Together with AMD, Toshiba Offer Notebook PC

JAKARTA – Toshiba notebook to hit the market back in the homeland. Having recently launched a dual function, this ultrabook, Toshiba re-introduced its notebook personal computer (PC) in Indonesia under the name Toshiba Satellite C40D.

Toshiba Satellite C40D which is the development of TV technology from Toshiba, claimed more powerful and rich graphics. The kitchen was redone powered by Quad-Core AMD A4 APU.

Channel Manager of Toshiba Singapore, Albert Susilo states, with the audio technologies V2 Toshiba Audio Enhancement Technology, the consumer ear audio quality spoiled by sharp and clear. “Crystal clear,” he said at the launch of the Toshiba Satellite C40D at Le Meridien Jakarta, Monday (8/7).

With a unique design and is claimed to be better than the previous generation, Toshiba Satellite C40D available with spans 14.0 HD screen. The price is pegged at under $ 5 million. “Toshiba Satellite C40D be available in the Indonesian market in early July at a price of USD 439,” said Albert Susilo.

While AMD Indonesia Country Manager, Jenny Susanto said all products from AMD’s APU is designed to provide the best computing experience. “This notebook is instantly able to deliver sharp image quality, color, and more life to improve the consumer experience in watching the video,” he said.

Jenny added, AMD has always made ​​a breakthrough to provide the latest experience that not only includes the traditional architecture, but also the latest graphics processing interface. To provide experience productivity, graphics, and entertainment, this notebook is reinforced with a variety of the latest exclusive technology from Toshiba and AMD.

Facebook Hashtags Not Catching on With Consumers

While using hashtags in Facebook posts might be a fun tactic for brands trying to engage consumers, it doesn’t appear to be paying off, a new study finds.
Research from social media analytics firm Simply Measured revealed that while 20 percent of Facebook posts among top brands now include hashtags (which give users a way to group messages of similar content), there is no evidence that hashtags are influencing engagement.

The study shows that posts with hashtags —a new feature added with in the last several months — perform as well as those without, suggesting that people are not yet discovering brand posts by their tags.

Overall, the study shows nearly all of the companies in the Interbrand 100 — which ranks businesses based on financial status — now have a Facebook fan page, with 60 percent posting something at least once a day.

[No, Really, Facebook Makes Employees More Productive]

The research revealed that visual content is by far the primary driver for engagement on Facebook. Photos posted by top brands average more than 9,400 engagements, which includes likes, comments and shares, per post, while video posts average more than 2,500.

When it comes to text posts, brands must walk a fine line. Analysis of more than 500 status updates from the top brands shows that the longer a status update is, the less engagement it typically receives. However, if a status update is too short — less than 50 characters — it may not be long enough to capture viewers’ attention or provide the necessary context to drive the number of likes, shares and comments a brand would like.

“For most brands, Facebook is no longer just a network; it has become the hub of their social marketing efforts and one of the most effective ways to engage with fans,” said Adam Schoenfeld, CEO of Simply Measured. “This latest research once again proves that knowing your audience, understanding your content assets and measuring your efforts are extremely important to develop the social strategies that will work best for you.”

Businesses that limit Facebook fans from writing on their page might want to reconsider their strategy. The research shows that nearly 30 percent of top brands do not allow users to post on their wall. For those brands, user engagement on their page is limited to likes, comments and shares, resulting in 15 percent less engagement than brands that do allow user posts.

When it comes to drawing the most Facebook fans, no one does it better than Facebook itself. The social media giant claims the top spot with 93 million fans, followed by Coca-Cola and MTV.

Seven signs of dysfunctional engineering teams

I’ve been listening to the audiobook of Heart of Darkness this week, read by Kenneth Branagh. It’s fantastic. It also reminds me of some jobs I’ve had in the past.

There’s a great passage in which Marlow requires rivets to repair a ship, but finds that none are available. This, in spite of the fact that the camp he left further upriver is drowning in them. That felt familiar. There’s also a famous passage involving a French warship that’s blindly firing its cannons into the jungles of Africa in hopes of hitting a native camp situated within. I’ve had that job as well. Hopefully I can help you avoid getting yourself into those situations.

There are several really good lists of common traits seen in well-functioning engineering organizations. Most recently, there’s Pamela Fox’s list of What to look for in a software engineering culture. More famous, but somewhat dated at this point, is Joel Spolsky’s Joel Test. I want to talk about signs of teams that you should avoid.

