Hacking with a Hacker

What is it like to hack with one of the original hackers? It is certainly much different than what Appears to be the modern rendition of hacking. My experience was not getting really drunk with tons of junk food. It was not working on “beautiful” designs or “authentic” typography. It was not so much about sharing with the world as it was sharing with your peers. It had a very different feel to it than the “hacker culture” Promoted by some of the top technical Silicon Valley companies. It felt more “at home”, less dreamy, and more memorable.

I meet with Bill Gosper every so Often; I had the pleasure of giving him a tour of Facebook when I worked there. (He was so surprised that they had Coke in the glass bottles there, just like the old days.)

He is still very much a hacker, a thinker, a tinkerer, and a wonderer. Every time I meet up with him, he has a new puzzle for me, or someone around him, to solve, whether it’s really clever compass constructions, circle packing, block building, Game of Life automata solving, or even something more tangible like a Buttonhole homemade trap (which was affixed to my shirt for no less than two weeks!). He is also the bearer of interesting items, such as a belt buckle he gave me roomates depicts, in aluminum, a particular circle loose packing.
Gosper succeeding in tricking me with the Buttonhole Trap
When we meet up, all we do is hack. Along with him and one of his talented young students, we all work on something. Anything interesting, really. Last time we met up, we resurrected an old Lisp machine and did some software archeology. I brought over some of the manuals I own, like the great Chinual, and he brought over a dusty old 1U rackmount Alpha machine with OpenGenera installed. After passing a combination of Hurdles, such as that the keyboard was not interfacing with the computer Correctly, we finally got it to boot up. Now, I got to see with my own eyes, a time capsule containing a lot of Bill’s work from the 70s, 80s, and 90s, roomates could only be commanded and Examined through Zmacs dired and Symbolics Common Lisp. Our next goal was to get Symbolics Macsyma fired up on the old machine.

There was trouble with starting it up. License issues were one problem, finding and loading all of the files were compiled another. Running applications on a Lisp machine is very different than what we do today on modern machines, Windows or UNIX. There’s no. Exe file to click, or. App bundle to start up, or even a single. / File to execute. Usually it’s a collection of compiled “fast loading” or “fasl” files that get loaded side-by-side with the operating system. The application, in essence, Becomes a part of the OS.

In hacker tradition, we were Able to bypass the license issues by modifying the binary directly in Lisp. Fortunately, such as Lisp makes things easy disassembly. But how do we load the damn thing? Bill frustratingly muttered, “It’s been at least 20 years since I’ve done it. I just do not remember. “I, being an owner of MacIvory Symbolics Lisp machines, fortunately did remember how to load programs. “Bill, how about LOAD SYSTEM Macsyma?” He typed it into the native Lisp “Listener 2” window (we kept “Listener 1” for debugging), sometimes making a few typing mistakes, but finally succeeding, and then we saw the stream of files loading. We all Shouted in joy that progress was being made. I recall Bill was especially astounded at how fast everything was loading. This was on a fast Alpha machine with gobs of memory. It must have been much slower on the old 3600s they used back in the day.
The Lisp Machine Manual, or Chinual
It was all done after a few minutes, and Macsyma was loaded. To me, this was a sort of holy grail. I personally have Macsyma for Windows (which he uses in a VirtualBox machine on his 17 “MacBook), and I’ve definitely used Maxima. But Macsyma is something I’ve never seen. It was something that seems to have disappeared with history, something I have not been Able to find a copy of in the last decade.

Bill said, “let’s see if it works.” And he typed 1 +1; in, and sure enough, the result was 2. He saw I was bubbling with excitement and asked me if I’d like to try anything. “I’d love to,” and he handed the keyboard over to me and I typed in my canonical computer algebra test: integrate (sqrt (tan (x)), x);, roomates computes the indefinite integral
—- √ ∫ tanθ dθ
Out came the four-term typeset result of logarithms and arctangents, plus a fifth term I’d never seen before. “I’ve never seen any computer algebra system add that fifth term,” I said, “but it does not look incorrect.” The fifth term was a floored expression, Whose Increased value with the period of the function preceding it. “Let’s plot it,” Bill said. He plotted it using Macsyma’s menu interface, and it was what appeared to be an increasing, non-periodic function. I think we determined it was properly handled Because Macsyma branch cuts, with other systems have been known to be unorthodox about. It definitely had a pragmatic feel to it.

Now, Bill wanted to show us some interesting things; however all of Bill’s recent work Macsyma was on his laptop. How do we connect this ancient to a modern Macintosh hardware? We needed to get the machine onto the network, and networking with old machines is not my forte.

