Now that you've secured your account, you may want to clean up your post by deleting all the spammy tweets and direct messages. This can be done by either clicking on delete or on the symbol of the trash can or clicking on the tweet to expand it and then deleting it.

Prevention

To avoid falling for phishing scams, always check the address bar of the browser or URL. Most try to use a URL similar to the site they are trying to imitate. Therefore, check carefully. Avoid phishing, malware, and viruses by examining short URLs before visiting them. Find out where links really take you by expanding those pesky shortened URLs with CheckShortURL. Also, it is always best to go to the main website itself. In addition, ignore such message as others are spreading rumors about you since it is most likely fake and the account sending the message is compromised. It is also a good idea to keep an up to date AntiVirus on your computer, regardless of your operating system; yes, Apple Macs can get viruses too (see my list of blog posts debunking that myth).

Tech for University

Source: Wikipedia by Ryan at UTSA Libraries

Now that you're in University, you might be wondering what new tech you might need.  In the run-up to University, big store pushing ‘back to school’ tech sales in our face.  You might see PCWorld having big banners advertising £100 discount off the latest computers or £50 rebate with the purchase of a certain brand of computer.  And it may seem that technology may be embedded into our daily lives, but I’m here to guide you through the maze of tech buying.  I will help you stay cool and within budget.

Computers


It is no arguing that computers and students go hand in hand.  Almost all of the lecture notes in the upcoming weeks can be found on Blackboard (Blackboard.swan.ac.uk) and most of you will be writing essay papers on computers to be printed out later.


Today, there are so many laptops and so much competition in the market you should have no problem finding one that suits your needs at a reasonable price.  


Four of the most important hardware specs to look at when buying a new Windows PC are the processor, memory, graphics card, and storage.


Hardware components

Processor


Computer processors come a myriad of models with a confusing number-based model like the Core i7, i5, etc.  For everyday tasks, Core i3 or i5 (or AMD equivalent) would suit your need.  For the gamers out there, if your budget suits, you could go for the Core i7 processor, depending on the need of the game you’re playing since not all games are built equal.


Random Access Memory (RAM)

Ram is your computer’s ‘working area.’  The more RAM you have, the more concurrent tasks your computer can perform at the same time.  An example would be working on an essay while playing music in the background.  For a headache-less experience, look for a laptop around 4 GBs of RAM or more.


Storage


Your computer storage is like a filing cabinet.  The more storage you have, the more you can store.  Music, videos, pictures, and university work all use up storage.  Long ago, if you store a lot of things on your computer, just get a computer with more storage options.


However, nowadays, there are tons of cloud storage option available.  Google Drive and Microsoft OneDrive allow you to save your work online and then access them anywhere.  So essentially you might not need that big a storage that a salesperson might be pushing at you.


In addition, adding to the mix are the two main types of hard drives HHDs and SSDs.  HHD or hard-disk drives are the traditional platter-based hard drive of magnetic tapes that store your files.  As you can imagine, it takes time for the platter to ‘spin’ to the right place where the file is stored.  Therefore, SSDs or solid-state drives were created.  Unlike HHDs, SSDs have no moving parts; therefore, data can be accessed instantly with little to no delay.  It allows your computer more speed and efficiency.  A drawback of SSDs is the cost.  SSDs are more expensive per GB.  But they might be worth your attention if you don’t store a lot of things on your computer.  And even if you do, hybrid-drives are an alternative compromise, storing essential software files on the SSD while regular files sit on the larger HHDs.


Graphics card


A graphics card, as the name suggests, is hardware that is used to convert the 1’s and 0’s into an image that you can see.  Cheap laptops often have the graphics processor built into the circuit board or even into the main processor chip.  These might be perfectly fine for everyday use, but for the power-hungry gamer out there, it might be worth investing in a dedicated graphics card for maximum performance.


In addition to the hardware specs, an important aspect of a computer is the operating system.  Below are three of the most popular computer system.


