Wrapping Up a Apple Location Brouhaha

Well, for softened or worse, Locationgate is over.

As we might recall, final week, a span of researchers pronounced that they’d found a tip record in a hard-drive backup of each iPhone and mobile iPad. This file, they said, contained a time-stamped list of everywhere you’d been with your phone given final Jun (or whenever we commissioned iOS 4).

There was no indication, they said, that this information was being transmitted to Apple, a government, or a Warren Commission; it was usually sitting there on your tough drive, permitted usually with Unix commands (or with an app that a researchers wrote). But even so, swindling theorists immediately went into hysterics.

On Wednesday, Apple responded with a statement explaining a participation of a file. “Apple is not tracking a plcae of your iPhone,” it said. “Apple has never finished so and has no skeleton to ever do so.”

The matter goes on to say: “The iPhone is not logging your location. Rather, it’s progressing a database of Wi-Fi prohibited spots and dungeon towers around your stream location, some of that might be located some-more than one hundred miles divided from your iPhone, to assistance your iPhone quick and accurately calculate a plcae when requested. Calculating a phone’s plcae regulating usually GPS satellite information can take adult to several minutes. iPhone can revoke this time to usually a few seconds by regulating Wi-Fi prohibited mark and dungeon building information to quick find GPS satellites, and even triangulate a plcae regulating usually Wi-Fi prohibited mark and dungeon building information when GPS is not accessible (such as indoors or in basements). These calculations are achieved live on a iPhone regulating a crowd-sourced database of Wi-Fi prohibited mark and dungeon building information that is generated by tens of millions of iPhones promulgation a geo-tagged locations of circuitously Wi-Fi prohibited spots and dungeon towers in an unknown and encrypted form to Apple.”

So basically, Apple is observant that a researchers were wrong on both counts. First, a “secret file” contains information about circuitously Wi-Fi prohibited spots and dungeon towers, not your accurate location. And second, your device is promulgation information to Apple, nonetheless in an anonymous, encrypted form.

Now, one partial of Apple’s response is a small unconvincing. Yeah, O.K., a record includes a plcae of Wi-Fi prohibited spots and dungeon towers — nearby you. So no, it doesn’t record what park dais we were sitting on. But it’s still tracking what city we were in, and is therefore gripping a record of your travels.

Last week, formed on a information accessible during a time, we wrote about because we didn’t consider this was such a large deal. First, you’re a usually one with a entrance to your iTunes backup, and presumably we already know where you’ve been. Second, there are so, so many other ways your remoteness is compromised these days, some most some-more obligatory than this. (How come, for example, nobody’s in hysterics over a 77 million names, e-mail addresses, passwords and presumably credit label numbers that Sony says were swiped from a PlayStation database?)

I’m always confused by a hypotheticals that people with a Conspiracy Gene come adult with. Dozens of we wrote me to say, “Before we boot a remoteness concerns out of hand, what about an violent ex-spouse?”

That’s totally illogical. First, what good does it do a ex-husband to know where you’ve been before your final iTunes backup? He can’t accurately go behind to final month and apply we there.

But even some-more important, to find out where you’ve been, a ex would have to be in your house, during your computer. And listen: if your violent ex is inside your house, sitting during your computer, we have most bigger problems than a iTunes backup. What we need isn’t a opposite phone — it’s a locksmith.

Anyway, a whole thing is indecisive now. In a program refurbish in a subsequent integrate of weeks, Apple will (a) stop subsidy adult a plcae database to your computer, (b) store usually a week’s value of prohibited mark locations and (c) stop collecting prohibited mark locations if we spin off Location Services.

(“The reason a iPhone stores so most information is a bug we unclosed and devise to repair shortly,” Apple says, not wholly believably. “We don’t consider a iPhone needs to store some-more than 7 days of this data.” You can review some-more about a response, including a Times talk with Steve Jobs, here.)

