Programming and Life plans.

First a huge an­nounce­men­t: I will not re­lease any­thing to­mor­row. For the first time in 6 week­s, no fri­day re­lease from me!

Now, let's see what I'm plan­ning.

  1. I will be at Lati­noWare 2008 speak­ing about PyQt. The usu­al free beer of­fer: if you men­­tion this blog, I will buy you 1 (one) not very good beer. Be­ing in Brazil, that's prob­a­bly a Brah­­ma.

  2. rst2pdf de­vel­op­­ment is slow­ing down. The easy stuff is all done. There are some things I can do, though:

    • Ex­­­pose tran­si­­­tions to the writ­er (good for pre­sen­­­ta­­­tion­s)

    • "Back­­­­­ground" forms (a­­­gain, for pre­sen­­­ta­­­tion­s)

    • A mini-lan­guage ex­­­pos­ing the can­­­vas, so there is a use­­­ful "raw" mod­­­e.

    • Us­ing svglib in­­­stead of uni­­­con­ver­­­tor to han­­­dle SVG (but keep uni­­­con­ver­­­tor for oth­­­er vec­­­tor for­­­mat­s)

    • Re­­­do­ing list­s, which have a shaky code and bad lay­out

    • Fix half a dozen bugs

    • Make it work more like a unix app when in unix (re­spect en­vi­ron­­­ment vars, for ex­am­­­ple)

    How­ev­er, I am tak­ing a lit­­tle time off from it, and go­ing to try re­­viv­ing oth­­er pro­jec­t­s. Fo­­cus­ing in rst2pdf for two months did won­ders for it. Let's see if it can be re­­peat­ed!

  3. Try some more code golf­ing. I helped Nu­bis from PyAr reach the low­est­-s­­core of 74 in the grid chal­lenge. This is re­al­­ly fun stuff.

  4. I need more mon­ey. We have spent lots in ... plumb­ing. Yup. Two years of sav­ings spent on that. So, I need mon­ey. If you read this blog and want to make me hap­py, get me free­lance work. It can be sysad­min stuff, it can be pro­­gram­ming, it can be babysit­t­ing. I am good at all three things. Con­­tact me. I'm easy to find, and I am cheap­­(ish).

  5. No, I am not starv­ing. No, I am not in mon­ey prob­lem­s. Yes, my com­­pa­ny is do­ing very well, but it's an in­­vest­­men­t, not a cash cow (yet).

Golfing

I spent a few hours to­day round Code Golf and here's a neat thing I did.I think this is python's short­est pos­si­ble fac­to­ri­al:

f=lambda x:x<2or x*f(x-1)

You may say it's not cor­rec­t, be­cause f(1) re­turns True, but in­t(True) is 1, so it's al­most there ;-)

And here's a sur­pris­ing­ly read­able (as long as you know pas­cal's tri­an­gle) and not too long an­swer to their choose chal­lenge:

n,k=input()
a,c=1,0
while c<k:a*=n-c;c+=1;a/=c
print a

The Stars at War (Starfire, #2-3)

Review:

A col­lec­tion of clichés (Niv­en wants his Kzin back, au­thors!), but it moves at a good pace, and is en­ter­tain­ing.

What may be in rst2pdf 0.9...

If I man­age to make it work well: Math!

Here's how it look­s:

rst2pdf-math

It does not re­quire TeX. It is not an im­age. It does re­quire ex­ter­nal soft­ware, and it does re­quire you to write TeX syn­tax.

If you are a re­port­lab user: this is a platy­pus flow­able.

As usu­al, it's not me that's do­ing the heavy lift­ing. I am just good at us­ing oth­er tool­s.

With a lit­tle luck, it should be us­able this fri­day.
