Photographing computers to show the art inside the black box

[Editor’s note: I was utterly taken with the gorgeous photos in the new edition of Core Memory, photographer Mark Richards’s lavish survey of the vintage computing hardware in Silicon Valley’s gem, the Computer History Museum; below is senior curator Dag Spicer’s introduction to the book, along with some photos, which the publisher was kind enough to supply -Cory]

What computers mean to us depends largely on what we bring to them. Our expectations, our past experience, the dreams and myths that surround them, their physical characteristics—all these aspects resonate on multiple, often overlapping levels.

One level is aesthetic. Many nonspecialists in the computer arts enjoy these machines for their visual appeal and curiosity. Nearly everyone, regardless of technical background, can appreciate the intricacies of a computer’s mechanical design, its rows of switches and blinking lights, its often ungainly proportions, and the personal con- nection they feel when they recognize the first computer they used.

A second level is important for specialists. People trained in computer science or electrical engineering bring the additional dimension of how these objects illuminate abstract principles of computer architecture and the ideas immanent in their design—ideas that give us insight into the minds of their designers and the challenges they faced.

A third level is the historical trajectory of these objects: how they were financed and why, what problems they were trying to solve, and the mistakes made and dead ends encountered by their designers. We learn a lot by understanding these human elements and how they shaped historical and technical factors into stable artifacts, in turn stitching together the fabric of today’s information-based society.

The Mac That Helped Build the Xbox Rides Again

See the original posting on Hackaday

The original Xbox, released in 2001 by Microsoft, was notable for being built out of largely off-the-shelf PC components. With a custom Pentium III CPU and IDE peripherals, the console was much closer to a contemporary desktop computer than any of the dedicated game consoles which had come before it. Which of course makes perfect sense if you think about it. Microsoft would want to use technology they were intimately acquainted with on their first foray into gaming market, and if there’s anything Microsoft knows better than forced system updates, it’s x86 computers.

But for their follow-up system, the Xbox …read more

Samsung’s Galaxy S10 and S10+ leaked yet again in new pictures

See the original posting on The Verge

Images supposedly showing the new upcoming Galaxy S10 and S10+

There’s less than a month to go before Samsung unveils its next flagship smartphones in San Francisco, but the devices have already been roundly leaked. The latest images come from German tech site AllAboutSamsung, and show what looked to be the Galaxy S10 and S10+ from the front, back and sides.

Not much new information is revealed in these photos, but they do offer a clearer view of the dual-lens, hole-punch camera on the S10+ (seen earlier in these photos) and what seems to be a refreshed UI. Other than that we can also see the new “Infinity-O” display, with its thin bezels and slight chin at the bottom of the device, and a familiar-looking bottom edge, complete with SIM card slot, USB-C port, and headphone jack (phew).

Vivo’s Apex 2019 is a seamless 5G phone with a ‘full-display’ fingerprint sensor and 12GB of RAM

See the original posting on The Verge

Vivo has announced the Apex 2019, the futuristic follow-up to last year’s “concept smartphone” that introduced the pop-up selfie camera later seen on the Nex. To be clear, the Apex 2019 probably isn’t ever going to ship as a real product in exactly this form, but Vivo is taking it to Mobile World Congress next month and we may well see some of its features show up in the company’s product lineup over the next year.

Like last year’s Apex, the 2019 model prioritizes screen-to-body ratio and slim bezels. It’s aggressively minimalist, without any physical buttons or port openings in sight, and features a “Super Unibody” curved glass design. Unsurprisingly there’s no headphone jack, but there isn’t even a USB-C port, either; charging is…

Kotlin Clean Code for Android, ?Part 1

See the original posting on DZone Python

Test Driven Development in Android Using Kotlin

This post is about my journey of finding the right mobile app unit testing framework and how I arrived at Kotlin Clean Code for Android. A design pattern, it is an adaptation of Android Clean Code. When you finish this blog series, I promise, you will learn how to unit test your mobile app, piece by piece.