In a subsequent iOS update, furthermore, a plcae list will also be encrypted on a phone itself.
Interestingly, Apple also achieved a pre-emptive strike. It suggested something else your iPhone is tracking: trade information (presumably measuring how quick your iPhone is relocating when it’s on roadways). “Apple is now collecting unknown trade information to build a crowd-sourced trade database with a idea of providing iPhone users an softened trade use in a subsequent integrate of years.” That’d be cool.

This is a second time Apple has found itself neck-deep in a P.R. brouhaha where it blamed a problem on a bug. Remember a Death Grip issue, where a iPhone 4 would remove vigilance bars if your palm lonesome a reduce left corner? And how Apple pronounced that a problem was, in part, a bug in how a phone counted a series of bars to arrangement on a screen?

Both times, Apple wasn’t apologetic, though during slightest it took prompt movement by a program update. In this case, during least, confidence consultants seem satisfied. Apparently, a Locationgate box is now closed.

Now then. About those PlayStation credit cards…

Global OS income strike $30.3B in 2010

Worldwide handling complement (OS) income grew to US$30.3 billion final year, clocking an boost of 7.8 percent from 2009, according to new total from Gartner.

Pointing to a liberation of a tellurian economy as a poignant cause in a market’s healthy showing, a investigate organisation combined that customer platforms grew faster than a server segment, flourishing 9.3 percent final year compared to 5.7 percent for server OSes.

Matthew Cheung, Gartner’s principal investigate analyst, pronounced in a report: “The long-pending direct for PC snack was unleashed as a economy stepped out from a mercantile turndown, that gathering expansion of customer OSes.”

Within this OS segment, Apple’s Mac OS saw a fastest expansion as a laptops and desktops saw clever sales, nonetheless from a most smaller base. Microsoft’s Windows customer remained a largest customer OS segment, induction a high single-digit expansion that was quite driven by a adoption of Windows 7 and a termination of Windows XP.

In fact, Microsoft’s Windows customer income saw aloft expansion during 9.2 percent, compared to a Windows server business that grew 7.5 percent.

In a server OS segment, Linux valid a fastest-growing sub-segment as end-users embraced some-more open standards systems,

Linux’s server was a fastest-growing sub-segment in 2010 since finish users embraced some-more open-standard systems, explained Alan Dayley, handling clamp boss during Gartner. Within a Unix OS market, he remarkable that IBM AIX clocked high single-digit expansion though Unix gifted “modest or disastrous growth”.

“The end-of-life hazard for Unix OSes such as Tru64 and NetWare pushed a ‘other exclusive Unix’ sub-segment down 39.6 percent in 2010, as some vendors late their exclusive Unix and changed users to some-more open systems,” Dayley said.

According to Gartner, Red Hat continued to browbeat a blurb Linux server marketplace where a vendor’s Red Hat Enterprise Linux server permit climbed 18.6 percent to US$592 million final year. The height accounted for 58.2 percent of a altogether Linux server market.

Worldwide, a altogether OS marketplace was dominated by Microsoft that accounted for 78.6 percent of altogether revenue, an 8.8 percent boost from 2009, Gartner revealed. It combined that a program hulk confirmed a stick position with income totaling US$23.8 billion final year, compared to US$21.9 billion in 2009.

IBM and Hewlett-Packard ranked in second and third, respectively. Big Blue grew a income by 5.6 percent to US$2.2 billion final year with a 7.5 percent marketplace share, a slight drop from 7.7 percent in 2009. HP clocked a 1.4 percent income expansion to US$1.1 billion final year with a 3.7 percent marketplace share, down from 3.9 percent in 2009.

Oracle and Red Hat dull adult a worldwide Top 5 OS businessman during 4th and 5th positions, respectively, with a marketplace share of 2.6 percent and 2 percent.

Apple ranked 6th with a marketplace share of 1.7 percent.

C/C++ Programming in a UNIX Environment

Edsger W. Dijkstra wrote an successful paper behind in 1988 called On a cruelty of unequivocally training computing science, that advocated an proceed strongly grounded in a investigate of grave systems.

