    New York – Hacking a car is not a new field, but the secret of ‘success’ steal grounded sophisticated control of the car during the closed meeting. recently, two peratas successfully decode software commonly used among others by car thieves to disable siatem safety and escape easily incarannya car.

    Charlie Miller and Chris Valasek, the two hackers, said they would publish details of engineering blueprint to attack the security system in the Toyota Prius and Ford Escape. This 100-page findings compiled after several months of research they conducted with a grant from the U.S. government Sserikat.

    Two “white hats” – the nickname for hackers who try to uncover software vulnerabilities before criminals can exploit them – also will release software that they built for hacking a car in a hacker convention in Las Vegas this week.

    They say they found a way to force Toyota Prius brake suddenly at a speed of 80 miles per hour, determine the direction of the steering wheel, to speed up the machine. They also say that they can disable the brakes of the Ford Escape at very slow speeds, so the car continued to move no matter how hard the driver depresses the pedal.

    Both men said they hope the data they publish will encourage other white hat hackers to uncover security flaws more advanced automotive products that can be fixed.

    “I believe the 100 eyes of security researchers more powerful than the eyes that are in Ford and Toyota,” said Miller, a well-known security expert who was formerly known Twitter reveals burglary of Apple Inc. App Store.

    Toyota Motor Corp. spokesman John Hanson said the company is reviewing its security systems car after referring to their findings. He said the automaker to invest in electronic security, although they acknowledge hackers continue to find loopholes.

    “It is impossible to do,” said Hanson, referring to the newly exposed hacking. “Certainly we take it seriously.”

    Being a spokesman for Ford Motor Co., Craig Daitch, said the company considers the vehicle electronic security seriously. But he guarantees that the product is now in the hands of consumers is equipped with adequate safeguards.

    TAIWAN – For fans of PC assembling, hardware component selection would be kept. One important component to keep the processor temperature is kept cool by using a CPU fan.

    Cooler Master, a Taiwanese hardware manufacturer announced a new CPU fan with a futuristic design. Reported Hardware.info, Sunday (07/21/2013), the cooling fan by the name GTS V8 comes with more impressive design.

    This cooling technology based on the Horizontal Vapor Chamber (HVC), who appeared with eight heatpipes measuring 6 mm. The device is capable of transferring up to 250 watts of heat to three separate aluminum heatsink.

    Heatsink will keep cool thanks to the two measuring 140 mm PWM fan in a configuration called ‘push-pull’ (push-pull). Cooler Master claims to parts of the fan case will be able to last longer.

    By reducing friction, must endure V8 GTS 160 thousand hours at speeds between 600 and 1600 rpm. GTS V8 has a dimension of 154 x 149.8 x 166.5 mm and weighs 1140 grams.

    Cooler Master V8 GTS is scheduled to launch in September this year. Company offers its flagship CPU fan with a price tag of 80 euros or approximately Rp1 million.

  • 5 Coding Hacks to Reduce GC Overhead

    Comments Off on 5 Coding Hacks to Reduce GC Overhead
    December 8, 2019 /  Computer Technology, Programming

    In this post we’ll look at five ways in roomates efficient coding we can use to help our garbage collector CPU spend less time allocating and freeing memory, and reduce GC overhead. Often Long GCs can lead to our code being stopped while memory is reclaimed (AKA “stop the world”). Duke_GCPost

    Some background

    The GC is built to handle large amounts of allocations of short-lived objects (think of something like rendering a web page, where most of the objects allocated Become obsolete once the page is served).

    The GC does this using what’s called a “young generation” – a heap segment where new objects are allocated. Each object has an “age” (placed in the object’s header bits) defines how many roomates collections it has “survived” without being reclaimed. Once a certain age is reached, the object is copied into another section in the heap called a “survivor” or “old” generation.

    The process, while efficient, still comes at a cost. Being Able to reduce the number of temporary allocations can really help us increase of throughput, especially in high-scale applications.

