SSL on a Beaglebone Black: balancing performance with security

I’ve recent­ly set up a local serv­er on a Bea­gle­bone Black, which is a cred­it-card sized com­put­er with a 1GHz ARM Cor­tex-A8 proces­sor. I’m using it as a cloud serv­er to sync my cal­en­dar and con­tacts, hav­ing moved the own­Cloud instance (men­tioned the oth­er day) from my host­ed VPS to my local network.

I cre­at­ed a self-signed cer­tifi­cate author­i­ty and an SSL cert for the serv­er and dis­cov­ered that, con­trary to most of my expe­ri­ence run­ning … Read the rest

Owning my own data

I final­ly got sick and tired of the sync dance with Apple and Google not want­i­ng to talk to one anoth­er. I use a Mac but I also have an iPad and since recent­ly I now have an Android phone. I had been sync­ing with iCloud and a long time ago I import­ed all my con­tacts into Google, but I haven’t had sync on that for quite a while.

After tear­ing my hair out try­ing to come up with a way … Read the rest

Why I’m not upgrading to Omnifocus 2

I like Omni­fo­cus1 a lot. I can’t say that I’ve mas­tered it to the point where it has ful­ly become a trust­ed repos­i­to­ry for my tasks, but it is use­ful for keep­ing track of the things I have to do. The new ver­sion looks great. I got the demo ver­sion to test out before buy­ing the upgrade and it is a big improve­ment. The price tag is some­what high but in my opin­ion it’s a worth­while upgrade.

So why … Read the rest

Bagged my first Messier

Two nights ago I went out with the tele­scope to look at the Moon and the plan­ets. Right now the moon is so bright and late­ly the air has been so hazy that even though I would like to start look­ing for oth­er kinds of objects, it’s got to wait for some time that I can get up into the hills and away from the City. But I end­ed out there until after the Moon had not prop­er­ly set but … Read the rest

Is calling Buddhism «stupid» unconstitutional?

An ear­ly ver­sion of this sto­ry referred to Sabine Parish as Sabish Parish. Mono­chro­mat­ic Out­look regrets the error.

There has been a lit­tle con­tro­ver­sy over the case of Lane v Sabine Parish and the ques­tion of whether a teacher telling a kid that his fam­i­ly’s reli­gion is «stu­pid» is uncon­sti­tu­tion­al. One side says the Con­sti­tu­tion pro­vides «sep­a­ra­tion of church and state» (words which do not appear in the Con­sti­tu­tion) and the oth­er side says that the idea of such sep­a­ra­tion has … Read the rest

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

Das Keyboard: feel the noise

It seems a lit­tle strange to refer to Das Key­board as «the Das Key­board» because of course «das» means «the». It’s some­thing like ask­ing for the «hot sal­sa picante sauce», except that «key­board» is not Ger­man for «key­board», plac­ing Das Key­board firm­ly in the realm of brand­ing. Das Key­board isn’t even made by a Ger­man com­pa­ny — the key­boards are man­u­fac­tured in Tai­wan and they are designed and sold by a com­pa­ny in Austin Texas.1

Economists value life more than you do

Bryan Caplan’s 20 Jan­u­ary post at Econ­Log presents an inter­est­ing ques­tion of the sort that is often over­heard at par­ties and cof­fee­hous­es as an exam­ple of a ques­tion that ought not be asked. How do you put a val­ue on a human life?

The ques­tion comes up after some judge or jury awards dam­ages in a wrong­ful death suit, or some news item in nature both lurid and legal­is­tic. Usu­al­ly the dis­cus­sion nev­er gets past the notion that life is price­less. … Read the rest

If you like getting the runaround, you can keep getting the runaround

Most Amer­i­cans ought to be famil­iar with the recur­ring gag in the com­ic strip Peanuts in which every year Lucy offers to hold the foot­ball so that Char­lie Brown can kick it. Each year, Char­lie Brown com­plains that Lucy nev­er acts in good faith and that she always pulls the ball away at the last minute, leav­ing poor Char­lie Brown flat on his back after a flubbed kick attempt. Lucy invari­ably comes up with a com­pelling argu­ment why Char­lie Brown … Read the rest

Now and then, step outside social media’s walls

I don’t usu­al­ly make New Year’s Res­o­lu­tions for a vari­ety of rea­sons. For more on the sub­ject, see Res­o­lu­tion Evo­lu­tion by Jason McClain. How­ev­er, this year I have a some­what dif­fer­ent tack. I’m com­mit­ting myself not to a set of spe­cif­ic pass/fail tasks (make it to the gym every day) but to a more gen­er­al goal: reduce my use of social media sites as my con­duit to blogs.

There is a prob­lem with the Web that has yet to be … Read the rest
