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.

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.

Monitor Asus MX279H

Tempting appearance u6-436-AsusAsus MX279H is one variant of the monitor into the first ranks of Designo MX Series.Hal that steal the show are performances that are the focus of this series.

Rely on the screen with a thin bezel, this LCD monitor performed beautifully accented with metal bar which also serves as the setting panel on the bottom right side. Circular buffer is designed as though the actual form of metal plastic.

The buttons are there on the Asus MX279H, although there are physical, but it just needs to be touched. True, Asus chose to use the touch buttons on the LCD monitor with a diagonal screen size of 27 ˝ this. The arrangement itself is quite comprehensive, ranging from the standard setting brightness, contrast, until saturation. There is also the selection of presets like Scenery, Theater, Game, Night View, and in which each of these presets you can still set it again.

In terms of connectivity, this Asus monitor provides two HDMI ports, a single D-Sub 15pin port, and two audio ports (Headphone Out and Line In). Asus nullify the decision and choose the DVI connector HDMI connector types may recall this now more popular and is found in many devices. Interesting features contained in this MX279H Asus Asus SonicMaster is in charge of presenting the best sound for the class of integrated speakers on the monitor.

At PCplus testing for the audio quality, speaker Bang and Olufsen ICEpower sound produces above average speaker monitor in general. The audio system can not replace a desktop audio system, especially if you expect thumping bass. Power output or volume is enough to fill the room. So for everyday use such as watching streaming video or simply listen to soft music, the sound produced by Asus PCplus MX279H sufficient.

Asus uses AH-IPS panel type on MX279H to provide a good quality display. Panel is fairly dark frame design make it blend with the screen so that the state of death, this LCD monitor looks completely frameless. Facilitate the availability of several presets that you do not want to mess around with these settings and it. In general appearance was good, with the brightness and contrast level is fairly good. However, PCplus found that the saturation level of the monitor is a bit high, so as to obtain the best view, PCplus suggest to keep it set.

Living in and Loving Uptown Dallas

Fresh off my divorce and having just earned my college degree at the ripe old age of 43, I landed my first professional job in Dallas, Texas. I checked out many areas of the city and decided to plant my roots in a vibrant community with great shopping, restaurants and parks to explore. I spent many hours looking at apartments in Dallas Uptown before settling on one that had absolutely everything I ever dreamed of and was completely opposite of the rural country house I had spent the last 18 years of my life in.

It was a conscious decision to change my lifestyle completely. Not because I hated my ex-husband or the life we had been leading, but I knew I needed to escape the easy complacency of living in the same town I had been born in, grew up in and lived in all of my life. Continue reading

Official feedback on OpenGL 4.4 thread

 SIGGRAPH – Anaheim, CA – The Khronos™ Group today announced the immediate release of the OpenGL® 4.4 specification,bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface). OpenGL 4.4 unlocks capabilities of today’s leading-edge graphics hardware while maintaining full backwards compatibility, enabling applications to incrementally use new features while portably accessing state-of-the-art graphics processing units (GPUs) across diverse operating systems and platforms. Also, OpenGL 4.4 defines new functionality to streamline the porting of applications and titles from other platforms and APIs. The full specification and reference materials are available for immediate download at http://www.opengl.org/registry.

In addition to the OpenGL 4.4 specification, the OpenGL ARB (Architecture Review Board) Working Group at Khronos has created the first set of formal OpenGL conformance tests since OpenGL 2.0. Khronos will offer certification of drivers from version 3.3, and full certification is mandatory for OpenGL 4.4 and onwards. This will help reduce differences between multiple vendors’ OpenGL drivers, resulting in enhanced portability for developers.

New functionality in the OpenGL 4.4 specification includes:

Buffer Placement Control (GL_ARB_buffer_storage)
Significantly enhances memory flexibility and efficiency through explicit control over the position of buffers in the graphics and system memory, together with cache behavior control – including the ability of the CPU to map a buffer for direct use by a GPU.

Efficient Asynchronous Queries
(GL_ARB_query_buffer_object)
Buffer objects can be the direct target of a query to avoid the CPU waiting for the result and stalling the graphics pipeline. This provides significantly boosted performance for applications that intend to subsequently use the results of queries on the GPU, such as dynamic quality reduction strategies based on performance metrics.

Shader Variable Layout (GL_ARB_enhanced_layouts)
Detailed control over placement of shader interface variables, including the ability to pack vectors efficiently with scalar types. Includes full control over variable layout inside uniform blocks and enables shaders to specify transform feedback variables and buffer layout.