    Below are five ways everyday we can write code that is more memory efficient, without having to spend a lot of time on it, or reducing code readability.

    1. Avoid implicit Strings

    Strings are an integral part of almost every structure of data we manage. Being much heavier than other primitive values, they have a much stronger impact on memory usage.

    One of the most important things to note is that Strings are immutable. They can not be modified after allocation. Operators such as “+” for concatenation actually allocate a new String containing the contents of the strings being joined. What’s worse, is there’s an implicit StringBuilder object that is allocated to actually do the work of combining them.

    For example –

    1
    a = a + b; / / a and b are Strings
    The compiler generates code comparable behind the scenes:

    1
    StringBuilder temp = new StringBuilder (a).
    2
    temp.append (b);
    3
    a = temp.toString () / / a new string is allocated here.
    4
    / / The previous “a” is now garbage.
    But it gets worse.

    Let’s look at this example –

    1
    String result = foo () + arg;
    2
    result + = boo ();
    3
    System.out.println (“result =” + result);
    In this example we have 3 StringBuilders allocated in the background – one for each plus operation, and two additional Strings – one to hold the result of the second assignment and another to hold the string passed into the print method. That’s 5 additional objects in what would otherwise Appear to be a pretty trivial statement.

    Think about what happens in real-world scenarios such as generating code a web page, working with XML or reading text from a file. Within a nested loop structures, you could be looking at Hundreds or Thousands of objects that are implicitly allocated. While the VM has Mechanisms to deal with this, it comes at a cost – one paid by your users.

    The solution: One way of reducing this is being proactive with StringBuilder allocations. The example below Achieves the same result as the code above while allocating only one StringBuilder and one string to hold the final result, instead of the original five objects.

    1
    StringBuilder value = new StringBuilder (“result =”);
    2
    value.append (foo ()). append (arg). append (boo ());
    3
    System.out.println (value);

  • Facebook shares rallied an impressive 30% Thursday, allowing the stock to book its best one-day gain ever. And while shares remain about 10% below the May 2012 IPO price of $38, analysts are predicting that Facebook is finally on its way to reaching, and even crossing, that threshold.

    “Facebook delivered its strongest quarter yet as a public company — results that we think could be thesis-changing for many,” said Doug Anmuth, a JPMorgan analyst who boosted his price target to $44 a share from $35.

    Investors and analysts are most impressed by Facebook’s growing strength in mobile advertising — a part of the business they were initially most concerned about since Facebook lacked a clear strategy for mobile advertising despite the rapidly growing number of people using Facebook on their mobile phones and tablets.

    “One year into Facebook’s mobile advertising efforts, mobile has increased from zero to 41% of total ad revenue,” Anmuth highlighted in a note to clients.

    While the improvements have been gradual, Facebook blew everyone away this past quarter by generating 50% more in mobile ad revenue than what Wall Street was expecting.

    Even after that stellar quarter, analysts say growth should remain strong as Facebook continues to shift toward more social ads that will become increasingly valuable to advertisers.

    Analysts at JMP Securities, who increased their share price target to $38, said that social media giant’s second-quarter results suggest that “Facebook is increasingly becoming a ‘must buy’ for advertisers.”

    Goldman Sachs analysts were also excited by Facebook’s significant improvement in mobile advertising. They put a bullish price target of $46 on Facebook shares.

    “We continue to believe Facebook is at the center of the mobile ad revolution and see considerable opportunity for it to drive higher pricing on its ad units as brand and direct marketers alike take advantage of its broad reach and precise targeting,” said Goldman analyst Heather Bellini.

    As Facebook (FB) shares surged, a number of investors were getting in on the action. Over 360 million shares of Facebook had exchanged hands Thursday, more than seven times the stock’s average daily trading volume.

    The day’s surge pushed the value of Facebook to more than $80 billion, up from just over $60 billion as of Wednesday’s closing bell.

    Facebook’s advance was also getting plenty of attention on Twitter.
