How do I tackle machine learning in software testing?

Image result for How do I tackle machine learning in software testing?Welcome to the world of machine learning in software testing. Machine-learning software takes past data and uses that data to better understand and make decisions in a problem domain. It consists of a series of mathematical algorithms that are able to adjust themselves based on its understanding of that data. It won’t produce an exact answer, but it will usually produce one that is close enough to correct for its problem domain.

This type of software usually uses a technology called neural networks, which, to put it in a simple way, mimics the operation of the human brain. There are other technologies, such as genetic algorithms and rules-based systems, but most deep-learning systems are using neural networks.

Machine learning in software testing requires an entirely different approach. You will rarely, if ever, get the same result twice with the same input. Testing these systems requires a deep understanding of the problem domain and the ability to quantify the results you need in that domain. Are your results “good enough?” You have to internalize that a bug is more than just an unexpected output.

For machine learning in software testing, you should also have a high-level understanding of the learning architecture. You don’t have to read the code, but you do have to be aware of the architecture of your network and how the algorithms interact with one another. You might have to tell the developers that they have to toss out their approach and start over again. Don’t let the highly mathematical nature scare you. Machine learning in software testing is accessible to all testers with an open mind.

Do You Know What it Feels Like to Get Hacked?

Do You Know What It Feels Like To Get Hacked? | Social Media Today

Hopefully your answers is “no”, and the intention of this blog is to keep you cyber safe in 2017.

Remember the hack of the Ashley Madison site? The top 3 passwords used on that site were “123456”, “12345” and “password”.

While there are no guarantees that malicious actors won’t get to your information, the following tips will decrease the probability of having your personal information hacked.

Let’s do some cyber maintenance. In addition to changing your passwords, learn other ways to make your cyber presence safer.

1. Have Complicated, Unique, Difficult-To-Crack Passwords

Hate changing your passwords for your social media, online banking, Amazon.com and other online accounts? So do I. But having someone invade your privacy, social channels, or even financial information is a lot worse.

A good solution to create strong passwords (and track them at the same time) is to sign up for a password storage tool. 1Password carries a yearly fee, and I’ve also heard good things about a free tool called LastPass.

All you need to do, once you have such a tool, is to create one really complex password and remember it. Then you can let the tool auto-generate all your other long and tricky passwords, which you won’t need to remember.

2. Never Reuse a Password

Don’t use the same password or slightly modify it to use it on multiple accounts.

Make each password unique, with a mix of upper and lower case letters, numbers, special characters – at least 9 characters, ideally more.

3. Update Your Passwords Regularly

Change your passwords periodically (at least every 6-12 months). While having a really difficult password is the number one way to protect your accounts, changing your password can’t hurt.

4. Prevent “Dictionary Attacks”

Don’t use dictionary words, your pet’s name, your college or any other words that have an obvious correlation to you as a person. These are easy to find, even just via Google, and so-called “dictionary attacks” – which are extremely common and simple – can crack those passwords in no time.

NOTE: Personally, I also discourage publishing your birthday on LinkedIn or Facebook as this date is a crucial detail to cracking and taking over your (online) identity; especially in the USA where birth date and social security number ARE your identity.

5. Keep Your Security and Privacy Settings Current

Facebook, LinkedIn and other social media channels occasionally change their privacy options, which is easy to miss (or dismiss) as such updates are not particularly interesting.

For a safe 2017, visit your social channels and review your privacy and notification settings. While you’re there, disconnect access for apps you no longer use.

6. Enable Two-Factor-Authentication

Something often dismissed as too complicated is two-step-verification.

Most social platforms, banks and other accounts now provide this as an option – here’s how it works:

  • In addition to your password, every time you sign in, you get a text message or app notification with a code that you need to enter before you get access to your account.
  • You’ll be asked to specify your trusted device(s) to receive the code, e.g. your iPhone or iPad, so only you have access.

7. Don’t Store Passwords in Your Browser

I know, it seems convenient but hackers feel the same way.

Browser attacks are very common – here’s some more information on common threats by Kaspersky.

8. Have a Security Program Installed

You need a virus protection program at a minimum, and many of these now come with privacy packages to help you in case you do get hacked.

