A Complete Understanding is No Longer Possible

[An important reminder for older programmers; we grew up in a different world. -egg]

A Complete Understanding is No Longer Possible:

Let’s say you’ve just bought a MacBook Air, and your goal is to become master of the machine, to understand how it works on every level.

Amit Singh’s Mac OS X Internals: A Systems Approach is a good place to start. It’s not about programming so much as an in-depth discussion of how all the parts of the operating system fit together: what the firmware does, the sequence of events during boot-up, what device drivers do, and so on. At 1680 pages, it’s not light summer reading.

To truly understand the hardware, Intel has kindly provided a free seven volume set of documentation. I’ll keep things simple by recommending Intel 64 and IA-32 Architectures Software Developer’s Manual Volume 1: Basic Architecture (550 pages) and the two volumes describing the instruction set (684 pages and 704 pages respectively).

Objective-C is the language of OS X. We’ll go with Apple’s thankfully concise The Objective-C Programming Language (137 pages).

Of course Objective-C is a superset of C, so also work through the second edition of The C Programming Language (274 pages).

Now we’re getting to the core APIs of OS X. Cocoa Fundamentals Guide is 239 pages. Application Kit Framework Reference is a monster at 5069 pages. That’s help a file-like description of every API call. To be fair I’ll stop there with the Cocoa documentation, even though there are also more usable guides for drawing and Core Audio and Core Animation and a dozen other things.

Ah, wait, OpenGL isn’t part of Cocoa, so throw in the 784 page OpenGL Reference Manual. And another 800 pages for OpenGL Shading Language, Second Edition.

The total of all of this is 79 pages shy of eleven thousand. I neglected to include man pages for hundreds of system utilities and the Xcode documentation. And I didn’t even touch upon the graphics knowhow needed to do anything interesting with OpenGL, or how to write good C and Objective-C or anything about object-oriented design, and…

Winged, kinetic rings that flap

Winged, kinetic rings that flap:

Jeweler/metalworker Dukno Yoon makes beautiful, animated kinetic winged rings, sculptures and towers that flap when you flex your finger.


The contrast between metal structural form and natural feather, together with the repetitive and whimsical movements of fragile wings, provokes the imagination and evolves the intimate relationship between work and viewer/wearer.

Although the recent series, segmented wings have been focused on the formal challenge to engineer an intricate movement that simulates bird wings,

these works are intended to be a series of poems in which I develope my own formal language, interpret the nature of wings, create various structural forms with movements, and share the metaphor, imagination, humor, with viewer/wearer.

Ten stone baby teased with chocolate

[Odd. -egg]

Ten stone baby teased with chocolate:

Entertainment in 1935. “The trouble is nowadays he refuses to be weighed at all so we don’t really know if he’s solid or hollow.”

[Video Link]

Ten Stone Baby, a British Pathe newsreel from 1935.

Despite the newsreel’s original title “Ten Stone Baby”, the boy Leslie Downes is actually 3-years-old. Seen with his parents in a kind of pen, Leslie is sat in an armchair. Somebody then dangles a bar of chocolate into the pen and he immediately sets to work at fetching it.

We also see Leslie playing with bricks.


Bizarre TV interview with Senate candidate and his 5-year-son

[Creeporama -egg]

Bizarre TV interview with Senate candidate and his 5-year-son:

Watch the father’s lips when his kid talks. I don’t know what is going on here, but Mediaite offers three explanations:

1. That the boy has a earphone in and his dad is telling what to say and, for some reason, thinks he’s a much better ventriloquist than he actually is.

2. That Hudson’s responses were all scripted and Hinckley can’t help but mouth his brilliant dialogue.

3. Hudson is actually some kind of AI-style android that is being controlled by its “father.”
Either way, this video is absolutely insane

A fourth possibility is that the dad is nervous about what his son is going to say, and he is echoing the kid’s replies, in a sort of Clever Hans kind way. Please offer up other possibilities in the comments.

Suit made from a drop-cloth

Suit made from a drop-cloth:

This “drop cloth suit” was made by Sarah Bahr and Hugh O’Rourke by cutting a pattern out of a well-used, well-loved drop cloth and tailoring appropriately.


