Assignment: Comment on using online synchronous communication as opposed to face to face communication
For the exercise we did, trying to get someone to edit our Wiki user profile page, it definitely reminds me of the stories told about the first link on the Arpanet. They had two phone lines connected between USC and I think it was Berkeley and they would type one letter in and then ask if they were seeing it on their end. Then the IMP crashed and the rebooted it, started over and eventually typed out a Hello,…
Brevity also seems to be the order of the day. Longer form kinds of things are way better suited to Wikis or Blog entries. If you can’t ask a question in a Twitter sized 140 characters or less, you might as well do an actual phone call or Skype or just email it. I guess I prefer the longer format generally when it comes to text. And as Mike Gage pointed out when you choose to do a private channel it’s essentially an IM client instead of IRC.
On the upside however is when you are there, the immediacy cannot be matched especially if you want to through the IRC client into the background. Just knowing the people are logged in is kinda like having them in the room but at different desks or even just down the hall way. That’s a way greater assurance than waiting for a Discussion Board, Newsgroup or email return message. Or a Tweet for that matter, as the latency and delay of responses is still much slower than IRC. So you gotta pick the right tool for the right job. I’ll have to really try to figure out where it fits in when I’m working on stuff.
Point taken, try to limit the use of ‘to be’ + ‘verb’ + ‘by’. I’m probably more guilty of this than most. That and the use of probably.
We've all heard the non-apology "mistakes were made." Chances are that some of us have even used it when trying to admit a mistake without quite fessing up to it. This and similar phrases are so tempting because they're indirect about whodunnit. And they're indirect because they use a little thing called the passive voice. When talking about the passive voice, people often mention that it obscures the agent, which is just a fancy way of saying it … Read More
Rumors of an ARM-based MacBook Air are not new. In May, one report claimed that Apple had built a test notebook featuring the same low-power A5 processor found in the iPad 2. The report, which came from Japan, suggested that Apple officials were impressed by the results of the experiment.
Following up on an article they did back on May 27th, and one prior to that on May 6th, AppleInsider does a bit of prediction and prognosticating about the eventual fusion of iOS and Mac OS X. What they see triggering this is an ARM chip that would be able to execute 64-bit binaries across all of the product lines (A fabled ARM A-6). How long would it take to do this consolidation and interweaving? How many combined updaters, security patches, Pro App updaters would it take to get OS X 10.7 to be ‘more’ like iOS than it is today? Software development is going to take a while and it’s not just a matter of cross-compiling to an ARM chip from a software based on Intel chips.
Given that 64-bit Intel Atom chips are already running on the new Seamircro SM10000 (x64), it won’t be long now I’m sure before the ARM equivalent ARM-15 chip hits full stride. The designers have been aiming for a 4-core ARM design that will be encompassed by the ARM-15 release real soon now (RSN). The next step after that chip is licensed and piloted, tested and put into production will be a 64-bit clean design. I’m curious to see if 64-bit will be applied across ALL the different product lines within Apple. Especially when the issue of power-usage and Thermal Design power (TDM) is considered, will 64-bit ARM chips be as battery friendly? I wonder. True Intel has jumped the 64-bit divide on the desktop with the Core 2 Duo line some time ago and made them somewhat battery friendly. But they cannot compare at all to the 10 hours+ one gets on a 32-bit ARM chip today using the iPad.
Lastly, App Developers will also need to keep their Xcode environment up to date and merge in new changes constantly up to the big cutover to ARM x64. No telling what that’s going to be like apart from the previous 2 problems I have raised here. Apple in the 10.7 Lion run-up was very late in providing the support and tools to allow the developers to get their Apps ready. I will say though that in the history of migrations in Apple’s hardware/software, they have done more of them, more successfully than any other company. So I think they will be able to pull it off no doubt, but there will be much wailing and gnashing of teeth. And hopefully we’ll see something better as the end-users of the technology, something better than a much bigger profit margin for Apple (though that seems to be the prime mover in most recent cases as Steve Jobs has done the long slow fade into obscurity).