Here’s a suggestion for 10 virus protection programs. Also consider a service that alerts you to invasions into your personal information, like changes in your credit report. One option is Lifelock.

9. Install Software Updates

Don’t dally when it comes to installing updates to your applications, operating system or website. While I admit that I sometimes wait a few days when a new OS update comes out so that the main bugs can be fixed first, I never wait for more than a week.

10. Be Suspicious of URLs Before You Click

Phishing is generally an attempt to get users to click on a malicious URL that will upload a virus if you do.

Never click on a URL sent by your bank, PayPal or other account that requires you to sign in.

Often, malicious actors will steal your password that way, or upload a virus. Instead, go to the site directly and log-in from there to check on any message.

Also, be suspicious about the senders of any message you receive via email or social media. Sometimes when I see a shortened link, I ask the sender to give me the URL to look it up myself or I pass.

Android apps on Chromebooks: do not assume immediately magic

Android Apps Chromebooks - Chrome OS

well, gang, it is clearly taking place: the entire Google Play save of Android apps is beginning to show up on Chromebooks.

We first heard approximately the pass for the duration of Google’s I/O buildersconference closing month. And even as the capability to install Android apps won’t be gift for most Chromebook users until later this 12 months, Google is now within the midst of making the characteristic to be had at the advanced improvement channel of its Chrome OS operating machine (handiest on the Asus Chromebook flip for the time being but with different decided on devices set to comply with somedaysoon“).

To make certain, that is an early and neverthelesshardaround-the-edges version of the attempttherefore its appearance best at the Chrome OS improvement channel, that is designed for builders and early adopters to try out new features as they may be being organized. but nevertheless, I cannot help however suppose masses of tech-loving parents are going to technique this new functionality with expectancies of immediate magic.

allow me cross in advance and spoil it for you presently: There isn’t always going to be any form of wonderful “ahah!” second of surprise whilst you first encounter the Play shop on a Chrome OS tool. much more likely, there may be going to be a feeling of: “Oh. it’s it?” due to the fact giant because the feature is — and as we’ve got mentioned before, it without a doubt is a big deal — you need to examine it from a broader angle if you want to comprehend its genuine significance.

Bringing Android apps onto Chromebooks is first and primary about lessening a Chromebook’s obstacles. the largest immediately advantage is that it’ll allow Chrome OS customers perform duties which might be presently impossible at the platform — such things as accessing Microsoft’s full suite of office utilities, the usage of completely featured image editors, and making and receiving video calls on Skype (something the organisation‘s internet app bafflingly would not permit).

this stuff absolutely aren’t magical in and of themselves — due to the fact guess what? walking any given Android app on a Chromebook is quite plenty similar to going for walks it on an Android device. It isn’t always a few wild new enjoy it truly is gonna blow your thoughts the second one you strive it.

What it’s far going to do, though, is make Chrome OS greater versatile as a platform and for this reason greater feasible as a primary computing environment for extra peoplepeople like me who basically use net apps however still have a handful of wishes (just like the occasional opening of a report with Microsoft’s track modifications formatting in vicinity or the advanced modifying of a multilayered photograph) that internetbased totally utilities cannot effectively cope with.

what is important to keep in mind is that this pass is in the end about mixing structures together — taking two familiar entities and allowing them to overlap in a manner that benefits each. it is about increasing the usefulness of Chrome OS by way of bringing a chunk of Android into its size — and in doing so, broadening the platform’s enchantment and giving it a brand new level of lifestyles. That won’t deliver the type of on the spot thrill new-function-seekers wish to discover, however on the end of the day, it’ll % a far extra significant and a waysattaining advantage.

Google certainly has its paintings cut out for it in relation to making Android apps run smoothly on Chromebooks — from getting builders to update their apps for full compatibility to figuring out a way to cast off the confusion of having two overlapping app markets on a unmarried device. What we are seeing now could be simplest the start.

If the organisation manages to make this revel in a terrific one, though, this seemingly mundane first step ought to mark the start of something transformative. You just must step returned and examine the large image to comprehend the scope of its importance.