Operating systems


Mac OS X

It is often the go-to computer in movie University where all students are seen carrying one of these shiny slick aluminum machines.  But it is no arguing that they are quite pricey.  But if Apple is your liking you can grab a cheap bargain by going to the Apple Student store and buying a new device from there.  As of the writing of this blog, Apple is offering 15% off selected iMac lines.


Microsoft Windows OS




 Microsoft Windows is the king of the operating system.  It is the de facto operating system of choice by manufacturers.

There are tons of computer buying guide out there, but ultimately the decision rest with you with choosing a computer that fit your needs.  Like the Mac OS X mention above, many of the Windows manufacturers are offering ‘student stores’ that offer discounts on the popular range of PCs.  One example is the HP student store.

Google Chrome OS


Google Chromebooks are the newcomers on the block.  They are powered by Chrome OS, a brand new operating system built by Google from the ground up with a view toward the web. If you have used a Chrome browser, you have pretty much used the operating system.  Chrome OS is a browser OS, and it is lightweight and require very little resource.  Updates install on the background and simply require a reboot to start. In addition, Chrome OS takes mere seconds (around 7 in my tests) from pressing the power button to being on the web.

Now you might be asking what use is a web browser when you can’t do anything offline.  Thanks to the Microsoft Scroogled smear campaign attempt to discredit Chrome OS, Chrome OS is painted in a negative light that it is basically a paperweight since it can’t do things that a ‘real PC’ can do.  Well, don’t fret.  Word processing? No problem. Two solutions are available: Google docs or Microsoft Office online. Music your thing? No biggy. I'm pretty sure most of you are on YouTube anyway. Plus you can upload your music to Google Play Music online and it will work on any PC.  Anything you do on a traditional computer there is an equivalent application on the web.

Also, nowadays, Chromebooks can run Linux apps.  And there's usually a Linux equivalent of any Windows software you want.

For an in-depth review, please see my article on Chromebooks.


Cell Phones


It seems that cellphones are all the craze nowadays, with the top of the line Samsung Galaxy S10+ or iPhone X seen as ‘cool’ and hip.  But do you really need those phones or that many minutes? Shop around and find the best deal to suit your needs.  You may find out you don’t actually need that many minutes offered on the plan.


In addition, you could try getting last year's model or the year before that.  They are just as capable.  How much do you need the new iPhone X or the new Samsung Galaxy S10?  You could easily grab a bargain on the old iPhone 5 or the old Galaxy S4 or S5.  Last year’s flagship models are just as capable as this year’s model for a fraction of the cost.  In addition, there are tons of cheaper alternative like Motorola Moto X Play (from £21.99 per month (EE) or £249.99 sim free at Carphone Warehouse) or the Moto G (from £16.99 per month (EE) or £159.99 sim free at Carphone Warehouse).


Tablets

Tablets are perhaps the least appreciated technology. With phones getting bigger and computers getting smaller, tablets are slowly getting crowded out of the market.  But tablets are great for taking notes.  I have one and frequently use that to scribble on lecture slides with any notes that I want to add during lectures.  However, but you don’t need to go purchase a new tablet just for University. You could always search eBay for a good second-hand tablet


There are many tablets out there, but I personally recommend a tablet that has a stylus, which is good for taking notes.


Office software


Now we move onto the software.  I’m sure many of you are familiar with Microsoft Office for writing documents.  But if you don’t have that, don’t fret.  Swansea University provides a free copy of Office ProPlus for the PC (inc. Word, Excel, PowerPoint, Access, Publisher, etc.) or Microsoft Office for Apple Mac (inc. Word, Excel, and PowerPoint).  To download a copy go to https://myuni.swansea.ac.uk/it-services/software-enquiry/. There may be a similar deal offered by your local University.


In addition, there are tons of free Microsoft office alternative out there.  One of them is Google Docs, which is an online document writer that is just as good as Microsoft Office.  One advantage of Google docs is that it allows easy collaboration of the document with other students.  Just click “share” on the document and then type in the email.  Then all your friends or group partner can type in the same document in real-time.  There’s even a Google chat to discuss ideas.


