:58AM -0700, Yasha Karant wrote: [...] -- the actual name of TUV, that evidently is taboo on this list, [...] Evidently? It's complete nonsense to NOT use the name of TUV here or at whatever place, as long as you don't say things about SL in relation to TUV and/or their products that are illegal. I thought only the CentOS community was (for no good reason) paranoid. In the time I created and released X/OS Linux, being also rebuild of the Red Hat Enterprise Linux 3/4/5 sources, I did mention Red Hat, RHEL, etc., but only as far as appropriate and allowed of course. Nonetheless, once a major change (e.g., NFTables replacing iptables) is done in the base source, the production enterprise version must reflect the change -- and in less than a decade. Why less than a decade? Unless there is a fully backward compatible set of APIs, new applications and revisions typically use the current not historical APIs. Presumably, there will be NFTables features that application developers will use that have no iptables backport. Thus -- how long is the delay? Typically, are two major releases (e.g., NFTables in EL8) the usual delay? Does anyone have historical data from EL/TUV? Fedora 20 seems to use the 3.11 kernel, so it won't have a kernel with NFTables. RHEL 7 is already being developed (and in alpha stage as far as I've heard) and will most likely have a kernel = 3.11, so this makes the statement that EL7 probably won't either very trustworthy. There are no statistics about delays etc. needed to just see that RHEL 7 won't use a kernel that supports NFTables. So, there is no artificial delay created by RH to postpone things in RHEL, it's just common sense when someone says this about NFTables in relattion to RHEL 7. -- --Jos Vos j...@xos.nl --X/OS Experts in Open Systems BV | Phone: +31 20 6938364 --Amsterdam, The Netherlands| Fax: +31 20 6948204
