We have to admit, we have an odd fascination with WSL — the Windows subsystem for Linux. On the one hand, it gives us more options on Windows 10 for running the software we love. On the other hand, we wonder why we aren’t just running Linux. Sometimes it is because our cool laptop doesn’t work well on Linux. Other times we are using someone else’s computer that we aren’t allowed to reload or dual boot. Still, as long as we have to use Windows, we are glad to have WSL. A recent blog post by [Hanselman] shows some very cool tricks for using WSL that make it even better.

Exploring WSL

Did you know you can use WSL to run Linux commands in a Windows command shell? For example, you have a long directory and you want to run grep:

dir c:\archive\* | wsl grep -i hackaday

Of course, from bash you could access the same directory:

ls /mnt/c/archive | grep -i hackaday


Many of the tricks rely on the fact that bash doesn’t assume any executable file extension. If you try to run explorer, for example, from a bash shell, nothing happens. But if you append the .exe extensions, Windows programs will run and, by default, the usual Windows directories are in the path.

You do need to watch out for path name conversion. For example, if you provide “.” as an argument to explorer, you will open up a network share //wsl$/Ubuntu/home/user_name, for example. Of course, that’s another trick. You can access your WSL directories from windows using that notation (obviously, Ubuntu and user_name may be different for your installation). However, ordinary paths do not work.

Path Conversion

You can, however, use the wslpath utility to convert paths in both directions:

$ wslpath
-a force result to absolute path format
-u translate from a Windows path to a WSL path (default)
-w translate from a WSL path to a Windows path
-m translate from a WSL path to a Windows path, with '/' instead of '\'

For example:

$ explorer.exe `wslpath -w /bin`

X11 and More

[Hanselman] discusses a number of tips, including some about using development tools and git. You can also install multiple WSL flavors and export them to other Windows machines. He also mentions running X11 using paid tools Pengwin and X410. We say just use Swan.

Speaking of Swan, it is a great alternative to WSL on any Windows version, not just Windows 10. In truth, it is just Cygwin with X11 preconfigured, but it is much easier than trying to get X11 running on a bare Cygwin install. On the one hand, this is a much more desktop Linux solution than WSL. On the other hand, WSL loads real distributions and integrates nicely with Windows 10. But if you load both, you can get the advantages of both, too.

Sell Out?

Given the choice, we’ll just use Linux. Honestly, if your workflow is mostly Web-based, it hardly matters anymore. You load Chrome or your choice of browser and everything works. Of course, our Linux boxes tend to be way more efficient and also stay running better than Windows.

However, if you find yourself using Windows, Cygwin has long been a big help. Now WSL is another tool to get your Linux tools on a Microsoft-controlled box.

Killexams : GitHub flaw tricks developers into downloading malicious code

Security researchers at Checkmarx have uncovered a software supply chain attack technique that tricks developers into downloading malicious code on GitHub.

Threat actors can carry out their nefarious activities by spoofing and forging data on GitHub. Using this technique, attackers are able to falsify the timestamp and identity of the user responsible for a particular change to a repository.

The researchers said the attackers capitalize on the trustworthiness and reputation commonly associated with frequent GitHub contributors and their repositories.

GitHub provides commit data from developers with years of experience in activity, and the commit data in the activity graph is made available on the user’s profile page, making it easier for developers to select their preferred open source projects.

However, this data provided by GitHub can be manipulated by threat actors by fabricating many commits. Checkmarx explained that it is virtually impossible to verify the authenticity of commits because such activities on GitHub are displayed in public and private repositories.

Forging a reputable contributor’s data is simple and essentially involves the attacker knowing the user’s email address, then setting the username and email address on the Git command line and making changes on the user’s behalf.

Killexams : The New SAP Store for Mobile Apps: Yep, It's Kind of a Big Deal.

They say you can't teach old dogs new tricks. So what about Big Dogs?

For the first 35-odd years of its existence, SAP only marketed and sold its own software. We weren't a platform vendor like Microsoft (Windows), Google (Android) or Apple (Mac OS X, iOS). So we didn't need to woo, support or sell other developers' applications.

