Charla: aplicaciones extensibles con PyQt

Span­ish on­ly, since it's about a video in span­ish ;-)

Acá es­tá, gra­cias a la gente de Junín, un video de mi char­la "Apli­ca­ciones ex­ten­si­bles us­an­do PyQt", en la que in­ten­to mostrar co­mo de­sar­rol­lar una apli­cación con PyQt y yap­sy.

No es una char­la con la que es­té muy con­tento. La otra sal­ió mejor, pero no se filmó, así que quedará so­lo en la memo­ria de los cu­a­tro gatos lo­cos que es­tábamos ahí ;-)

El resto de las char­las: http://un­no­ba.blip.tv/

The market is down because... [sound of shaking magic 8-ball]

Let me share with you a piece from Mon­ey Cen­tral, but I am not pick­ing on them, you can find the same crap on ev­ery news­pa­per or TV chan­nel's fi­nan­cial sec­tion:

The push to dump stocks came in re­sponse to news that ar­tillery fire was ex­changed overnight be­tween North Ko­rea and South Ko­re­a. Though ten­sion be­tween the two na­tions has been per­sis­ten­t, the lat­est episode marks a dra­mat­ic es­ca­la­tion of the tone be­tween them.

That de­vel­op­ment added to the dis­tress of mar­ket par­tic­i­pants, who have long held con­cern for the frag­ile state of fi­nances among coun­tries in the Eu­ro­pean Union pe­riph­ery. Even Ire­land re­mains a point of wor­ry as it has yet to com­plete­ly struc­ture a bailout pack­age and im­ple­ment aus­ter­i­ty mea­sures.

Dis­tress and un­cer­tain­ty moved many in­to the rel­a­tive safe­ty of the dol­lar, which was up 1.3% against com­pet­ing cur­ren­cies at the close of trade. The ad­vance marked its big­gest one-­day bounce in a month and put the cur­ren­cy at its best lev­el in al­most two month­s.

But my ti­tle is a lie, these guys are not look­ing at a mag­ic 8-bal­l. What they are look­ing at is the rest of the news­pa­per. Let me share the recipe:

  1. See if the mar­ket is up or down.

  2. Up? Then look at the news and check for good news.

    1. What? No im­­­por­­­tant god news? Awe­­­some! Then fig­ure out how some­thing that looks bad is ac­­­tu­al­­­ly good. That's a gold­en chance to be de­­­clared in­­­sight­­­ful.

    2. Good news? Bin­­­go, that's why the mar­ket is up.

  3. Down? Look at the news and check for bad news.

    1. Bad news? Ok, that's why.

    2. No big bad news? Great! Then some­thing that's good needs to be de­scribed as "caus­ing un­cer­­­tain­­­ty"

In the re­al world, the busi­ness an­a­lysts have on­ly the fog­gi­est no­tion of why the mar­kets move as they do. In fac­t, if they had a no­tion, the mar­ket wouldbe pre­dictable. If it were pre­dictable, then savvy in­vestors would beat the mar­ket.

And that does­n't hap­pen.

Veracity

Review:

Imag­ine a book writ­ten com­plete­ly from the point of view of a mis­an­thrope. Now imag­ine said mis­an­thrope is prone to sopho­moric men­tal ram­blings. Add some en­dear­ing fea­tures such as be­liev­ing he is smarter than any­one else. Add a lot of oth­er var­ied mis­an­thropes as char­ac­ter­s. Now make them com­plete­ly uni­di­men­sion­al, so you can de­fine each of them in one line ("On­ni is nice and makes mu­sic"). Put those char­ac­ters in a brief, not very in­ter­est­ing jour­ney where not much hap­pens ex­cept that they are all de­struc­tive mo­ron­s.

Now, take those in­gre­di­ents and use them to write a book. That book is Ve­rac­i­ty by Mark La­vo­ra­to.

The Space Pioneers

Review:

It's pulp. It's very old. It's aimed at kid­s. It's part of the "Tom Cor­bet­t: Space Cade­t!" se­ries. So, it is kin­da fun, if you can look the oth­er way when­ev­er it gets re­al­ly sex­ist, or sil­ly, but I can't quite rec­om­mend it to any­one.