Efficient Multiple Object Binding (GL_ARB_multi_bind)
New commands which enable an application to bind or unbind sets of objects with one API call instead of separate commands for each bind operation, amortizing the function call, name space lookup, and potential locking overhead. The core rendering loop of many graphics applications frequently bind different sets of textures, samplers, images, vertex buffers, and uniform buffers and so this can significantly reduce CPU overhead and improve performance.

Streamlined Porting of Direct3D applications

A number of core functions contribute to easier porting of applications and games written in Direct3D including GL_ARB_buffer_storage for buffer placement control, GL_ARB_vertex_type_10f_11f_11f_rev which creates a vertex data type that packs three components in a 32 bit value that provides a performance improvement for lower precision vertices and is a format used by Direct3D, and GL_ARB_texture_mirror_clamp_to_edge that provides a texture clamping mode also used by Direct3D.Extensions released alongside the OpenGL 4.4 specification include:

Bindless Texture Extension (GL_ARB_bindless_texture)
Shaders can now access an effectively unlimited number of texture and image resources directly by virtual addresses. This bindless texture approach avoids the application overhead due to explicitly binding a small window of accessible textures. Ray tracing and global illumination algorithms are faster and simpler with unfettered access to a virtual world’s entire texture set.

Sparse Texture Extension (GL_ARB_sparse_texture)
Enables handling of huge textures that are much larger than the GPUs physical memory by allowing an application to select which regions of the texture are resident for ‘mega-texture’ algorithms and very large data-set visualizations.

OpenGL BOF at SIGGRAPH, Anaheim, CA July 24th 2013
There is an OpenGL BOF “Birds of a Feather” Meeting on Wednesday July 24th at 7-8PM at the Hilton Anaheim, California Ballroom A & B, where attendees are invited to meet OpenGL implementers and developers and learn more about the new OpenGL 4.4 specification.

Yahoo Sports Launches New Fantasy App With Mobile Drafting

Yahoo announced that it has launched its new 2013 Fantasy Sports app today, which brings a new design, and new features to the experience.

One of the big new improvements is that it now features mobile drafting, which many will find tremendously helpful. It’s a lot of pressure to be at a computer during draft time.

 

“Managers can now sign up, draft a team and win their league championship from their iOS and Android device thanks to new technology incorporated by Bignoggins Production, Loki Studios and the Yahoo! Sports mobile team,” a spokesperson for Yahoo tells WebProNews. “The app also now features mock drafting, to help fans prepare and get an edge on the competition.”

Yahoo announced its acquisition of Bignoggins just a few weeks ago. They haven’t wasted any time.

“And starting with football, for the first time ever, all of Yahoo! Sports Fantasy games will live under one mobile roof – the Yahoo! Sports Fantasy app – including basketball, hockey and baseball,” the spokesperson adds.

According to Yahoo, the new app is faster than previous experiences. It also has free notifications.

The app is available for iOS and Android.

MySpace users threaten to sue after years of blogs deleted

MySpace has been accused of deleting years worth of users’ personal blogs and histories after the site underwent a $20 million relaunch last month.

The move was a bid to shed the site’s outdated image and attract a new teenage fanbase, after millions of users migrated to Facebook as their primary social networking site in the late 2000s.

Purchased by Rupert Murdoch’s News Corporation in 2005 for $580m, a decision Murdoch has since called a “huge mistake”, MySpace’s focus on music and entertainment over social interaction has been credited as one of the reasons behind its decline.

At its peak, the site boasted 125m users and more webpage visits than Google. It now has around 25m users.

In 2011 Specific Media Group and pop heartthrob Justin Timberlake jointly purchased the company for $35m, and have since attempted to rebrand the site for the teenage generation through campaigns with rapper Pharrell.

This sleek new makeover has resulted in the deletion of blogs, videos, private messages, posts and comments without prior warning, much to the fury of its remaining loyal users.

Distraught fans created a thread entitled ‘I want my blogs and classic myspace back’ to vent their frustration at the move one user called “crass arrogance”.

They continued: “You have stolen 6 years of blogs and something that is priceless to me and cannot be replaced.”

Another lamented the deletion of her blogs, writing: “Openly and freely I shared intimate moments that can not be relived or retold for they where experienced. I would revisit myspace religiously because of my blogs… Myspace did an ultimate back stab.” [sic]

MySpace responded to concerns with the soothing message that the information had not been lost forever.

It said: “Change isn’t easy and there has been a lot going on lately. We understand that this information is very important to you. Please understand that your blogs have not been deleted. Your content is safe and we have been discussing the best ways possible to provide you your blogs.”

‘Portable’ computer from 1979 wins CNET’s old tech contest

CNET’s From Old School to Tech Cool Contest asked our Facebook fans to share photos of old tech, with the ten most popular qualifying for a chance to win the Panasonic TC-PST60. This plasma TV is a 2013 Editors’ Choice and the only TV to ever receive a 5-star rating from CNET.