I had the great pleasure of collaborating with fellow artist and friend Hugh O’Rourke on a super fun project. Hugh is a painter and sculptor here in NYC, you can view more of his work here. We met during my thesis art exhibit at NYU, as he works at the 80WSE gallery where I exhibited my installation. He knew my passion for sewing clothing and asked me to collaborate with him in making a suit out of his drop cloths from his studio. The idea of the suit came from famous artist Joseph Beuys’ own sculpture Felt Suit.

Breaking Good: how to synthesize Pseudoephedrine (Sudafed) From N-Methylamphetamine (crystal meth)

[Ha!! -Egg]

Breaking Good: how to synthesize Pseudoephedrine (Sudafed) From N-Methylamphetamine (crystal meth)

Genius scientific paper* of the day: “A Simple and Convenient Synthesis of Pseudoephedrine From N-Methylamphetamine, by O. Hai and I. B. Hakkenshit.” (PDF).

A response by annoyed Sudafed users to the onerous demands by pharmacies for ID and tracking, due to the fact that this helpful and common over-the-counter drug can be used to manufacture crystal meth.

Snip from the paper:

A novel and straightforward synthesis of pseudoephidrine from
readily available N-methylamphetamine is presented. This
practical synthesis is expected to be a disruptive technology
replacing the need to find an open pharmacy.

Pseudoephedrine, active ingredient of Sudafed®, has long
been the most popular nasal decongestant in the United States
due to its effectiveness and relatively mild side effects [1]. In
recent years it has become increasingly difficult to obtain
psuedoephedine in many states because of its use as a
precursor for the illegal drug N-methylamphetamine (also
known under various names including crystal meth, meth, ice,
etc.)[1,2]. While in the past many stores were able to sell
pseudoephedrine, new laws in the United States have
restricted sales to pharmacies, with the medicine kept behind
the counter. The pharmacies require signatures and
examination of government issued ID in order to purchase
pseudoephedrine. Because the hours of availability of such
pharmacies are often limited, it would be of great interest to
have a simple synthesis of pseudoephedrine from reagents
which can be more readily procured.


A quick search of several neighborhoods of the United
States revealed that while pseudoephedrine is difficult to
obtain, N-methylamphetamine can be procured at almost any
time on short notice and in quantities sufficient for synthesis
of useful amounts of the desired material. Moreover,
according to government maintained statistics, Nmethylmphetamine is becoming an increasingly attractive
starting material for pseudoephedrine, as the availability of Nmethylmphetamine has remained high while prices have
dropped and purity has increased [2]. We present here a
convenient series of transformations using reagents which can
be found in most well stocked organic chemistry laboratories
to produce psuedoephedrine from N-methylamphetamine.

Types of vagabonds, 1566

Types of vagabonds, 1566:

The following is a list of the “23 Types of Vagabonds” as identified in a 1566 book by Thomas Harman called “A Caveat or Warning for Common Cursitors, vulgarly called vagabonds.” These “types” were the chapter titles and a decade later compiled into a list in William Harrison’s book “Description of Elizabethan England, 1577” I’m not sure why “male beggar children” are categorized as “Of Womenkind” unless it’s being suggested that they should be under the care of their mothers. From Lists Of Note:

1. Rufflers (thieving beggars, apprentice uprightment)

2. Uprightmen (leaders of robber bands)

3. Hookers or anglers (thieves who steal through windows with hooks)

4. Rogues (rank-and-file vagabonds)

5. Wild rogues (those born of rogues)

6. Priggers of prancers (horse thieves)

7. Palliards (male and female beggars, traveling in pairs)

8. Fraters (sham proctors, pretending to beg for hospitals, etc.)

9. Abrams (feined lunatics)

10. Fresh-water mariners or whipjacks (beggars pretending shipwreck)

11. Dummerers (sham deaf-mutes)

12. Drunken tinkers (thieves using the trade as a cover)

13. Swadders or peddlers (thieves pretending to be peddlers)

14. Jarkmen (forgers of licenses) or patricoes (hedge priests)

Of Womenkind:

1. Demanders for glimmer or fire (female beggars pretending loss of fire)

2. Bawdy baskets (female peddlers)

3. Morts (prostitutes and thieves)

4. Autem morts (married harlots)

5. Walking morts (unmarried harlots)

6. Doxies (prostitutes who begin with upright men)

7. Dells (young girls, incipient doxies)

8. Kinchin morts (female beggar children)

9. Kinchin does (male beggar children)