While we would be a initial to acknowledge that we am not fit to lift a late Dr.’s punch cards, we would contend that if he unequivocally wanted to see cruelty, he competence have attempted his palm during a undergraduate march we taught this semester: C/C++ Programming in a UNIX Environment. This category was cruelty personified.

How prolonged did it take we to learn C++? Do we consider we could fist that into a singular undergraduate semester, giving it usually a 20% of your courtesy camber that is due?

Now chuck into a brew a requirement that we have to learn C as well.

And to keep things interesting, all your work has to be finished on a UNIX or Linux machine. You’ve used Windows given we were 8, and consider that cat is a four-legged pet and grep is some arrange of gastrointestinal complaint.

Yep, we are in trouble.

Tricky Assignments

The good news in all this was that we didn’t make any of Andrew Koenig’s gross errors when training a class. The bad news is that each task assignment we combined looked to my students like dual insurmountable towering ranges instead of one: an unintelligible C++ problem to be implemented on an complicated O/S, regulating an IDE that was decidedly not Visual Studio.

Just as an example, for a new assignment, we had a category comfortable adult with a pristine C++ doing of mergesort, reading a fibre of difference from customary submit and essay a sorted list to customary output. Using all a comforts during palm in a C++ customary library meant that a mergesort doing was a zephyr — about a usually square of a algorithm that compulsory most suspicion was merging a dual subcontainers after dividing and conquering.

After a warmup partial of a assignment came a meatier portion: we asked a students to exercise a mergesort algorithm by flitting a subproblems to child processes. This meant they indispensable to solve a few really common problems encountered when programming on *IX:

  • Using fork() to emanate child processes

  • Managing a lifetime of primogenitor and child processes

  • Managing unnamed pipes for communication between a primogenitor and child process

  • Serializing and deserializing C++ containers so they can be transmitted by a de-objectifying pipe

Admittedly, this is not a ideal proof of a approach to parcel a problem out mixed processes. In fact, if finished regulating a candid doing of a problem, we can emanate a pleasing instance of a fork bomb, bringing your complement to a knees. But we suspicion it would be a good approach to get a hang of operative with child processes in a rather picturesque way. (And this could indeed be a good approach to discharge a classification routine — if we usually split a singular series of times during a tip of a merge.)

By rowdiness around a bit with routine names, we was even means to do a bad man’s animation of a routine regulating pstree.

When we worked adult a assignment, it seemed like a reasonable assignment to tackle over a march of a week. Alas, during a one-week deadline, my inbox was empty.

Lessons Learned

This wasn’t a initial assignment that incited out to be a semi-disaster. My Scrabble diversion house manager saw a identical fate, as did my Scrabble word generator assignment.

As part-time non-tenure lane faculty, we don’t have a lot of contend in curriculum development. But after going by this course, we will really be flitting along a clever recommendation: If we are going to ask students to learn a new denunciation regulating new collection with a new O/S, we need to cgange a category structure so that during slightest half of a hours are spent in a lab.

When we worked by these problems in a lab environment, it was easy to yield a peaceful poke to assistance someone who was stranded perplexing to get Eclipse or NetBeans to do a expected, instead of whatever impolite trail they were on. we could assistance with a C++ compiler errors, that over a decade after standardization are still a travesty. And we could assistance awaken a debugger into providing serviceable information when looking during customary C++ objects — that a IDEs will do usually grudgingly. In other words, assistance with a undocumented tips and tricks that gifted C++ programmers take for granted.

At a finish of a semester, we do feel flattering good about a class’s poise of C++ ‚Äî they dripping adult as most of this outrageous denunciation as was humanly possible. UNIX/Linux imagination didn’t seem to get a same turn of joining ‚Äî that is hapless though understandable.

Learning C and C++ in a same category can be a bit tricky. While C is scarcely a correct subset of C++, a libraries are radically different, and only training how to use a C subset of a denunciation is not enough. But training C++ is so time-consuming that it is easy to shortchange a C side of a curriculum.