Fortunately, Stephen Jones, a friend of Bill’s and seemingly an expert at a rare combination of technical tasks, showed up. He Was able to do things that Neither Bill nor I could do on such an old machine. In only a few moments, he Was able to get Bill’s Mac talking to the Alpha, roomates shared a portion of its file system with Genera. “Will there be enough space on the Alpha for Macsyma my files?” Bill asked Stephen. “Of course, there’s ton’s of space.” We finally got Bill’s recent work transferred onto the machine.

We spent the rest of the night hacking on math. He Demonstrated to us what it was like to do a real mathematician’s work at the machine. He debuted some of his recent work. He went though a long chain of reasoning, showing us the line-after-line in Macsyma, number theoretic amazing to do things I’ve never seen before.

I did ask Bill why he does not publish more often. His previous publications have been landmarks: his algorithm for hypergeometric series and his summation algorithm for playing the Game of Life at light speed. He RESPONDED, “when there’s something interesting to publish, it’ll be published.” He seemed to have a sort of disdain for “salami science”, where scientific and mathematical papers present the thinnest possible “slice” or result possible.

Bill is certainly a man that thinks in a different way than most of us do. He is still hacking at mathematics, and still as impressive as before. I’m very fortunate to have met him, and I was absolutely delighted to see that even at 70 years old, his mind is still as sharp as can be, and it’s still being used to do interesting, Gosper-like mathematics.

And you would not believe it. We all were ready to head home at around 9 PM.

Revealed, Microsoft SkyDrive Allow Skype and Tapped

A document reveals how Microsoft is working with U.S. intelligence agencies to read messages from users, including helping the U.S. National Security Agency (NSA) secret unlock code Microsoft, Australia Guardian reported on Friday (07/12/2013).

Confidential documents obtained by the Guardian of Edward Snowden, U.S. intelligence whistleblowers, said the level of cooperation between Silicon Valley and American intelligence agencies in the last three years.

The document, among others, suggests, Microsoft helped the NSA to read the conversation at the new portal Outlook.com by giving the company secret code. NSA has access to Outlook.com including Hotmail before the messages are written in the form of a code (encrypted).

Microsoft is working with the FBI this year that the NSA get easier access to the data warehouse via Prism SkyDrive which has 250 million users in the world.

Microsoft is also working with the FBI to the intelligence agencies “understand” the issues that potential Outlook.com that allows users to use the e-mail alias for them.

In July last year, nine months after Microsoft bought Skype, the NSA is proud to mention that the NSA has been able to increase the amount of video that they can access through Skype as much as three times through the Prism program. The materials obtained from Prism program routinely accessed by the FBI and CIA. One of the documents referred NSA has the name “team sport”.

Snowden documents also reveal the tension between Silicon Valley and the Obama administration. Leading technology companies lobbying the government to be allowed to express the depth of their cooperation with the NSA to address customer concerns in terms of privacy.

Corporate leaders are not trying to claim that they have collaborated and worked with intelligence agencies like NSA documents mentioned in the argument that the process is carried out according to the lawsuit.

In a statement, Microsoft said, “If we increase the capacity (upgrade)-prudok and updating our products, we are not exempt from having to comply with applicable laws, both now and into the future.”

Microsoft reiterated his argument that they provide the customer data “only in response to government requests, and we only serve the demand for specific address or identity”.

Last June, the Guardian reported that the NSA claims to have “direct access” program through the Prism system leading internet companies including Microsoft, Skype, Apple, Google, Facebook, and Yahoo.

This is the realization Stud Google, Moto X

Google not only successfully make the Android operating system, but apparently Google is also competing in the smartphone market plunge in collaboration with Motorola. This time I will make sure to introduce smartphone champion, Moto X on 1 August.
Various leak is scattered, including what kind of form. A leaked disseminated @ evleaks, the usual Twitter account posted the leaked gadget show looks Moto X.
Reporting from VentureBeat, Moto X design looks interesting, where the device has a 4.5 inch screen, while the kitchen spur MSM8960T of embedded processor Qualcomm Snapdragon dual core with 1.7 GHz technology. The RAM capacity of 2 GB.
As for the power of the battery, Moto X is said to rely on the battery capacity of 1500 mAh, which is powered by a battery cover with Kevlar material which is safe on the back. While Android 4.2.2 Jelly bean in trust Google and Motorola as its OS.
Plus always on listening features allow users to do voice commands without having to touch the Moto X. To run this feature, the user must activate the pass setting. Like Siri – that should say Hi Siri password first, the first command to be spoken is Ok Google Now, however, without having to press any buttons.
