Network Bandwidth Too Low 0Kbps Error When Using PSI Secure Bridge For Online Testing

Image
Many people graduated from school thinking they do not need to worry about exams anymore. Guess what? Even adults face many different exams, for example, certain professions like accountants require licenses to practice and that means you have to study and pass their professional exams. For other industries like tech, you can acquire the latest skills without going for exams, but if you wish to show proof of your expertise, many technology companies offer their own set of progressive certifications or "tracks", which you can attempt and become better at. Microsoft, Amazon, and Google certifications have been leading due to the popularity of their cloud-related certifications. Traditionally, these technology companies work with exam providers such as Pearson Vue and PSI to have their exams conducted at the testing centres of these exam providers. The rationale being that these testing venues and equipment have been pre-vetted for exam security. Participants can schedule thei

You Can PPT Too! (Part Two): Useful Shortcuts With SHIFT

Image
Well, the second part took longer than I thought it would. Hopefully with some downtime now, I can get the other parts out sooner. So onto the main topic, in this article, I will talk about some useful and convenient ppt shortcut features, powered by a simple but useful key - the SHIFT key. Some of these may already be familiar to seasoned Powerpoint masters, but may not be immediately apparent to new users. If you know of any other tricks, I would love to hear from you in the comments :) Let's start by running through the more well-known uses for SHIFT: Selecting Multiple Objects This should be quite straightforward. Hold down the SHIFT key and select your objects, either one by one, or click and drag across the slide canvas to cover the objects you want. To finetune your selection, you can continue holding down SHIFT and click on individual objects that you want to add into or remove from your selection. Drawing Straight Lines Hold down the SHIFT key and draw you

You Can PPT Too! (Part One): How to use Alignment in Powerpoint for Professional Looking Slides

Image
PowerPoint has many interesting and time-saving features. I like to call them Quality of Life (QoL) features. For the most part, these QoL features make working with Powerpoint easier.  Unfortunately, some of these can be confusing for newcomers. At least, that was how I felt when I starting learning how to do better PPT presentations beyond the default templates. Why not do a mini-series to share some useful PPT tricks I have learned, I thought. And so I bring to you the first part of my "You Can PPT Too!" series.  Let's start with something simple. Simple and yet, I would often see neglected in presentations.  How many times have you sat through a presentation, only to have your attention drift away from the presenter because of untidy alignment, like the one on the left below? A little exaggeration on the alignment but it conveys my point. Not only do such minor details distract your audience, but they also convey sloppiness and are generally bad for professi

How to Control Xiaomi Web Camera Sharing Permissions

Image
This post came about as a result of another earlier post on  How to share a Xiaomi webcam/video camera to multiple Mi accounts . A reader wanted more privacy control over his web camera after being shared with other accounts but could not find the necessary settings. After a few backs and forth, it got apparent that even across Xiaomi products, the level of controls is not consistent and I thought this was worth a post by itself to show where to find the settings and get more feedback on the inconsistencies. Xiaomi is a big Chinese company selling various Smart Home devices and digital technology products. It is a very big brand in its home market and has been rising internationally due to its aggressive marketing and pricing strategies.  In terms of webcam products, Xiaomi has a few different series to cater to different market needs, so to set the context, I am using Xiaomi Home Security Camera 1080p (it's the China website because not all products are available in every

In Cloud Computing, What is the Difference Between Scalability and Elasticity

Image
In Cloud Computing, we often hear the terms 'Scalability' and 'Elasticity' being thrown around, often being used interchangeably. Recently, I was listening to an online course describing Cloud Computing concepts, and the way these two terms are described got me thinking about the differences. So far, there is no consensus on how to draw the line. I have seen explanations that put Scalability as adding resources while Elasticity as adding AND removing resources. I have also seen descriptions that say Scalability is to be able to scale an instance's resources, while Elasticity is to be able to add/remove additional instances. I am of the opinion that demarcating the differences purely from the perspective of resource adding and removing is too simplified and a little ambiguous, while the latter view of instance resource vs new instances is still talking about Scalability (Vertical Scaling vs Horizontal Scaling - explained at the end of this article).

Powerpoint File Size Does Not Reduce Even After Deleting Slides

Image
Updated 10 Jul 2018 - After some testing, I find that those "extra" template slides appear when you try to copy some slides and paste them to another deck with "Keep Source Formatting". So if you frequently encounter this problem, you could be like me, often having to take content from different decks and piece together a customized deck for the work on hand. If so, then the solution below should help with your Powerpoint file size. If you work with Powerpoint slides a lot, you may have seen some pretty big and bloated slide decks, especially if it contains lots of photos or video content. This presents an issue when sending over email with attachment size limits. Most of the time, deleting slides or compressing content should help to reduce the size.  If you had come upon this article after googling, you probably had just encountered a similar frustrating experience as me. Even after  removing most of the content, the Powerpoint file size remains mostly th
