Connections enjoying float with Unix Hanover

Freehold, NJ — Scott Blackler had a flattering good day on a golf march one new tumble afternoon and it had zero to do with a approach he played. Blackler, a strap racing tutor formed in Middletown, N.Y., went out to fire a spin with a crony and finished adult with a horse. That equine — a now 4-year-old pacer Unix Hanover — has won 5 of 8 races given fasten Blackler’s fast and is being forked toward March’s Sagamore Hill Series during Yonkers Raceway.

It all started with a phone call from Blackler’s crony Marc Reynolds, a equine representative from Maine, as Blackler was removing prepared to tee off. Reynolds told Blackler, a Maine native, that a equine in Ontario named Unix Hanover was available, though Reynolds indispensable to know either Blackler wanted a equine within an hour.

Blackler fast contacted owners Bill Ethier and told him about a opportunity. Ethier watched a replay of one of a horse’s races and favourite a tact and gave a go forward for a purchase.

“I’ve always favourite horses that can work their approach adult a (conditions) ladder during Yonkers,” Blackler said, referring to Unix Hanover carrying usually dual wins and $10,572 on his label during a time of a Oct. 9 sale. “It’s tough to find those horses. we trust (Reynolds) utterly a bit. He told me he was a clean-legged horse; there was zero wrong with him. Murray Brethour had a equine in Canada and he likes to spin over anything branch (age) 4. It worked out for us.”

Unix Hanover is a son of stallion Yankee Cruiser out of a Western Hanover mare Up Front Rose. Unix Hanover sole for $40,000 as a deer and is a half-brother to Union Man Hanover, who won a 2011 New York Sire Stakes Fall Harvest championship during Yonkers.

“(Ethier) always wanted a Yankee Cruiser (offspring) and he loves Western Hanover,” Blackler said. “He motionless to burst right in on it.

“The initial time we jogged a equine we couldn’t trust it. He’s a attractive equine and he’s a pleasure on a track. He always feels good, in fact he acts like a colt still. He’s not that formidable to take caring of, really. He jogs, he trains, and we go to a races.”

Unix Hanover has done all 8 of his starts for his new connectors during Yonkers’ half-mile oval. He finished seventh from post 8 in his entrance for his new barn, though has finished worse than second usually once given then.

“We didn’t unequivocally change most on him,” Blackler said. “He’s drawn good and all has usually worked out. He gets around a half so well, that is because we haven’t taken him to a Meadowlands. We have him lined adult for a Sagamore. We’ll see what happens.”

Blackler, who has 12 horses during Mark Ford’s training core in upstate New York, hopes to also send Secret Delight and another new acquisition, Santanna Star, to a Sagamore Hill Series. Of that group, Unix Hanover is a usually one to have raced so distant this deteriorate — winning in 1:57 on Jan. 12.

“He’s talented,” Blackler said. “Wherever it takes him, it takes him. we don’t know what he could be. Could he be a 4-year-old open horse, could he be a Sagamore champion, we don’t know. But he’s tough when he gets to a front. He doesn’t let horses go by him when he gets to a front.”

The 77-year-old Ethier, who lives in Delaware and owns Unix Hanover with his mother Barbara, has incited down several offers for a pacer.

“He says he’s never had a equine like him, so he’s not for sale,” Blackler said. “They suffer it. They transport to a races. They gathering 5 hours to Yonkers to watch him race. They adore to watch their horses.”

And so distant Unix Hanover has done those trips — not to discuss holding phone calls on a golf march — some-more than worthwhile.

Happy 1.5 Billion Unix Seconds

On Jan. 1, 1970, Unix time was born. It didn’t indeed exist on that day; a Unix handling complement usually kind of/sort of existed afterwards anyhow. But when a initial book of a Unix primer was expelled in 1971, it was so announced that a commencement of Unix time—the Unix epoch, correctly—hath began on New Year’s Day, 1970.

Maybe you’ve listened of a Unix epoch. Simply, it’s a anxiety date that Unix-based computers use to tell time. It is usually a count of a series of seconds that have elapsed given a commencement of a epoch. If you’re using a Unix or Unix-like machine, we can get this count in a tender form by entering “date +%s” during a authority line/terminal. (“Date” by itself will usually give we a tedious aged date-date.) As of this writing, we’re during 1,451,688,846 seconds.