‚Ä®‚Ä®Of course, there are copiousness of C++ haters out there, and they will intent to a fact that C++ is even partial of a march name. If we trust people like Linus, simply expressing a welfare for C++ means we are not able of producing decent products. But that’s a subject for another post.

Novell Sale to Attachmate Completed

Today is a final day that Novell (NASDAQ:NOVL) will exist as a publicly traded company. Trading in Novell’s batch will stop during a tighten of business, as a association is taken private.

Novell is being acquired by secretly hold Attachmate in a understanding that closes today. The $2.2 billion acquisition was initial announced in Nov of 2010.

Attachmate is profitable $6.10 per Novell share and will keep Novell as a unconditionally owned subsidiary. Novell shareholders approved a understanding behind in February. The final step that was compulsory for a understanding to pierce brazen was a execution of a obvious deal.

As partial of a Attachmate acquisition, Novell is offered 882 patents to a organisation called CTPN Holdings for $450 million. CPTN is a organisation that includes Microsoft, Apple and EMC. The obvious sales was contested by open source advocates as good as authorities in Europe. The fear was that Novell’s open source patents could be used to conflict open source vendors.

The other regard was about what would occur to Novell’s UNIX copyrights, that were a theme of a justice conflict with SCO. Novell has publicly settled that Attachmate would be holding onto a UNIX copyrights.

Thanks to a U.S. Department of Justice (DoJ), Attachmate will be holding onto a lot some-more than only UNIX. The DoJ adjusted a CPTN obvious sale in a pierce designed to forestall attacks opposite a open source ecosystem.

As partial of a practiced deal, Microsoft will be offered behind to Attachmate all of a Novell patents that Microsoft would have differently acquired. Attachmate in spin will continue to accept a permit for a use of a Novell patents.

“Novell has had many chapters in a 28-year story and currently outlines a start of a new, sparkling chapter,” John Dragoon, a Chief Marketing Office during Novell blogged. “As Novell joins army with The Attachmate Group, a outcome will be a absolute portfolio of companies joined by a common purpose and dedicated team.”

More than one approach to build a cloud (and there always will be)

The open systems series of a late 1980s and early 1990s, that espoused interoperability between platforms, finished a several Unix handling systems a world’s many renouned server platforms.

If we cruise Linux a kind of Unix, afterwards we can disagree that nonetheless Windows has widespread into tiny and middle businesses, a Unix height still dominates a craving server landscape.

The honesty in Unix and Linux has helped these systems say their position in a market, even yet Windows has an sequence of bulk some-more program developers.

People do learn. When any new record comes down a line, interjection to a healthy effects of a open-systems approach, there is shortly a call for standards and interoperability by common APIs and open source code.

The open call is now being finished for a smarts behind computing clouds – what are mostly called cloud fabrics or cloud controllers.

These are a trade cops determining how hypervisors and practical machines are dismissed adult and close down on a clusters of servers that are connected together as a hulk pool of CPU capacity.

Cloud fabrics are a über handling complement – and a high belligerent from that pivotal program suppliers will try to browbeat a virtualisation field. And that means, notwithstanding all a speak of team-work and openness, vendors will be tempted to make their platforms improved and say some incompatibilities.

We’re in a money

VMware, a server virtualisation attention juggernaut, took an early lead with a ESX bare-metal hypervisor. Although VMware likes to fake that many of a components in a vSphere smoke-stack of server virtualisation collection are add-ons to a hypervisor, many of a modernized functions, such as live migration, backup, failover and other practical appurtenance features, are coded in a hypervisor and accessed by a vCenter console.

The company’s vCloud Director, on a other hand, is a cloud fabric. It wraps around mixed instances of ESX hypervisors and vCenter controllers and adds ability management, metering and adaptation functions, as good as a self-service portal.

This final is pivotal since it allows end-users to ask computing, storage and networking resources from a IT dialect in a unchanging manner, and enables a IT dialect to broach it in a unchanging manner.