It was a self-centered strategy that was borne out of a need to serve the many customers clamoring for our applications, as well as fend off our many rivals - IBM, Oracle, Microsoft and others.

You know how the story turned out: SAP grew to become the market leader (by revenue) in ERP, CRM, and business intelligence/analytics software. The Big Dog, in other words.

But as the enterprise market matured, it posed major challenges to SAP. Rather than rolling over and playing dead, we learned some new tricks.

One of those was launching the SAP Ecohub, an online marketplace for partner software and solutions, in 2008.

As independent analyst Dennis Howlett put it at the time: "EcoHub is a step in a fresh direction for SAP which has been perceived as a company that doesn’t sell products that are ‘not made here.’"

Three years later, SAP offers more than 1,000 partner-built applications via the EcoHub and other channels.

Even bigger than EcoHub was SAP's $5.8 billion purchase of Sybase. Though also falling in the general category of enterprise software, Sybase has always been more of middleware and platform company than applications vendor ala SAP. It's always cultivated developers and partners to build applications that connect to its ASE database or run on top of the Sybase Unwired Platform (SUP).

With these two moves, the next was a no-brainer: releasing our own Enterprise App Store. Called the SAP Store for Mobile Apps, it opened up stealthily on Halloween with more than 50 SAP and SUP-certified apps from partners today, ranging from sales to productivity to human capital management (HCM) running on iOS, BlackBerry and other platforms.

Debuting at the SAPPHIRE NOW + TechEd conference in Madrid this week, the Store is a key part of our strategy to build up an SAP-centric mobile ecosystem.

Even as SAP rushes to release more and more apps that connect with our applications, our goal is to have 80% of all mobile apps be built by partners.

So far, we're not doing too bad. For SAPPHIRE NOW, 20 partners submitted 200 apps to be shown on the show floor. 100 were chosen (check them out at the SAP Partner Mobile App Catalog).

Why are developers starting to come to the SAP Store for Mobile Apps and otherwise build for SAP? I asked Usman Sheikh, the vice-president at EcoHub in charge of the new enterprise app store. He answered my questions and, helpfully, shared these slides.

As I discussed in my blog, 'How Many Kinds of Enterprise App Stores are There Today?', vendors are starting to deploy their own enterprise app stores, in order to provide a blend of the features in consumer-oriented app stores (easy browsing, instant purchase and download) and the kind of features required by enterprise users: flexible payments (credit card or corporate invoice), company discounts, the ability to check if your device or OS version is compatible with the app, as well as certification (by SAP) that apps will work with back-end systems, confirmed Sheikh.

Other features include pre-sales support for potential customers. These include a 1-800 number and chat and e-mail to reach SAP reps as well as the original partner developer. This supports the higher-touch model preferred by customers forking over not $1.99 per app, but potentially hundreds of dollars or more.

To accommodate line-of-business users who prefer to quickly get the app running in order to kick the tires themselves, SAP is offering its app store as an iOS app. See the screenshot below.

Longer-term, the SAP Store for Mobile Apps will be tightly integrated with the Sybase Afaria mobile device management software. Within weeks, users should be able to launch the SAP Store from within Afaria, said Sheikh. Afaria will also eventually be able to communicate with the Store so that only apps consistent with an employee's role in a company are displayed, as well as help configure and install new apps. That integration will continue to grow. "Afaria will be the preferred MDM solution," he said.

The Store not only supports apps built on Sybase's SUP app development platform, but also apps built using other technologies such as the cloud-based Business ByDesign or SAP NetWeaver Gateway, Sheikh said. See the chart below.

And what about the all-important financial terms? Developers will get an 85% share of all app license and subscription revenue garnered through the Store, said Sheikh. In other words, SAP is taking 15% - just half of Apple's 30% take for its App Store. Developers are not bound by exclusivity agreements, said Sheikh.

Sheikh said SAP will "respect" developers who wish to offer their apps on a freemium basis - i.e. free versions that can be converted later into paid via in-app purchases - but expects to receive their 15% cut of those subsequent in-app purchases.

As mentioned, apps must be certified by SAP before they can be sold on the Mobile Apps Store. That is free for the rest of the year.

