So I love OO and have started using it as my primary office suite at home. But it still falls short when it comes to rendering and printing docs and having them look the same as in MS Office.
It's not a huge issue I guess, but it's certainly the reason that I still need to have MS Office installed in a VM. Highly over the top but a necessary step until OO can render stuff faithfully. My wife, for one, will not switch until it displays word docs correctly.
Is this just me having this problem as I never see other people complaining about it.
Ok my own post spurred my curiosity again and I clicked the link a few posts up. http://www.stellafane.com/atm/atm_myths.htm
* How do two Flat Pieces of Glass grind into Spheres?
With the Mirror on top, the tool on the bottom, and coarse grit in between, we start grinding with the mirror overhanging the tool. We rub the center of mirror against the edge of the tool, and this wears a depression in the center of the mirror (the edge of the tool wears down also, so that the tool becomes convex (a "hill" in the center) and the mirror becomes concave (a shallow "bowl").
As grinding progresses, we grind with more center-over-center strokes, which will cause the mirror and tool to become matching spherical surfaces. So that makes it clear to me how you can do it with 2 glass blanks with one being the tool and the other being the mirror. Still doesn't explain to me how you do it with the porcelain tiles method. Unless there is enough thickness in the tiles to wear the tool down to the necessary sphericalness as well as the mirror.
I also forgot to mention the figuring process. The same link above also explains that the figuring is how you go from a spherical curve to a parabolic. I guess there is not much difference in shape if you can make these adjustments with the fine pastes & polishing compounds alone.
I so have to make me an 8" one of these babies. I do not have any astronomy gear yet and will, in about a year, be in a similar situation as the original poster with regards to getting started in astronomy and I just got my DSLR for that aspect of things. I wonder if making my own would be a worthy way of starting out...
I just spent the last hour or so googling and investigating this since his comment. I love making stuff so this intreagued me.
There is plenty of stuff out there about it. Basically you start from a blank piece of plate glass or Pyrex (or portals it seems) and you make yourself the 'tool'- The tool is a convex shaped lump usually with small porcelain tiles on the working surface (A glass tool was traditionally used but this means using a second blank just for that so making your porcelain tiled tool is cheaper for the DIYer). The tool is made using the glass blank as a mould to get the approximate curvature for the tool correct.
Then with the 'tool' you work through differing grades of carbide grinding pastes, then aliminium oxide paste until you get the curve close. Then for the polishing, you cover the tool in optical grade pitch (a gooey stuff from trees or something), and then use fine polishing compound that I have forgotten the name of.
Then you need to get the glass coated in a suitably reflective surface, usually aluminium it seems.
2 things that bug me about this. (Things I did not work out before getting back to work)
1. How do you make the 'tool' curved on a flat blank. I assume you need to do the rough cut first and I did not find anything about this. 2. Depositing the aluminium is apparently done by specialists with vacuum chambers, thus taking it out of the DIY realm. This bothers me. I don't mind buying premade blanks but it'd be nice if all the processes could be DIY.
I'm sure there are easy to find answers to those 2 points but I will find them if I ever try to make one myself - an intreaguing prospect when I have a house.
I find it is pretty good at what it runs. The problem is that for me, the kind of things it runs are the things that I can get on Linux natively anyway.
The things it falls short on are things like the latest office products, latest adobe products and some of the games I like to play. It's helpful in places but does not yet close the gap for me.
How many time critical applications do any of us really use though?...
if you happen to spend 5-10 seconds waiting for your message to get through. A 5-10 second response time on an SSH shell is unbearably slow. Those kind of response times are simply unusable for some.
Personally I find that GTorrent is the best. But somehow I just can't get over the nostalgic value inherent in JTorrent and STorrent. Anyone feel the same like this?
Sure, you're doing 30mph, car coming towards you is doing 30mph, closing speed of 60?
If both cars are equal weight and the collision is straight-on, they will both experience a deceleration from 30mph to 0mph. Exactly the same as if they each hit a wall at 30mph. Only if they have identical energy absorbing crumple zones. Well, identical in that they absorb the energy at the same rate per distance/time of crumpling.
In a decade or two it will probably all be e-ink based so there will be no difference. Except it would need to be illuminated in the dark.
Unless they make a hybrid with oled in the dark and e-ink in the light. Then a light background would waste electricity at night and strain your eyes more.
So have a dark background at night and a light background during the day like reading paper, that's it, web pages that adjust their display depending upon your surroundings.
I don't know if we have enough now, but surely if we DO have enough pi that any errors in the count introduced from the inaccuracy of pi are significantly less than 1 atom, then it would be sufficient, oder?

1. Double click on an mp3 (or any media file really). 2a. Totem opens up, but says it does not have the correct codec. 2b. Totem goes on to tell you it can download the correct codec if you like, you click on yes and enter your password when it asks for it. 3. You listen to your mp3/watch your movie.
I gotta say that's pretty fkin easy. Windows media player would always *try* to do the same but failed for most media files I threw at it, resulting in me having to go googling for codec packs to install.
I think Ubuntu wins this one hands down. It has played everything I have thrown at it so far.
I know this comment is of no intrinsic value to/. But bloody hell those things bloody piss me right off!
With this article it was almost like that "don't touch the wire" game - slowly edging the mouse down through the minefield of text bombs ready to go off in your face at the slightest hint of mousage.

I think the rockers stole it.
Thanks! An extensive read of that stellafane site and your comments have made it all very clear to me now.
Defo gonna make one next year. I think I can manage an 8" f/6.

It's the yank way of saying it. Very very odd.

Seemingly neither do the people in the comments section at the bottom of TFA :-(
Worrying.
Their genes have been spliced...

Maybe I should have kept that to myself...
Yep, and according to the diagrams in there, you have 4 greens, 2 blues, 2 reds and 8 of the new ones in one 'pattern block'
i.e.
for every 2 greens you get 1 red, 1 blue and 4 of the new ones.
Actually it would be 5th 6th 7th and 8th as there is one new pixel for each of the existing pixels.
The summary says the extra pixel is a 4th, but surely it is a 5th. 2*Green 1*Red 1*Blue and then the new one.
We have a LOT of Pi now don't we?
I don't know if we have enough now, but surely if we DO have enough pi that any errors in the count introduced from the inaccuracy of pi are significantly less than 1 atom, then it would be sufficient, oder?
Want pie now!
"Scientists noticed that whenever an airplane would crash, they'd search through the wreckage and the only thing that ever survives intact are these cute little baby dolls. So they built Starbug out of the same stuff."
How much is lost from people holding flourescent lights underneath them?
this would be his post if he did s/A/B on it:
:)
So "s/B/B" is just a cute way of saying, "I think that by B you meant B"?
get it? if you want to replace all A's with B's, do it to *ALL* of them
These maybe? (Rather than the jeff Han one)