If ARM x64 is inevitable and iOS on Everything too, then I’m hoping things don’t change so much I can’t do things similarly to the way I do them now on the desktop. Currently on OS X 10.7 I am ignoring completely:
Gestures
Misson Control
Launch Pad
AppStore (not really because I had to download Lion)
Let’s hope this roster doesn’t get even longer over time as the iOS becomes the de facto OS on all Apple Products. Because I was sure hoping the future would be brighter than this. And as AppleInsider quotes from May 6th,
“In addition to laptops, the report said that Apple would ‘presumably’ be looking to move its desktop Macs to ARM architecture as well. It characterized the transition to Apple-made chips for its line of computers as a ‘done deal’.”
The buyers include Bain Capital, the Blackstone Group, Goldman Sachs Capital Partners, Kohlberg Kravis Roberts, Providence Equity Partners and Texas Pacific Group. The group is led by Silver Lake Partners. The deal is a leveraged buyout – Sungard will be taken private and its shares removed from Wall Street.
RTTNews – Private equity firm Providence Equity Partners, Inc. agreed Friday to take educational software and systems provider Blackboard, Inc. (BBBB: News ) private for $45 per share in an all-cash deal of $1.64 billion.
It would appear now that Providence Equity Partners owns two giants in the Higher Ed outsourcing industry Sungard and Blackboard. What does this mean? Will there be consolidation where there is overlap between the two companies? Will there be attempts to steal customers or upsell each other’s products?
Google Maps gets map downloads in Labs betaAfter a brief unofficial discovery, Google on Thursday confirmed that Google Maps 5.7 has the first experimental support for local maps downloads.
Google Maps for Android is starting to show a level of maturity only seen on dedicated GPS units. True, there still is no routing feature (you need access to Google’s servers for that functionality) But you at least a downloaded map that you can zoom out and in on to get a view without incurring heavy data charges. Yes, overseas you may rack up some big charges as you navigate live maps via the Google Maps app on Android. This is now solved partially by downloading in advance the immediate area you will be visiting (within a few miles radius). It’s an incremental improvement to be sure and makes Android phones a little more self sufficient without making you regret the data charges.
Apple on the other hand is behind. Hands down they are kind of letting the 3rd party gps development go to folks like Navigon and TomTom who both require somewhat hefty fees to license their downloaded content. Apple’s Maps doesn’t compare to Navigon, TomTom, much less Google for actual usefulness in a wide range of situations. And Apple isn’t currently using the downloadable vector based maps introduced with this revision of Google Maps for Android vers. 5.7. So it will struggle with large jpeg images as you pan and scan around the map to find your location.
An original SM10000 server with 512 cores and 1TB of main memory cost $139,000. The bump up to the 64-bit Atom N570 for 512 cores and the same 1TB of memory boosted the price to $165,000. A 768-core, 1.5TB machine using the new 64HD cards will run you $237,000. Thats 50 per cent more oomph and memory for 43.6 per cent more money. ®
SeaMicro continues to pump out the jams releasing another updated chassis in less than a year. There is now a grand total of 768 processor cores jammed in that 10U high box. Which leads me to believe they have just eclipsed the compute per rack unit of the Tilera and Calxeda massively parallel cloud servers in a box. But that would wrong because Calxeda is making a 2U server rack unit hold 120-4 core ARM cpus. So that gives you a grand total of 480 in just 2 rack units alone. Multiply that by 5 and you get 2400 cores in a 10U rack serving. So advantage Calxeda in total core count, however lets also consider software too. Atom being the cpu that Seamicro has chosen all along is an intel architecture chip and an x64 architecture at that. It is the best of both worlds for anyone who already had a big investment in Intel binary compatible OSes and applications. It is most often the software and it’s legacy pieces that drive the choice of which processor goes into your data cloud.
Anyone who had clean slate to start from might be able to choose between Calxeda versus Seamicro for their applications and infrastructure. And if density/thermal design point per rack unit is very important Calxeda too will suit your needs I would think. But who knows? Maybe your workflow isn’t as massively parallel as a Calxeda server and you might have a much lower implementation threshold getting started on an Intel system, so again advantage Seamicro. A real industry analyst would look at these two competing companies as complimentary, different architectures for different workflows.
