I also had the very same feeling the first times I used the "recover lost changes" option. Now that I gained experience, I live comfortably with it.

actually, to tell the truth I figured out how to get most of my methods back. But not the right versions. I wonder if I can back out the changes and try to select the ones that I do need, but there are soo many. It does throw an error when I select multiple changesets. When I use the "remove do it" that helps the most. its just such a mess right now On Wed, Feb 17, 2010 at 11:23 PM, Alexandre Bergel <alexandre(a)bergel.eu>wrote: > Hi Nathan, > > > Is there any way to do a recovery besides the Recover Lost Changes > > option that doesn't seem to work? > > What do you mean by "doesn't seem to work"?

[Pharo-project] So your working on a cool project and Pharo crashes

by Nathan Tuttle

Is there any way to do a recovery besides the Recover Lost Changes option that doesn't seem to work? It seems the change log that was left behind has some promising things in it. This is just such a bummer. Lot of good work lost.

Re: [Pharo-project] databases

by Chris Muller

Hi GÃ¶ran, since this is at least the second time you've indicated having a performance issue with Magma, I'd like to reiterate my offer of assistance. I know it takes time to evaluate other persistence options, so I would be surprised if you've already started off in another direction merely because you thought nothing could be done. Indeed, and you even indicated optimism that the slowness can probably be fixed. Given my limited knowledge of Gjaller, it seems to me that Magma should be a perfect fit for it, especially in terms of performance and scalability. My own curiousity is brimming, you are having a performance issue, there are many many opportunities for optimization, wouldn't you like to talk about it? - Chris 2010/2/17 GÃ¶ran Krampe <goran(a)krampe.se>: > Hi! > > Since object databases and other databases are a dear subject to me I > must reply with some "hints" :) > > laurent laffont wrote: >> Hi, >> >> I would like to learn on Pharo + databases.

[Pharo-project] Polymorph: Window with title

by Torsten Bergmann

Hi Gary, there is a difference here, first one displays the title while the second one not: window := SystemWindow labelled: 'Foo'. window openInWorld vs. window := StandardWindow labelled: 'Foo'. window openInWorld An explicit #title: call is required here.

I changed the NetNameResolver in the image, AND I changed OS X's settings. I believe that it didn't work without also changing OS X. FWIW, I worked on a project last year that used Erlang, and it had the same problem on OS X. I know IPv6 is supposed to be the "new standard" and all, but it sure seems to cause more problems when its on than off :). > Maybe unrelated, some months ago, my wife's macbook caused my linux > laptop to disconnect every time she connected to the wireless network. > We had any idea but after a while we noticed that even if I had a > perfect working connection after she connected my connection crashed. > I had to disconnect, she connected, and then after she had a connection > I connected. > > After some research I found that OS X had a setting in the airport > configuration about ipv6.

I was testing Cassandra for storage for a demo app, but I left that on the side. Nevertheless, the code worked correctly in storing and retrieving data from Cassandra.

All those interesting pieces of information about what works and what does not is very valuable.

Well, if this is an important aspect I would look at CouchDB or MongoDB (but so far there is no working driver for Pharo/Squeak - but Kent Beck is working on one, and I wanted to do it - but haven't had the time). These new "document databases" like CouchDB and MongoDB are quite object database-ish, and they work perfectly fine in a mixed environment and have very good Ruby/Python support. For CouchDB we have two drivers at this point, one based on Curl and one using straight SocketStream directly that Igor works on. > - I want to try MySQL too. > Is there up to date small applications on squeaksource which show this > stuff quite well ? Not sure. SqueakSave was mentioned and I think it probably is a very interesting GLORP alternative. regards, GÃ¶ran