How about for 2012? "It will be reasonable and competitive," Sheikh said.

For now, the SAP Store for Mobile Apps will be focused on apps that either run on SUP middleware or explicitly hook into SAP server applications. But Sheikh anticipates the Store eventually growing to support more general productivity and business apps, provided they are relevant to SAP users.

Granted, the Store remains in beta today. Many of the features mentioned above, such as credit card purchasing and the ability to selectively offer apps to users based on their job role, won't be ready til first or second quarter next year.

Even still, can you name another vendor-operated enterprise app store that is more advanced than SAP's? If so, please share with me and other readers. For now, I think SAP Store is further proof that big dogs can learn new tricks.

Killexams : Which of the following was not a x86 CPU maker?

Choose your answer and the correct choice will be revealed.

IBM was involved in the development of x86 systems since their inception, at some point designing and manufacturing x86 processors intended for PCs as well as embedded systems.

Cyrix was a microprocessor developer founded in 1988. They specialized in math coprocessors for 286 and 386 microprocessors. IBM partnered with Cyrix to produce what would become their most notorious products, released around the Intel Pentium era, the Cyrix 5x86 and 6x86 CPUs. Cyrix was acquired by National Semiconductor in 1997, later folding into one of Texas Instruments divisions.

VIA was another active x86 CPU maker in the 1990s specializing in low-power solutions after acquiring IDT Centaur, marking its entry into the microprocessor market with the VIA C3, VIA C7 and VIA Nano processors. VIA continues to produce chips through Zhaoxin, a joint venture with the Shanghai Municipal Government that operates in the Chinese market.

Motorola was one of the first semiconductor companies in the world, with a rich history of microprocessors used in various applications, but never having developed a x86 class processor for the PC market. Motorola's semiconductor division was spun off into two makers of its own: ON Semiconductor which operates to this day, and Freescale Semiconductor. The latter was acquired by NXP in 2015, which years later was bought out by Qualcomm.

Killexams : Blockchain: A few missing pieces is all Web3 needs

By Mehab Qureshi

The internet has been around for only a few decades, but it has become impossible to imagine living in a world without it. Now, many are betting on an improved, decentralised version of the internet we see today, commonly known as Web3. In fact, Web3 is billed as the ‘next big thing’. It is expected to be more democratised and decentralised, being harnessed by the power of blockchain technology.

“But for that a number of things need to happen, such as interoperability between chains, and higher security. One component that Web 3.0 cannot materialise without is real-time data,” says Chet Kapoor, chairman and CEO of DataStax. Kapoor has more than 20 years of leadership experience at innovative software and cloud companies, including Google, IBM, BEA Systems, WebMethods, and NeXT.

For Web3 to take off, it also needs a “killer app”, one that drives everything. “What really made Android take off? It wasn’t only a good operating system, but turn-by-turn directions on Google Maps. It was unique, available only on Android.

I don’t think people have come up with something unique on Web3 yet,” he says.

Kapoor believes India could be the country to make this happen, since it has a tonne of talent, along with a massive population. “Every product company struggles with a couple of primary problems: Do you have enough engineers, and do you have enough users? Companies in India don’t face either of these problems. ”

The blockchain space remains scattered at present. While it is believed to have the potential to power the ‘internet of the future’, it lacks certain features that are needed to connect it more thoroughly and help it fulfill Web 3.0’s promise. Most important, it lacks the main component – real-time data – that will allow it to go big, similar to how Web 2.0 (the modern-day internet) exploded. This is a well-recognised issue and some are working towards resolving it.

DataStax is making the Ethereum blockchain available as a service to users. Developers can use an open API, file any queries – and have access to real-time data.

It has uploaded the entire Ethereum blockchain into a database. Some entities are even building global payment settlement networks that are based on blockchain while maintaining systems of engagement outside of the blockchain. But the question of how blockchain can help when you need real-time data needs to be answered.

Banks are already starting to do reconciliations with blockchain. Kapoor says, “Whenever a transaction happens in a bank, and there’s another in a different bank, a lot of processing is needed to reconcile them. And that can happen on blockchain because it’s transparent. Blockchain is starting to make its way to the back offices of banks.”