Great set of comments along with a very good description of advantages of using NoSQL in a web application. There seems to be quite a bit of philosophical differences over whether or not NoSQL needs to be chosen at the earliest stages of ANY project. But Jeremy’s comments more or less prove, you pick the right tool for the right job, ‘Nuff Said.
Jeremy Zawodny: I found myself reading NoSQL is a Premature Optimization a few minutes ago and threw up in my mouth a little. That article is so far off base that I’m not even sure where to start, so I guess I’ll go in order. In fact, I would argue that starting with NoSQL because you think you might someday have enough traffic and scale to warrant it is a premature optimization, and as such, should be avoided by smaller and even medium sized organizations.

Just a very brief look at a couple of patent filings by Apple with some descriptions of potential applications. They seem to want to use it for navigation purposes using the onboard video camera. One half the screen will use the live video feed, the other half is a ‘virtual’ rendition of that scene in 3D to allow you to find a path or maybe a parking space in between all those buildings.
The second filing mentions a see-through screen whose opacity can be regulated by the user. The information display will take precedence over the image seen through the LCD panel. It will default to totally opaque using no voltage whatsoever (In Plane switching design for the LCD).
However the most intriguing part of the story as told by AppleInsider is the use of sensors on the device to determine angle, direction, bearing to then send over the network. Why the network? Well the whole rendering of the 3D scene as described in first patent filing is done somewhere in the cloud and spit back to the iOS device. No onboard 3D rendering needed or at least not at that level of detail. Maybe those datacenters in North Carolina are really cloud based 3D rendering farms?
While everyone in the IT racket is trying to figure out how many Intel Xeon and Atom chips can be replaced by ARM processors, Steve Furber, the main designer of the 32-bit ARM RISC processor at Acorn in the 1980s and now the ICL professor of engineering at the University of Manchester, is asking a different question, and that is: how many neurons can an ARM chip simulate?
The phrase reminds me a bit of an old TV commercial that would air during the Saturday cartoons. Tootsie Roll brand lollipops had a center made out of Tootsie Roll. The challenge was to determine how many licks does it take to get to the center of a Tootsie Roll Pop? The answer was, “The World May Never Know”. And so it goes for the simulations large scale and otherwise of the human brain.
I remember also reading Stewart Brand’s 1985 book about the MIT Media Lab and their installation of a brand new multi-processor super computer called The Connection Machine (TCM). Danny Hillis was the designer and author of the original concept of stringing together a series of small one bit computer cores to act like ‘neurons’ in a larger array of cpus. The scale was designed to top out at around 65,535 (2^16). At the time MIT Media Lab only had the machine filled up 1/4 of the way but was attempting to do useful work with it at that size. Hillis spun out of MIT to create a startup company called Thinking Machines (to reflect the neuron style architecture he had pursued as a grad student). In fact all of Hillis’s ideas stemmed from his research that led up to the original Connection Machine Mark. 1.
Spring forward to today and the sudden appearance of massively parallel, low-power servers like Calxeda using ARM chips, Qanta Sq-2 using Tilera chips (also an MIT spin out). Similarly the Seamicro SM-10000×64 which uses Intel Atom chips in large scale, large quantity. And Seamicro is making sales TODAY. It almost seems like a stereotypical case of an idea being way ahead of its time. So recognize the opportunity because now the person directly responsible for designing the ARM chip is attacking that same problem Danny Hillis was all those years ago.
Personally I would like to see Hillis join in some way with this program not as Principal Investigator but may a background consultant. Nothing wrong with a few more eyes on the preliminary designs. Especially with Hillis’s background in programming those old mega-scale computers. That is the true black art of trying to do a brain simulator on this scale. Steve Furber might just be able to make lightning strike twice (once for Acorn/ARM cpus and once more for simulating the brain in silicon).
I too am a big believer in RSS. And while I am dipping toes into Facebook and Twitter the bulk of my consumption goes into the big Blogroll I’ve amassed and refined going back to Radio Userland days in 2002.
When I left the pageview business I walked away from an engine that had, for many years, manufactured an audience for my writing. Four years on I’m still adjusting to the change. I always used to cringe when publishers talked about using content to drive traffic. Of course when the traffic was being herded my way I loved the attention. And when it wasn’t I felt — still feel — its absence. There are plenty of things I don’t miss, though. Among t … Read More