This list is partially inspired by Ralph Peters’ Spotting the Losers: Seven Signs of Non-Competitive States. Of course, such a list is useless if you can’t apply it at the crucial point, when you’re interviewing. I’ve tried to include questions to ask and clues to look for that reveal dysfunction that is deeply baked into an engineering culture.

Preference for process over tools. As engineering teams grow, there are many approaches to coordinating people’s work. Most of them are some combination of process and tools. Git is a tool that enables multiple people to work on the same code base efficiently (most of the time). A team may also design a process around Git — avoiding the use of remote branches, only pushing code that’s ready to deploy to the master branch, or requiring people to use local branches for all of their development. Healthy teams generally try to address their scaling problems with tools, not additional process. Processes are hard to turn into habits, hard to teach to new team members, and often evolve too slowly to keep pace with changing circumstances. Ask your interviewers what their release cycle is like. Ask them how many standing meetings they attend. Look at the company’s job listings, are they hiring a scrum master?

Excessive deference to the leader or worse, founder. Does the group rely on one person to make all of the decisions? Are people afraid to change code the founder wrote? Has the company seen a lot of turnover among the engineering leader’s direct reports? Ask your interviewers how often the company’s coding conventions change. Ask them how much code in the code base has never been rewritten. Ask them what the process is for proposing a change to the technology stack. I have a friend who worked at a growing company where nobody was allowed to introduce coding conventions or libraries that the founding VP of Engineering didn’t understand, even though he hardly wrote any code any more.

Unwillingness to confront technical debt. Do you want to walk into a situation where the team struggles to make progress because they’re coding around all of the hacks they haven’t had time to address? Worse, does the team see you as the person who’s going to clean up all of the messes they’ve been leaving behind? You need to find out whether the team cares about building a sustainable code base. Ask the team how they manage their backlog of bugs. Ask them to tell you about something they’d love to automate if they had time. Is it something that any sensible person would have automated years ago? That’s a bad sign.

Not invented this week syndrome. We talk a lot about “not invented here” syndrome and how it affects the competitiveness of companies. I also worry about companies that lurch from one new technology to the next. Teams should make deliberate decisions about their stack, with an eye on the long term. More importantly, any such decisions should be made in a collaborative fashion, with both developer productivity and operability in mind. Finding out about this is easy. Everybody loves to talk about the latest thing they’re working with.

Disinterest in sustaining a Just Culture. What’s Just Culture? This post by my colleague John Allspaw on blameless post mortems describes it pretty well. Maybe you want to work at a company where people get fired on the spot for screwing up, or yelled at when things go wrong, but I don’t. How do you find out whether a company is like that? Ask about recent outages and gauge whether the person you ask is willing to talk about them openly. Do the people you talk to seem ashamed of their mistakes?

Monoculture. Diversity counts. Gender diversity is really important, but it’s not the only kind of diversity that matters. There’s ethnic diversity, there’s age diversity, and there’s simply the matter of people acting differently, or dressing differently. How homogenous is the group you’ve met? Do they all remind you of you? That’s almost certainly a serious danger sign. You may think it sounds like fun to work with a group of people who you’d happily have as roommates, but monocultures do a great job of masking other types of dysfunction.

Lack of a service-oriented mindset. The biggest professional mistakes I ever made were the result of failing to see that my job was ultimately to serve other people. I was obsessed with building what I thought was great software, and failed to see that what I should have been doing was paying attention to what other people needed from me in order to succeed in their jobs. You can almost never fail when you look for opportunities to be of service and avail yourself of them. Be on the lookout for companies where people get ahead by looking out for themselves. Don’t take those jobs.

There are a lot of ways that a team’s culture can be screwed up, but those are my top seven.

Intel’s new CEO and Atom chip face uphill climb to mobility

Intel announced earnings Wednesday that were in line with expectations, but the chipmaker is facing a daunting future as mobile devices further erode the PC business and its Atom chip vies for customers.

“With its new, low-end Atom processor, Bay Trail, the company is gaining traction in cheap notebooks and tablets, but we believe this is at the expense of higher-end core processors,”said Piper Jaffray analyst Gus Richard. “Intel is late to the smartphone market and we believe high-end smartphone sales are starting to roll over. Intel is far behind its competitors in terms of cost and integration in smartphones, in our view. We do expect Windows 8.1 to drive a corporate upgrade cycle next year, creating a bounce in PC demand.”

