In response to: Finding files that have not been added to ClearCase

davidnewcomb [Member]

I think the trouble was that it wasn’t “constructive criticism", was it? While I will accept that he raise some points that were important to him he did just slam my article and then blab on about respect.
In response to his points in a well connected office where the source code is not distributed it is fine, tags are called labels in Clearcase and I’m pretty sure you can delete and re-add files!
For all the things I want Clearcase is the best source controller. I didn’t mention anything about the world, only my opinion, which makes me perfectly suited for blogging ;p

David, if you can’t take some constructive criticism perhaps you shouldn’t be blogging. With that being said, it appears Craig has some valid points that can not be denied. In today’s environment of remote office, I also feel it a huge compromise when you are unable to use a VPN. Tagging of course speaks volumes and the administrative component is a nightmare. I can see your points on why you don’t like Git but to paint the whole canvas white because you like that color is wrong. There are other colors to paint with and you shouldn’t slam a contributor with such gestapo zeal. After this kind of response, I too have lost all respect for you.

In response to: Setting up company wide group calendars in Google Apps

Brad [Visitor]

I agree with @Jason & @Ellis that this is ridiculous. Two and a half years later and Google still hasn’t fixed this and they still have the same misleading message that says, “Share this calendar with everyone in your company” and it still doesn’t do the thing everyone assumes it will do.

Just goes to show you how poorly Google products are managed and run. Features that work are great but good luck getting anyone at Google to change something that clearly doesn’t. Falls on deaf ears and empty inboxes.

Thanks for your post here David. Very helpful, though super painful to do every time we onboard a new employee. Google, are you listening?

In response to: Finding files that have not been added to ClearCase

davidnewcomb [Member]

Well I’m sorry you feel that way Craig. For someone who is still green from university in his second job I don’t think your argument is valid or reasonably constructed.

Like a pestilent child you are jumping on the band wagon of git is the best and all the others are the worst.
I’ve used most of the source controllers back to CVS and administered most of them too.

While Git certainly has it’s uses on disconnected systems, in a corporate lan connected project it falls short in my opinion. Just a few points that are worth mentioning that make Clearcase better than Git:

1) Git has to have an entire copy of the source code repository on your local drive. When your hard drive fails you lose everything.
2) Git doesn’t support winking (look it up).
3) Changes from other developers are immediately available in your view.
4) Clearcase’s branch management (and merging) is second to none. Having different branches following each other while diverging. The graphical tools that are available are amazing and allow you to see each version on it’s branch with merge lines. Still haven’t come across anything as useful in other source controllers.
5) SVN/Git/etc makes you have to deal with revision numbers, long strings of similar numbers. You need to be aware of these in order to merge.
6) A single config spec can define what the whole view of the source controller looks like. e.g. /path/dir1 = latest on branch1, /path/to/dir2 = tree with label, path/to/dir2 = latest on this branch but if it doesn’t exist then latest in this branch or what ever is checkout. To to this in SVN/.. you must export then in situ and it’s not easy to change as you see fit.

I could go on but I’m bored now. This is my blog, on my server and sourceforge is full of my projects, so before you start RANTING about respect perhaps you could ask yourself what *you* have done to help the cause?

In response to: Finding files that have not been added to ClearCase

Craig Kopinski [Visitor]

This is stupid. In no world is clearcase the best source control tool. It is obviously the worst. You can’t use it over VPN, you can’t delete and re-add files, delivering activities separate from one another can be impossible at times, there’s no use of tags, you need an entire admin team to manage it, etc……. I can’t think of a SINGLE REASON that it is better than a subversion or git.

I refuse to accept your premise and lose all respect for you. Good day.

You’ll just have to read your path variable and see why it’s not including the correct path. Run each command (from 10) line by line to find the error.

extended the volume to 10x the initial size (which was 4Go) making it 40 Go and not extended the volume up to 10 Go as explained in your article… but the command is the same to reduce the volume so… no problem after all :p

If it’s just a mail server, why don’t I just use Sendmail? Or Qmail? From the description, what makes this project worth switching over to? Nothing!

I once worked at 1&1 and I can tell you its full of nothing but temp agents who never even heard of webhosting until a few months prior when they started working there. Good luck resolving anything with them, especially billing issues. I use their hosting because its one of the most straight forward easy to use shared hosting control panels however I do have hosting at a variety of other companies. If I didn’t know what I was doing there is no way I would hosting with them because on top of the cebu tech support not listening to what you’re asking, you’re generally talking to people who are just as if not less knowledgeable as you are on the more basic topics so you’re not going to get far anyways.

In response to: Configuring a permanant DHCP reservation on a Cisco ASA/PIX

Hellbent [Visitor]

This doesn’t actually work. At least not in MY environment. I added a static arp for host A after it had pulled a DHCP address. Then shut that host off and rebooted the ASA. with the ASA back up i turned host a back on and yes, it did pull the address again but it’s the first address in the pool. this is standard behavior. I repeated the test but instead of turning host A on first after the ASA was up, i turned a second host B on. When it asked for DHCP, the ASA, having an empty dhcp binding table, tried to assign the First address in the pool, the one I had intended for host A. So the ASA tries to give out host A’s address to host B and it never actually gets to host b because the static ARP entry for that address is for host A’s MAC address.
This is something i’ve been bugging Cisco about for YEARS now and they still haven’t added full reservation functionality to the ASA platforms.

All error messages stem from the “exception: java.lang.Exception: Path to JOD Library folder does not exist".

Your “JOD Path” is relative. The trouble with relative paths is that it’s often difficult to work out where you are relative to!
Change the JOD Path to an absolute path and you should be fine.