It is a sealed complement usually as most as Windows is

Importantly for VMware, vCloud Director manages usually ESX practical machines. It is a sealed complement usually as most as Windows is.

There’s some large income to be finished here. The initial recover of vCloud Director spans adult to 25 vCenter consoles and adult to 10,000 concurrent-running practical machines. vCloud Director costs $150 (£90) per practical appurtenance underneath government when it is used with a vSphere stack.

The Request Manager portal costs another $100 (£60) per practical appurtenance and a Capacity IQ ability planner costs an additional $75 (£45) per practical machine. On a cloud with 10,000 practical machines, The vSphere Enterprise Plus hypervisor and vCenter consoles would cost $3.8m( £2.3m) during list price, and a vCloud extensions would cost another $3.25m (£2m). This is not sparse change: any square – hypervisor and cloud fabric – away rivals a cost of large two-socket servers underlying a cloud, that competence cost somewhere around $3.5m (£2.1m) for a 450 machines creation adult that cloud.

Jaunty Red Hat

Unsurprisingly, a open-source village sees this kind of lock-in and those kind of prices, and declares it has a improved idea.

Commercial Linux distributor Red Hat, that has finished a best pursuit of branch a open-source Linux and Java middleware stacks into a flourishing and essential business, ate Qumranet a few years ago to benefit control of a KVM (kernel-based practical machine) hypervisor.

With a RHEL Enterprise Linux 6 handling complement announced final autumn, a KVM hypervisor is prepared for primetime and has been extended with a possess cloud fabric, that Red Hat calls a Cloud Foundations stack.

Red Hat is putting onward a possess KVM and associated collection as all that is indispensable to emanate a cloud. But a association is also articulate adult a Deltacloud government APIs, and earnest interoperability with private clouds formed on VMware’s ESX or Microsoft’s Hyper-V, as good as open clouds combined by Amazon, IBM and others.

Red Hat does not yield a cost for a cloud stack, yet presumably if we buy adequate hypervisors and support contracts, it will be reduce than what VMware is perplexing to charge.

Quality fabric

Eucalyptus Systems, that combined a mostly open-source cloud fabric that emulated Amazon’s EC2 cloud regulating a homegrown Xen hypervisor, looked like it competence be a cloud fabrics personality to opposition VMware. With Canonical embedding Eucalyptus in a possess Ubuntu Enterprise Cloud, it positively looked that way.

But afterwards NASA and Rackspace Hosting motionless to work together with a who’s who list of IT vendors to make a cloud fabric that is totally open source. That software, called OpenStack, is elaborating fast, has a lot of appetite behind it, and aims to emanate a cloud that can camber one million horde servers and control adult to 60 million practical machines during once.

And if story is anything to go by, blurb support for OpenStack will be a lot cheaper than VMware’s vCloud Director, once companies start charity support services for it a approach Red Hat and Canonical do for Linux. In fact, it substantially won’t be prolonged before both Red Hat and Canonical adopt OpenStack as their cloud controllers of choice.

Don’t design VMware or Microsoft to follow fit any time soon, though. ¬Æ

Oracle Agenda Shows Advantage Over Competition

In a new survey, Gabriel Consulting Group got responses from 450 craving business with opinions on Oracle (NSDQ:ORCL)¬ís preference to dump growth of a program for a Intel (NSDQ:INTC) Itanium processor platform, and by prolongation Hewlett-Packard (NYSE:HPQ)’s HP-UX Unix platform. Respondents, according to CRN, see a preference as partial of an desirous bulletin to put a server competitors during a waste and give a possess server line a advantage.

“¬íSo business really see an bulletin here on Oracle’s partial that this isn’t business as usual, though instead is a step in a strategy,¬í he said. ¬ëAnd this is not indispensably a initial step. I’ve seen some business contend that changes in Oracle’s pricing per processor is directed during putting their servers during an advantage, or others’ servers during a disadvantage.¬í”
