[mailing list] lost messages, squeakfoundation gone
by Martin Drautzburg 01 Apr '02

01 Apr '02

I occasionally notice that my postings get lost. This may or may not coincide with situations where http://lists.squeakfoundation.org/pipermail/squeak-dev/ is dead and squeakfoundation disappears from DNS. What do you think ? nslookup basically works: > sunsite.unc.edu Server: data.addcom.de Address: 62.96.128.66 Non-authoritative answer: Name: helios.metalab.unc.edu Address: 152.2.210.81 Aliases: sunsite.unc.edu Can also find org: > org Server: data.addcom.de Address: 62.96.128.66 Name: org but not squakfoundation.org: > squeakfoundation.org Server: data.addcom.de Address: 62.96.128.66 *** data.addcom.de can't find squeakfoundation.org: No response from server Trying another nameserver > squeakfoundation.org Server: ns.surfeu.de Address: 212.197.144.34 *** ns.surfeu.de can't find squeakfoundation.org: No response from server

Squeak for everyday use??
by Mayuresh Kathe 01 Apr '02

01 Apr '02

Hi, Lets suppose, I want to use Squeak on a regular basis for the following tasks, how could I possibly go around achieving my goals? 1. Web surfing (not too heavy, mostly googling around) 2. EMails (lots of them, filtering, PGP would be great ;) [handling around 300 mails a day] 3. Telnet (thats one of the most important things in my life :) [is there SSH available too??] <grin> 4. Document preparation (usually LaTeX, would like some way to view .ps files) 5. Journal keeping (pure text, almost 8 years of data, need some encryption technique, certainly wouldn't want my to-be wife to read _some_ of those entries ;) 6. A bit of music (mostly MP3) 7. A bit of drawing (mostly rough concept drawings done while on the move) 8. PIM (Schedules, AddressBook) ~Mayuresh

RE: Apple hyping java...

Guys, It doesn't suck enough to make a difference, and too many times people have declared that "thus-and-such-sucks" for that simple assertion to convince anyone. Remember, people aren't comparing Java to Squeak (or ML, or Haskell) -- they're comparing it to C++. In that comparison, Java looks pretty good. If you want to convince someone, you have got to put a little more work into your argument, and think a bit about your audience. Just for example -- I wouldn't write a compiler in Squeak. I might write a game, or a web server, or a graphical app, in Squeak. From what I see of the discussions of threads and security on this list, I am not at all sure that I would use Squeak in a context where I really needed lots of threads running well, or someplace where I had to worry about someone finding a way in through some hole; the discussions have just not been very confidence-inspiring. That's just my advice, worth at least what you paid for it. I downloaded Squeak once and played with it, and thought it was very interesting, but could never figure out where to begin. I don't have enough free time for this sort of unguided adventure, and I don't think I differ much from most people (except that I probably pick up languages faster than your average bear, and I actually think it would be good for me to learn Squeak). So, to get to the point, you should either quit whinging about how much Java sucks and how misguided Apple is, or you should do something about it. And YOU should do something about it; I also want to become more proficient in ML and Haskell, and I will pursue whichever learning curve is gentlest. yours, grumpily, David Chase (who usually just reads this list)

Basically, #lighter and #darker will now adjust by the same amount, no matter what shade you start from (similar to what #dansDarker attempted). This makes the #raised/inset bevelling of buttons/etc look a lot better. Also tweaks a few users of these methods in the system to adjust for the change. Mostly everything looks fine as is.

Squeak on framebuffer?

31 Mar '02

Hi, Does anyone have an idea about how to get Squeak running on raw framebuffer? That way we can really do away with the (sic) X Windowing System... ~Mayuresh

Squeak in schools...
by Mayuresh Kathe 31 Mar '02

31 Mar '02

Hi all, Over the past week or so, I have harassed the list with my constant ranting about the requirement for a small fast system. The reason being that, I am trying to experiment with Squeak in schools. The mode of deployment will be making it run atop the Linux kernel on framebuffer and putting them on a Solid-state machine. I am also looking around for decent data about how to go about presenting Squeak to students/non-programmers/new-programmers. Eagerly awaiting your replies. ~Mayuresh