One of the biggest factors driving Web3 is the metaverse. Both technologies support each other perfectly. Kapoor compares the growth in iPhone sales with the metaverse. Angry Birds and Zynga were the first gaming apps on the iPhone. “These showed people how to interact with the device, but they were not game-changing applications,” he says, adding that “this is the stage Metaverse is at today. The version 2.0 apps on Metaverse will get really interesting.”

Killexams : IBM Q2 revenue report surpasses analyst estimates

Strong demand at IBM’s consulting and infrastructure business helped the hardware giant post second-quarter revenue of C$15.54 billion, exceeding analyst estimates of C$15.18 billion.

IBM posted an adjusted gross profit margin of 54.5 per cent for the quarter ended June 30, compared with an average of 56.6 per cent expected by analysts.

IBM’s cloud revenue rose 18 per cent to C$5.9 billion. Excluding special items, the company earned C$2.31 per share, exceeding estimates of C$2.27.

IBM is banking on high-growth software and consulting businesses with a focus on the so-called “hybrid cloud.” Despite the ongoing turbulence, the company expects continued revenue growth in regions such as Europe and Asia-Pacific.

Chief Financial Officer James Kavanaugh explained that a strong U.S. dollar and heightened political tensions had put pressure on the company’s near-term results.

Kavanaugh said, however, that the company is sticking to its full-year guidance of reaching the upper end of mid-single-digit revenue growth at constant currency.

Contrary to an earlier forecast of 3 per cent-4 per cent, IBM now expects a foreign exchange impact on sales of about 6 per cent this year.

Killexams : The real cost of Facebook’s controversies: Nearly $150 billion in market cap gone in 90 minutes

The Facebook stock tanked back in March when the Cambridge Analytica user privacy scandal hit, and it took the company quite a while to recover. In the process, Facebook vowed to Excellerate protections for user data, rolled out GDPR-friendly user data management tools, and promised to investigate other developers who may have abused access to Facebook data. Mark Zuckerberg faced hearings in the US and Europe, and while he did not address all the issues raised in regards to Facebook’s business practices, the stock recovered.

But it all came crashing down on Wednesday, after Facebook posted earnings for the second quarter of the year, and during the conference call that delivered the horrible news about Facebook’s short-term prospects.

Facebook lost nearly $150 billion in market value in 90 minutes, Business Insider reports. That’s huge. To put things in perspective, IBM’s market cap is at $134 billion.

Facebook’s Q2 results missed Wall Street expectations for revenue and the number of daily and monthly active users. That caused a dip of 8% on the news, and the stock stayed there up until Facebook’s chief financial officer David Wehner started discussing the fiscal outlook.

The exec said Facebook’s revenue growth would slow from the 42% posted in the June quarter, and operating margins will fall from 44% during the period.

During the call, the stock fell more than 24%, wiping $148 billion in market cap at its lowest point. The stock closed at $217.50 on Wednesday, dropping as low as 165.96 in after hour trading. The stock recovered somewhat since then, but it’s trading at $180 at the time of this writing, which is still down more than 17%.

Back in March, the stock fell from around $185 to $152 on the Cambridge Analytica news, and it needed almost two months to recover.

This time around, it may take Facebook longer to bounce back, as Wehner’s forecast didn’t look good.

“Looking beyond 2018, we anticipate that total expense growth will exceed revenue growth in 2019,” he said. “Over the next several years, we would anticipate that our operating margins will trend towards the mid-thirties on a percentage basis.”

He warned analysts not to expect the company’s financials to get better anytime soon saying that the sub-par operating margins will last for “several years… more than two, less than many.”

Facebook’s privacy scandals have hurt the company’s bottom line and will continue to do so for quite a while. Facebook is now forced to let users better manage their data including opting out of some data collections.

According to Wehner, two other factors hurt Facebook’s bottom line, including the dollar’s decline this year, and Facebook’s pivot to Stories, which don’t bring in as much money as other features.

If there was one good news during the earnings call, it came from Zuckerberg who said that some 2.5 billion people use at least one of Facebook’s apps each month. That wasn’t enough to prevent the bloodshed.