Congratulations to Garret W, whose photo of an old-school portable computer won the contest. TV reviewer David Katzmaier selected the winner from among the top ten vote-getting entries.

“There was a lot of great old tech among the final photos,” said David, “but I liked the ‘portable’ TRS-80 computer from 1979 best. With a monochrome monitor, separate keyboard, archaic peripherals and even a three-ring binder, all encased in a massive wood trunk complete with handles, it shows just how far computing and portable tech have come.”

Thank you to everyone who participated and a special congratulations to the ten finalists with the most user votes. Check out their submissions in the photo gallery below.

Google releases Chrome 28 with Blink browser engine

Google on Tuesday released Chrome 28, the first polished version of the browser to use the company’s home-grown “Blink” rendering engine. On Windows, the upgrade also sported Google’s new notification service that lets developers of Chrome apps and add-ons display messages and alerts outside the browser window.

The upgrade was the first since May 21, when Google shipped Chrome 27 and touted some minor performance improvements.

[ Also on InfoWorld: Bug bounty programs provide strong value for Google, Mozilla. | Get your websites up to speed with HTML5 today using the techniques in InfoWorld’s HTML5 Deep DivePDF how-to report. | Learn how to secure your Web browsers in InfoWorld’s “Web Browser Security Deep Dive” PDF guide. ]

Google announced in April that it was dropping the open-source WebKit browser engine — at the time also used only by Apple’s Safari — and was instead launching Blink, a WebKit variant, to power Chrome. Since then, Opera Software’s Opera has also adopted WebKit as an interim step before it eventually moves to Blink.

Google cited difficulties in adapting WebKit to Chrome, and in the first weeks after the announcement, stripped copious amounts of unnecessary-for-Chrome code from the fork that became Blink. Previously, only the rougher “Dev” and “Beta” builds of Chrome relied on the Blink engine. Users can verify that Blink is present by typing chrome://version/ in the Chrome address-search bar, dubbed the “Omnibox.”

Also included in Chrome 28 is new support for more sophisticated notifications that appear outside the browser pane and display even when the browser’s not running. “Packaged apps” — ber-Web apps that look and behave like “native” code written specifically for the underlying OS — and add-ons can push brief messages and alerts to Chrome users after their developers have enabled the feature.

Only the Windows version of Chrome 28 currently supports these next-generation notifications, but Google promised that the feature would soon make its way to OS X and Linux. On a Mac, Chrome notifications are not integrated with OS X Mountain Lion’s Notification Center.

Along with the debut of Blink and notifications, Chrome 28 contained patches for 15 security vulnerabilities, one of them rated “critical,” Google’s most serious threat ranking. According to Google’s terse security advisory, that flaw was a memory management bug — dubbed a “use-after-free” vulnerability — in the browser’s network sockets code.

But while Colin Payne, who reported the bug, received an impressive reward of $6,267.40, another researcher was handed triple that. Andrey Labunets was paid a record $21,500 for filing several vulnerability reports, including two in the Google synchronization service and an unknown number of others that Google said were “…since-fixed server-side bugs.”

That last phrase and the amount paid were clues that Labunets discovered one or more flaws in a core Google service. In April, Google boosted bounties for vulnerability reports in its core websites, services and online apps, resetting the top reward to $20,000 for remote code executable bugs, those that attackers could use to slip malicious code onto a server or into an app or site.

Labunets is no stranger to large bug bounties. Earlier this year, after reporting a string of weaknesses in Facebook’s authentication protocol, Labunets was awarded $9,500 by the social networking giant.

Altogether, Google this week paid bounties totaling $34,901 to six researchers, including Payne and Labunets, for reporting eight different bugs. Through Tuesday, the Mountain View, Calif., company has awarded nearly $250,000 thus far this year in bounties or hacking contest prizes.

Users can download Chrome 28 from Google’s website. Active users can simply let the automatic updater retrieve the new version.

Asus Memo Pad HD 7 review: Vivid screen barely outshines slow performance

The good: The Asus Memo Pad HD 7 rocks an impressively colorful screen, features a bevy of useful customization options, and comes in at a budget price.

The bad: Its performance is mediocre and the touch screen is sometimes unresponsive. The plastic build gives it a toy-like feel and it isn’t very comfortable to hold. The dull design lacks panache.

The bottom line: For those looking to save a buck, for its low price, the Asus Memo Pad HD 7 has a bevy of useful features, though there are better performing options out there.

With the Asus Memo Pad HD 7, you really get what you pay for. The HD 7 earns its low price with a lackluster design and sluggish performance. It’s not very comfortable to hold for long periods of time, and aside from being offered in a variety of different colors, lacks a coolness other tablets try hard to aspire to.