And now 1,451,689,116 seconds. We’re removing close.

It’s a elementary system. Every day a new 86,400 seconds spin over. The Unix time complement is dubious about things like a day of a week, a month, a hour, or unequivocally any of a accoutrements of tellurian timekeeping. The Unix time is dubious about Earth’s circuit around a Sun, and Earth’s revolution about a axis. It’s usually a counter.

The downside is that Unix time doesn’t comment for jump seconds, that are a effect of Earth’s revolution not being utterly on a money, e.g. not holding accurately 86,400 seconds to make one full spin. It competence take an additional few milliseconds here and there since it’s a good big-ass world and doesn’t caring most about a timekeeping methods.

Leap seconds are slipped into Unix time usually really rarely. The time competence parasite usually once for dual seconds, or it competence not parasite during all for a singular second. Nothing is ever combined or subtracted from it, that is a complement that keeps a lot of things from breaking.

Speaking of breaking, Unix time runs into a problem during 03:14:07 UTC on 19 Jan 2038. The 2038 epochalypse will start when a Unix time opposite overflows a boundary of a 32-bit integer information form (at 2,147,483,647 seconds). Time will usually rollover to 0 and start again.

Upgrading a date complement from a 32-bit formats to a 64-bit format won’t be easy, generally given how many embedded (“Internet of Things”) inclination are approaching to be around by then. Sneaking an unupgraded date format by in a courage of a smart-dishwasher is a whole lot easier to suppose than an iPad or laptop. But we also don’t have most of a choice.

’46 years’ Facebook glitch is a New Year’s present from Unix

A association orator told Bloomberg that a group is now regulating a bug “so everybody can ring in 2016 feeling immature again” yet didn’t teach on what it is. According to some mechanism experts such as Microsoft Developer Mark Davis, though, a law-breaker is many expected a Unix handling complement used by many information centers.

Unix’s inner calendar has an arbitrarily reserved starting indicate called “epoch” with an inner value of “0.” The OS calculates for time by counting seconds from that day. Guess what date this starting indicate is — that’s right, it’s Jan 1st, 1970, that is 46 years ago today.

Davis wrote on Facebook:

…if we click on your “Memories page, you’ll see a subset of your friends listed as carrying a 46-year-old Facebook memory today. Scrolling by my list, it’s indeed people I’ve been friends with on Facebook for a really prolonged time — chances are, a “Friends with since” underline was implemented AFTER we became friends with those people. And as such, it’s stored in a database as “0” rather than a tangible date.

He combined that a developers who wrote a underline should have enclosed a line in their codes that indoctrinate it not to use a “0” value as a “Friends with since” starting date. This Unix glitch, by a way, is utterly common, and it’s not surprising for gadgets’ clocks and calendars to switch to Dec 31st, 1969. We doubt you’d wish to spend a initial day of 2016 articulate about Unix, yet hey, during slightest we don’t have to do your investigate in a center of your family’s New Year celebration when your grandparents ask.

‘Xinu is not Unix’

XINU stands for Xinu Is Not Unix — nonetheless it shares concepts and even names with Unix, a inner pattern differs completely. Xinu is a small, superb handling complement that supports energetic routine creation, energetic memory allocation, network communication, internal and remote record systems, a shell, and device-independent I/O functions. The tiny distance creates Xinu suitable for embedded environments.

SSH Key Conversion to an OpenSSH compatible format

puttygen supports exporting your private key to an OpenSSH compatible format. You can then use OpenSSH tools to recreate the public key.

Open PuttyGen
Click Load
Load your private key
Go to Conversions->Export OpenSSH and export your private key
Copy your private key to ~/.ssh/id_dsa (or id_rsa).
Create the RFC 4716 version of the public key using ssh-keygen

Failed Windows 3.1 complement blamed for shutting down Paris airport


Paris Orly airfield had to tighten temporarily last Saturday after a disaster of a complement using Windows 3.1—yes, a handling complement from 1992—left it incompetent to work in fog.

French satirical weekly Le Canard Enchaîné reported a failure, and Vice stretched on a claims.