Intel’s new CEO Brian Krzanich said organization, strategic, and prioritization changes “will drive greater emphasis on our Atom-based products, bringing the full weight of our process and architectural leadership to the Atom family.”

Asymco’s Horace Dediu illustrates the dynamics of Intel’s situation — he calls it a “PC calamity” — which is similar to the situation facing Microsoft, a dominant leader in the PC era facing a steep uphill climb in the mobile era.

In the last six years, nearly as many iOS and Android devices have been sold as PCs and mobile ARM devices are selling at least 2.6 times the rate of Intel-powered devices.

“In terms of installed base, a computing category that did not exist six years ago has come to overtake one that has been around for 38 years,” Dediu wrote. “The calamity for Intel has been that they have had no part to play in the new category. Perhaps that is because they had every part to play in the old category.”

As you would expect, during the Intel earnings call Krzanich was optimistic about the potential for Atom processors to get traction in the fast-growing mobile space.

“Look at it as a constant pushing of the accelerator down and the thing just gets faster and faster as time goes by. And so you’ll just see more and more strength of that Atom line as time goes through here, and it will be kind of just, you’ll look back and say well it’s obviously that the Atom line has truly become strong and they’ve got share in the tablet space,” he said.

Intel trimmed its annual financial outlook from low single-digit percentage growth to to flat year over year.

Acquainted with BASH Scripting

It is undeniable that over time, the popularity of Linux is increasing every day. Linux Kernel project which was originally just a fun project by Linux apparently transformed into a project that became the basis for the evolution of the digital world today.

We can see that more and more digital devices are therein using Linux in it. Changes were made in all areas so that Linux can be used by all users, both from the ground level up to the experts though.

One thing that remains a hallmark of Linux is the existence of a shell that is never lost on any Linux distro. Shell is a command-line interpreter on duty to translate the commands entered by the user directly to the system through the help of a terminal or console as a zoom interface (such as Command Prompt on the Windows platform). Although today most of the Linux distributions already to offering graphical display, the shell is still regarded as one of the strengths of Linux shell bridge where users can interact with the system in order to be more flexible. Many things can be done on a shell because we are dealing directly with the system, coupled with the many variants of the shell that offers a variety of features in it, such as csh, sh, bash, ksh, tcsh, ash, zsh, etc.

One of the most common type of shell used is BASH (Bourne-Again Shell) which was created by Bryan Fox in 1988. Shell is a replacement of the Bourne Shell (sh) existing first and is still used in some Linux distributions. Currently BASH shell has become a de facto standard for almost all Linux distributions because it is considered the most feature-rich and has a fairly high degree of portability. For comparison between variants shell can be seen on the Wikipedia website

To be able to understand the Linux system with better and also improve your productivity and take advantage of the flexibility offered by Linux, so it’s good we are trying to learn programming BASH script. PCplus using Slackware Linux distro, but this tutorial can be applied to all Linux distributions for use BASH version 4.2 and above. You can use any text editor because basically BASH script is plain text file. You can also try it on a Windows platform with the help of Cygwin,

open the editor:

1. The first step in creating a shell script is telling the system what shell you want to use, because it could be available in a Linux distribution over the shell variant. Because we want to use bash, then write this line in the first row of each bash shell script that will be created

This code is called the shebang and a special instruction that will determine what the interpreter is going to be used to process a shell script. For example, for a script that utilizes Perl interpreter, it will contain information

2. Because the shell script is basically able to execute commands on the shell, then we can run shell commands from a shell script. For example, we want to display today’s date along with the name that we use username to login. Use the code on the listing-1 as an example. Before you can run the script, give it execute permissions on the file with the command chmod + x’s listing (adjust the file name you gave) then run the command.

Date command displays the current date information while whoami will menapilkan your user information to login.

3. What if we want to display the text coupled with a shell command? Use the echo function to display a message to the screen shown in listing-2. Echo function accepts parameters in the form of a text message that will be displayed kelayar. You might ask, why the date and user information are on different lines with text displayed? This is due essentially echo function will display a message and then change the next line. To be able to display an information to the right of the text is displayed, use the-n parameter on the function like echo in the listing-3.

4. You can try some of the commands contained in the location / bin and / usr / bin. If not sure of the usefulness of a command, run the command man <nama-perintah> on the console or terminal, for example, man ls and manual information about the ls command will be displayed. Each command has a variation of different parameters with each other, so there are times when we have to read the manual to know every option available.