Another free alternative is Openoffice or Microsoft Office Online, which is a watered-down Office provided online by Microsoft.  It is quite similar to Google docs.

In summary, you don’t have to spend big bucks and go broke buying all the necessary techs for university.  And wherever the road may take you, have fun and enjoy your time at your chosen university!

What to do if you're in debt?

Students are well known for being poor and cash-strapped and loan companies know this.  Therefore, some companies, such as Smart-pig, target students promising a quick and easy way to borrow money to cover shortfalls in the budget.  These types of loans are informally known as "payday loans" as they are aimed at providing money between paydays.  It is typically expected that the debt is repaid the next payday.

However, don't be tempted into taking out a loan with these companies.  Smart-pig charges 0.8% A DAY capping the interest at 50% of the original loan (according to the website).  Wonga, the infamous payday company that had recently gone bankrupt, charges an interest rate of 292%.  Therefore, you can quickly get into more financial problems if you have used one of those short-term loan companies.

An even worse source of money is a loan shark.  These illegal lenders target low-income people and charge high-interest rates.  For example, according to the Money Advice Service, one woman who borrowed £500 ended up repaying £88,000.  These lenders will seem friendly at first, but unlike payday loans, these loan sharks will often harass you or resort to violence if you get behind on your payment.   In addition, they might pressure you to borrow more money to cover the original loan.  As a result, you might end up in a spiral of debt that you can never repay.




A payday loan or a loan shark should never be relied upon if you are short of cash.  What you can do instead, is talk to your parents or friends and see if they can help you out with your financial issues.  I'm sure they are more than willing to help you out.

In addition, as a Swansea University student, you have a comprehensive team to support your financial issues.  Your first point of call should be Money@CampusLife team which can give you advice about keeping your finance in check.  In addition, the Money@CampusLife team can advise you about the various Hardship Funds available to help students who are struggling with their finances.

If you're not a Swansea University student, contact your local student union for directions to the relevant team at your university.

If you are not a University student, you can ask the Citizens Advice Bureau or the Money Advice Service for advice regarding debts.

You should never feel that you're alone. There are people there to support you.



Tech tips for students


Hey.  I'm sure going to University for the first time is both exciting and scary.  Here are some tech tips for you.

Get your own router

Unless you like random people blasting music on your Google Home or Amazon Echo devices, I recommend getting your own router. Depending on your budget, a cheapo router from Amazon could do the deed but if you plan on holding on your router for longer than 3 years, maybe it would be worth investing in a good brand name router. Look at reviews to decide which router is best for you.

Our rooms at Swansea University Bay Campus have an ethernet to plug in a router but this can vary depending on the accommodation you are moving in to.

Also, a router allows you to form a local area network in your room so that you can connect network devices like printers, Chromecasts, etc.

Getting some oomph from library computers (specifically for Swansea Students but your mileage may vary)

The computers at Swansea University have a hidden "C:" drive that is not normally seen. All files you save are stored in a network drive located at Singleton Campus. So running large simulations or CAD software from it can be slow and laggy. Therefore, I would save your files on the local C: drive and copy it off to a USB thumb drive or external hard drive once the simulation is done

Also, by default, you get around 2 GB of space allotted but you can ask nicely to have it expanded to 4 GB. Just email "engineeringit@swansea.ac.uk" with your request or visit room Engineering Central C105 (Engineering Central, C Block, 1st floor, Room 105).

Other Universities may have a similar configuration set up.

Make sure to match the version of software installed on the library computer

Most engineering software is not backward compatible. That means that files made with a newer version won't run on older versions. Software with known backward incompatibility:
  • Solidworks
    For example, files made with version 2018 won't run on version 2017.
  • Ansys
    For example, files made with version 19.2 won't run on version 18.2.
Therefore, always check the version installed on your university computers before downloading and installing it on your own PC. There's nothing worse than having to re-do the work because the file you send to your groupmate won't open on their computer.

If you feel I'm missing any tips, be sure to leave a comment on this post.