Orly uses a complement called DECOR to promulgate Runway Visual Range (RVR) information to pilots. In bad continue conditions—such as a haze a airfield gifted on Saturday—this complement is essential. Last Saturday it stopped working, and a airfield struggled to figure out why.

This use of ancient systems is apparently not unusual. Vice quotes Alexandre Fiacre, a secretary ubiquitous of France’s UNSA-IESSA atmosphere trade controller union, as observant that “The collection used by Aéroports de Paris controllers run on 4 opposite handling systems, that are all between 10 and 20 years old,” with Windows 3.1 being assimilated by Windows XP and vague UNIX systems. Fiacre says that a systems are feeble confirmed as well. Moreover, a age of these systems means that it’s tough to find staff who can work with them, with Fiacre explaining, “We are starting to remove a imagination [to deal] with that form of handling system. In Paris, we have usually 3 specialists who can understanding with DECOR-related issues.” And this problem is removing worse as “One of them is timid subsequent year, and we haven’t found anyone to reinstate him.”

Le Canard Enchaîné writes that according to France’s ride minister, airfield systems will be upgraded by 2017. Fiacre, however, is unconvinced, observant it will be “2019 during a earliest, maybe even in 2021.”

Whenever a ascent does happen, they competence even switch to something done this century.

2015 misfortune year in story for Mac malware

While Mac users have enjoyed a computing knowledge mostly giveaway of viruses and trojans, a final year has seen a branch indicate in fortunes.

According to a new report, 2015 has seen some-more malware targeting Apple desktops and servers than a final 5 years in total. The report, published by IT confidence organisation Bit9 + Carbon Black Threat Research team, analysed some-more than 1,400 singular OS X malware samples and found a inundate of malware attacks this year.

“As big-picture trends from a information began to emerge, one information indicate struck a group as quite noteworthy: 2015 has been a many inclusive year in story for OS X malware,” a investigate group pronounced in a report. “In 2015 alone, a investigate found, a series of OS X malware samples has been 5 times larger than in 2010, 2011, 2012, 2013 and 2014 combined.”

The news cited a flourishing recognition of Macs as an choice to Windows as one reason behind a boost in malware targeting a handling system. More than ever before, Macs have entered a workplace that hackers could conflict anticipating to benefit entrance to supportive data.

“This arise in Mac OS X malware comes after several years of fast OS X marketplace share gains, with 16.4 percent of a marketplace now using OS X, including expanding deployment in a enterprise,” a news said. “This represents a flourishing conflict aspect for supportive data, as 45 percent of companies now offer Macs as an choice to their employees.”

Some of a many common malware targeting OS X were: Lamadai, a backdoor trojan targeting a Java vulnerability; LaoShu, spam around undelivered mail parcels; Appetite, a trojan targeting supervision organisations; and Coin Thief, that stole bitcoin login certification around a hacked chronicle of a Angry Birds game.

The firm’s research showed that many OS X malware used facilities of a OS such as LaunchDaemons/ LaunchAgents, login equipment and browser plugins.

“Malware some-more mostly resided in userland and leveraged diligence mechanisms that upheld this as against to attempting to reside in kernel-land by essay tradition heart extensions,” a news said.

It pronounced another turn in a research was that a group approaching that, given OS X’s roots in FreeBSD, bettering Unix/Linux malware would be common.

“However, formed on this 10-week analysis, there does not seem to be much, if any, Unix-style malware brought over to OS X,” it said.

The news combined that Apple introduced a new bucket authority in OS X10.8, though 90 percent of OS X malware still used a aged method, that done a malware most easier to spot. “Malware authors are not updating their malware to heed to a latest specifications by Apple.”

The news pronounced that given OS X has until recently been mostly abandoned by malware and usually frequency a aim of modernized cyber-attacks, many enterprises have unsuccessful to exercise a same safeguards and controls on OS X inclination as they have for Windows machines. 

“As OS X malware and targeted attacks have increased, this confidence opening has left many organisations unprotected and incompetent to brand or stop infections. This existence has been compounded by a miss of OS X support from many endpoint confidence vendors and is a vital disadvantage for organisations with vast OS X deployments,” a news said.

Atmel’s SAMD2 Series Looks Like Any MCU, but…

by Jim Turley

Ho-hum, another ARM-based microcontroller. Not unequivocally news, right? But each once in a while we get astounded in this business.