Let Us Start With Unit Testing

Writing an Android app that has good unit test code coverage is not easy, as Android code typically has a massive activity or fragment class that manages more than one function or task. Typical fragment classes do the below tasks:

Running OpenCL on a Raspberry Pi GPU

See the original posting on Hackaday

This is an interesting development for media users and machine learning hackers: [doe300] has implemented OpenCL on the Raspberry Pi 3 Model B+called VCFCL That’s big news because the Pi 3+ has a Graphics Processing Unit (GPU) built into the processor that has been generally underutilized. The VideoCore IV GPU is built into the Broadcom BCM2837B0 and is surprisingly capable for a low-power chip. Although this GPU is well documented, it hasn’t been used that widely because you have to code specifically for this class of GPU. Adding in support for a high-level framework like OpenCL will make it much …read more

Rifle-Mounted Sensor Shows What Happens During Shot

See the original posting on Hackaday

People unfamiliar with shooting sports sometimes fail to realize the physicality of getting a bullet to go where you want it to. In the brief but finite amount of time that the bullet is accelerating down the barrel, the tiniest movement of the gun can produce enormous changes in its trajectory, and the farther away your target is, the bigger the potential error introduced by anticipating recoil or jerking the trigger.

Like many problems this one is much easier to fix with what you can quantify, which is where this DIY rifle accelerometer can come in handy. There are commercial …read more

[Leo] Repairs A MIDI Sequencer

See the original posting on Hackaday

We all have that friend who brings us their sad busted electronics. In [Leo’s] case, he had a MIDI sequencer from a musician friend. It had a dead display and the manufacturer advised that a driver IC was probably bad, even sending a replacement surface mount part.

[Leo] wasn’t convinced though. He knew that people were always pushing on the switches that were mounted on the board and he speculated that it might just be a bad solder joint. As you can see in the video below, that didn’t prove out.

The next step was to fire up a hot …read more

AWS launches WorkLink to make accessing mobile intranet sites and web apps easier

If your company uses a VPN and/or a mobile device management service to give you access to its intranet and internal web apps, then you know how annoying those are. AWS today launched a new product, Amazon WorkLink,  that promises to make this process significantly easier. WorkLink is a fully managed service that, for $5 […]

WATCH: Two New Adam Savage #MythbustersJr episodes, ‘Demolition Dominoes’ and ‘Gravity Defying Carl’

See the original posting on Boing Boing

I’ve really been enjoying the new ‘MythBusters Jr’, Adam Savage’s new science exploration show featuring… kids. Really smart awesome talented kids.

Adam Savage will be Tweeting live during tonight’s two premiere episodes, and they start airing an hour early (at 8 pm ET) for parents with wee ones.

Watch it on Science Channel through your cable/satellite provider, or SCIGO, their online streaming service.

One of the episodes tonight is ‘Demolition Dominoes.’

This small-scale test bodes well!

Here’s another show scene, with Adam helping his co-host Elijah test his concept of using bungee to remove the last Jenga piece.

Glass screen protector for our Nintendo Switch

See the original posting on Boing Boing

Glass screen protectors have saved me $100s of dollars in repairs. I use them on our cellphones, tablets and now on the Nintendo Switch my daughter and I share.

Simple to apply, these glass screen protectors ward off scratches, scuffs, and sometimes even direct hits. I never mind replacing one, as they are super cheap and the event also presents as an opportunity to clean the device needing service.

This morning our Switch was smacked into the corner of the Hammond organ my kid uses as her charging station. The value of the screen protector was proven. It shattered, the screen did not.

Motorizing An IKEA SKARSTA Table

See the original posting on Hackaday

We’ve been told that standing at a desk is good for you, but unless you’re some kind of highly advanced automaton you’re going to have to sit down eventually no matter what all those lifestyle magazines say. That’s where desks like the IKEA SKARSTA come in; they use a crank on the front to raise and lower the desk to whatever height your rapidly aging corporeal form is still capable of maintaining. All the health benefits of a standing desk, without that stinging sense of defeat when you later discover you hate it.

But who wants to turn a crank …read more

Color Sensor Demystified

See the original posting on Hackaday

When [millerman4487] bought a TCS230-based color sensor, he was expecting a bit more documentation. Since he didn’t get it, he did a little research and some experimentation and wrote it up to help the rest of us.

The TCS3200 uses an 8×8 array of photodiodes. The 64 diodes come in four groups of 16. One group has a blue filter, one has green and the other has a red filter. The final set of diodes has no filter at all. You can select which group of diodes is active at any given time.

Sixteen photodiodes have blue filters, 16 photodiodes …read more