Its performance is meekly mediocre, and consistent lagging combined with a sometimes unresponsive touch screen make the tablet best suited for simple tasks like browsing and reading.

That said, the HD 7 is a refreshing upgrade from its predecessor and its best feature is the 7-inch IPS screen that displays an impressively wide range of colors which facilitate a visually richer experience than the original Nexus 7.

If you’re on a strict budget, the Asus Memo Pad is an inexpensive and functional small tablet, but if you can spare the change, a new Nexus 7 is the better choice.

Design
Even though the tablet shares similar dimensions with the Nexus 7, it’s nowhere near as sleek or comfortable in design. The tablet fits fine in one hand, even for people with smaller hands like me, yet, despite its light weight, the design doesn’t lend itself to comfortable holding over lengthy periods of time.

The back panel protrudes slightly, and the corners slightly dig into your palms when holding it in both hands, instead of the flush, smoothly curved edges of the original Nexus 7. I often found myself wanting to put the device down after using it for awhile — not because I was done using it — but because holding it became tiresome.

The Asus Memo Pad HD 7 comes in navy blue, white, hot pink, and lime green. The navy blue version is the only one that has a back with a matte finish. The dark shade of blue attracts a minimal amount of fingerprints that are only highly visible from certain angles. The back panel is smooth and comfortable to the touch but can be a bit slippery without a tight grip.

In comparison, the reflective plastic backsides of the other colors looks less chic, but its texture helps one grip the device significantly better than the matte finish does. I personally prefer a back panel with a grippier texture, like the Nexus 7 (2012), because it enhances my comfort level in a way that extends the amount of time I can hold the device.

Since they’re both made by Asus, the Memo Pad HD 7 and the Nexus 7 (2012) share similar design elements. The power button and volume rocker on the right edge look almost identical in shape, while the rear speakers are similarly located towards the bottom edge of the tablet.

The front of the tablet is typically simple, with an Asus logo on the bottom bezel and a front-facing camera on the top. There is no ambient light sensor, therefore no automatic brightness setting.

The Memo Pad HD 7’s headphone jack, microphone pinhole, and Micro-USB port are all located on the top edge, with the microSD expansion slot — which is expandable up to 32GB — around the corner on the left edge. There are no ports on the bottom edge, but the speaker sits on the bottom of the tablet’s back, keeping the 5-megapixel rear camera on top company.

Asus Application Suite
The tablet comes loaded with the Asus Application Suite and features apps that range from useful to creative. The simple additions include a calendar, to-do list, and file manager, and it comes with 16GB of Asus WebStorage cloud service for one year.

Some of the apps that are geared towards family use include App Locker, which allows you to put passwords on specific apps; Asus Artists, where you can create “paintings” or greeting cards; and Asus Story, which helps you organize your photos into albums, or as they call them, “stories.”

The tablet comes with Power Saver, a battery saving feature that comes in handy if you’re trying to squeeze the most out of a low battery.

The custom mode lets you pick the specific functions that the power-saving option affects. For example, you can set a low screen brightness for listening to music, a higher one for watching video, and no power-saving function for reading books. When enabled, it significantly helped extend the battery life when it was low and the highly customizable options.

Floating apps
One of the most interesting and useful features on the tablet is the floating menu. On the Android navigation bar, there’s a button to the left of the back button that activates the floating menu.

When activated, a small menu pops up above the navigation bar that contains a selection of floating apps that you can quickly access without having to close whatever app you’re currently using. Since the apps “float” on the screen, on top of whatever is already open, it’s almost like a multiwindow option, but they can only perform simple tasks and can’t compare to the multiwindow functions that the Microsoft Surface or some of the Samsung Galaxy tablets provide.

Floating apps are an easy way to multitask, and I liked the ability to use the browser while watching video, but not all streaming video services continue to play while a floating app is open. With the exception of a few floating apps, including the calculator and compass, Netflix did not let me use most of the floating apps while simultaneously watching video, although YouTube did.

Despite providing an easy way to multitask, the floating apps don’t have the same functionality as the fullscreen app and are limited in their capabilities; the YouTube app only shows recommended videos — you can’t search — and the Twitter app displays only one tweet at a time. There is a limited amount of floating apps, and although the floating menu is customizable, not all downloaded apps have the ability to be floating ones.

Speaker features
The Memo Pad HD 7 houses stereo speakers with Asus SonicMaster audio technology and Audio Wizard software. Although the speakers aren’t great, the number of specific audio settings are. The tablet allows you to manually adjust separate volume settings for app audio, notifications, and alarms.
