Most traders ignore this vital truth about altcurrencies

I’ve been want­i­ng Ron­PaulCoin(RPC) for some time. I’m not bull­ish on the cur­ren­cy, in fact, I think it’s a bad idea. Nam­ing a cur­ren­cy after a per­son­al­i­ty, espe­cial­ly a liv­ing one (Tes­la­coin could be kind of cool) is a ter­ri­ble idea. But espe­cial­ly because Ron Paul is such an anti-fiat-cur­ren­cy gold­bug, I thought it would be fun­ny to have one RonPaulCoin.

Back when Ron­PaulCoin was trad­ing around $18 it was too much, even for the nov­el­ty. I … Read the rest

Bitten by $_REQUEST

Total­ly unre­lat­ed to The Vam­pire Rule,1 today I got a prac­ti­cal les­son in PHP request precedence.

I’ve seen for years rec­om­men­da­tions not to use the super­glob­al $_REQUEST along with a vari­ety of expla­na­tions why to avoid it. These expla­na­tions stem from the pos­si­bil­i­ty that one could be con­fused about the source of the infor­ma­tion from $_REQUEST and end up get­ting some data oth­er than the data one expects to see. It was exact­ly this rea­son that I have been … Read the rest

Breaking a perfectly good fuel pump

My Moto Guzzi has been run­ning pret­ty rough late­ly. It would­n’t start on my trip into San Fran­cis­co for a doc­tor’s appoint­ment the day before Inde­pen­dence Day and I had to get it trail­ered back to Alame­da. A cou­ple of months ago I had a sim­i­lar-seem­ing issue which was an elec­tri­cal prob­lem, but this did not seem elec­tri­cal. The starter motor turned the engine over with vig­or but the darn thing would not catch.

Next on my list of usu­al sus­pects … Read the rest

The pin in the Brembo

It’s way past time for the rear brake pads on the Guzzi to be replaced. I’ve been putting it off for too long think­ing that I don’t real­ly use my rear brake that much any­way. Of course, that’s ter­ri­ble rea­son­ing for at least three reasons.

First, it’s ter­ri­ble rea­son­ing because I ought to use my rear brake. The front brake is always going to do more work, but why not let the rear brake do its part too? Novice rid­ers … Read the rest

Performance on Mac Pro RAID

It’s prob­a­bly a bit late in the game to be review­ing the per­for­mance of a four year old prod­uct, but one more set of bench­mark results in the world can’t hurt much, and may shed some light on more gen­er­al ques­tions about RAID per­for­mance in dif­fer­ent configurations.

Test­ing was per­formed on an 8‑core 2008 Mac Pro with the Apple Mac Pro RAID card and four 15,000RPM SAS dri­ves. The dri­ves were for­mat­ted in between tests and … Read the rest

Photoshop scratch, system swap, and solid state

The first rule of Pho­to­shop club is: don’t let Pho­to­shop use the sys­tem disk as a scratch disk. It’s a good rule of thumb and it has helped many peo­ple get much bet­ter per­for­mance from their Pho­to­shop sys­tems. It’s helped even more peo­ple think they were get­ting bet­ter per­fo­mance from their Pho­to­shop systems.

The prin­ci­ple is straight­for­ward: Pho­to­shop is prone to using more mem­o­ry than the sys­tems on which they run have. When mod­ern oper­at­ing sys­tems run out of mem­o­ry, … Read the rest

NeoOffice

I admit it. I hate Microsoft Office. I’m con­stant­ly appalled at how bloat­ed and com­pli­cat­ed it is even to do sim­ple things. I won’t write in Word, most­ly because I’ve nev­er been able to sim­ply sit down and write with it. Maybe I’m too eas­i­ly dis­tract­ed? I know I don’t have the time to try to fig­ure out how to sim­pli­fy the inter­face by get­ting rid of use­less tool­bars and turn­ing off annoy­ing pop-ups that sec­ond-guess what I’m try­ing to … Read the rest

How I became a Java expert

I was teach­ing myself C out of the Kernighan and Ritchie book (sec­ond edi­tion, so you know I’m a poseur john­ny-come-late­ly) when I tried to pick up Java. This was 1996 and my head was filled with «what if» sce­nar­ios that are still as absurd today as they were then. You know, like «what if all appli­ca­tions were Open­Doc com­po­nents writ­ten in Java?» Which is sec­ond only to «why can’t we all just get along?» in it’s naïveté. But any­how, … Read the rest

Apple’s Bad News and Good News

For back­ground, please read the arti­cle from news.com.

I don’t know why I care much about the fate of Apple, but I’ve been try­ing to fol­low this sto­ry along, and I am hope­ful about Apple’s future. Although I still would­n’t buy a Mac for myself (we’ll see how their NeXT-gen­er­a­tion machines look? I’m keep­ing an Open­Mind on this issue 🙂 ), I think that Apple has been a great pres­ence in this indus­try and that it would be a … Read the rest