Today we got astounded by Atmel and a new SAMA5D2 array of MCU chips. At first, they sounded like any other low-cost family of MCUs – and, in a lot of ways, they are. They’re formed on a renouned ARM Cortex-A5 CPU core; they have on-chip marginal controllers; they come in a few opposite packages; and prices start during $4.95 in decent volumes.

But one engaging factoid jumped out during me. Atmel offers a choice of handling systems for these new chips, including ThreadX, FreeRTOS, NuttX, and Linux. Hang on – what? Linux on a $5 microcontroller? What is a universe entrance to?

Some of we are aged adequate to remember when Linux initial came out. It was a spinoff of Unix, of course, that was the go-to handling complement for large educational mechanism systems, costly engineering workstations, and other he-man machines. Sun Microsystems formed a whole product line on (its possess chronicle of) Unix. The University of California during Berkeley had (its possess chronicle of) Unix. Telecom hulk ATT invented (its possess chronicle of) Unix. The whole C programing denunciation owes a existence to Unix. Its primary developers, Brian W. Kernighan and Dennis Ritchie, are so many a partial of mechanism science that their names are usually shortened as KR.

For a prolonged time, Unix was synonymous with large iron, and Linux was usually one of many choice attempts to tame a big, formidable beast and train it. It’s been a outrageous success, no question. Linux is flattering many a de facto choice for embedded designers who wish a entirely featured handling complement though tough real-time features. As such, it’s edged out many of a other non-RTOS choices. You’d have a tough time justifying because you’re not regulating (some chronicle of) Linux in place of an RTOS.

The program triage was flattering simple. If we had a unequivocally tiny system, we automatic on unclothed metal. Medium-sized systems got some arrange of RTOS or heart or runner or charge manager. Big systems got Linux. Easy.

But now we’ve got Linux on $5 single-chip MCUs. What happened to a large iron? Atmel says that about 25% of a business still do “bare metal” programming or use a tiny RTOS. The other 75% are regulating (some chronicle of) Linux. It can’t be prolonged before a whole handling complement comes preloaded in ROM. we give it twin years.

Back to a chips themselves, a new D2 family looks a lot like Atmel’s many other ARM-based chips, that is to contend it does a lot in a small package. There are 7 graphic chips in a D2 series, with a differences especially in wrapping and, necessarily, marginal mix. All share a same 500-MHz CPU, and all have a DDR3 memory controller. From there, a underline set gets a small tricky, depending on that of a 7 inclination we take a imagination to.

Some have CAN bus, for we automotive or industrial designers. Some can endure extended heat ranges. Some have HSIC, a chip-to-chip chronicle of USB that’s arrange of a complicated chronicle of I2C. (They have I2C, too.) And a few have recurrent confidence facilities to forestall tampering, reverse-engineering, and ubiquitous mischief.

All 7 new chips exaggerate a new audio subsystem that’s a good ascent from a brain-dead orator outputs that many MCUs have. It’s not an on-chip MP3 actor by any means, though it replaces a elementary PWM or bit-banging an outlay amplifier. In fact, a D2 chips have their possess Class D audio amplifier on-chip, so all we need is a handful of inexpensive analog components and you’re good to go; no DAC or outlay filter needed.

Although a chips all come with a DRAM controller, we can also configure them to work in a RAM-less mode, wherein a on-chip L2 cache is converted to SRAM. You’d have usually 256KB of RAM to work with, though it’s improved than zero if you’re disturbed about house space or complement cost. There’s also a twin QSPI interface that will bond we to off-chip peep memory, so your channel to outmost memory needn’t be utterly quick or wide. The SAMA5D2 processors are utterly happy to govern directly out of flash, too, so there’s no need to download or duplicate formula into a internal SRAM.

Want to do a user interface? The 24-bit TFT LCD controller is usually a ticket. It ain’t fast, though with 24-bit tone depth, displays will demeanour good and pretty. Combined with a new audio unit, your industrial user interface doesn’t have to rest on embarrassingly blocky icons and robotic beeps anymore.

Naturally, there’s an inexpensive analysis house and lots of giveaway motorist and growth software. And did we discuss a thing runs Linux? Best of all, a Atmel people never once mentioned “internet of things” during a discussion. Bonus points for originality.
