Algebra was invented in Persia nearly one thousand years ago. It is one of the fundamental branches of mathematics and its theories are applied to many industries. Algebra ranges from solving for x to complex formulas that leave one scratching their head. If you are interested in learning linear algebra, then you should visit Sheldon Axler’s Web site. Along with an apparent love for his pet cat, Axler is a professor of mathematics at San Francisco State University.
On his Web site, Axler lists the various mathematics books he has written and contributed too. It is an impressive bibliography and his newest book is titled, Linear Algebra Abridged. He describes the book as:
Linear Algebra Abridged is generated from Linear Algebra Done Right (third edition) by excluding all proofs, examples, and exercises, along with most comments. Learning linear algebra without proofs, examples, and exercises is probably impossible. Thus this abridged version should not substitute for the full book. However, this abridged version may be useful to students seeking to review the statements of the main results of linear algebra.
Algebra can be difficult, but as Axler wrote above learning linear algebra without proofs is near impossible. However, if you have a grounded understanding of algebra and are simply looking to brush up or study linear principles without spending a sizable chunk on the textbook, then this is a great asset. The book is free to download from Axler’s Web site, along with information on how to access the regular textbook.

It is inevitable in college that you were forced to write an essay. Writing an essay usually requires the citation of various sources from scholarly journals. As you perused the academic articles, the thought probably crossed your mind: who ever reads this stuff? Smithsonian Magazine tells us who in the article, “Academics Write Papers Arguing Over How Many People Read (And Cite) Their Papers.” In other words, themselves.
Academic articles are read mostly by their authors, journal editors, and the study’s author write, and students forced to cite them for assignments. In perfect scholarly fashion, many academics do not believe that their work has a limited scope. So what do they do? They decided to write about it and have done so for twenty years.
Most academics are not surprised that most written works go unread. The common belief is that it is better to publish something rather than nothing and it could also be a requirement to keep their position. As they are prone to do, academics complain about the numbers and their accuracy:
It seems like this should be an easy question to answer: all you have to do is count the number of citations each paper has. But it’s harder than you might think. There are entire papers themselves dedicated to figuring out how to do this efficiently and accurately. The point of the 2007 paper wasn’t to assert that 50 percent of studies are unread. It was actually about citation analysis and the ways that the internet is letting academics see more accurately who is reading and citing their papers. “Since the turn of the century, dozens of databases such as Scopus and Google Scholar have appeared, which allow the citation patterns of academic papers to be studied with unprecedented speed and ease,” the paper’s authors wrote.
Academics always need something to argue about, no matter how miniscule the topic. This particular article concludes on the note that someone should get the number straight so academics can move onto to another item to argue about. Going back to the original thought a student forced to write an essay with citations also probably thought: the reason this stuff does not get read is because they are so boring.

The lawless domain just got murkier. Apart from illegal firearms, passports, drugs and hitmen, you now can procure a verifiable college degree or diploma on Dark Web.
Cyber criminals have created a digital marketplace where unscrupulous students can
purchase or gain information necessary to provide them with unfair and illegal
academic credentials and advantages.
The certificates for these academic credentials are near perfect. But what makes this cybercrime more dangerous is the fact that hackers also manipulate the institution records to make the fake credential genuine.
The article ADDS:
A flourishing market for hackers who would target universities in order to change
grades and remove academic admonishments
This means that under and completely non-performing students undertaking an educational course need not worry about low grades or absenteeism. Just pay the hackers and you have a perfectly legal degree that you can show the world. And the cost of all these? Just $500-$1000.
What makes this particular aspect of Dark Web horrifying interesting is the fact that anyone who procures such illegitimate degree can enter mainstream job market with perfect ease and no student debt.

Think Amazon is the only outfit which understands the concept of strategic pricing, bundling, and free services? Google has decided to emulate such notable marketing outfits as ReedElsevier’s LexisNexis and offering colleges a real deal for use of for-fee online services. Who would have thought that Google would emulate LexisNexis’ law school strategy?
I read “Google Offers Free Cloud Access to Colleges, Plays Catch Up to Amazon, Microsoft.” I reported that a mid tier consulting firm anointed Microsoft as the Big Dog in cloud computing. Even in Harrod’s Creek, folks know that Amazon is at least in the cloud computing kennel with the Softies.
According to the write up:
Google in June announced an education grant offering free credits for its cloud platform, with no credit card required, unlimited access to its suite of tools and training resources. Amazon and Microsoft’s cloud services both offer education programs, and now Google Cloud wants a part in shaping future computer scientists — and probably whatever they come up with using the tool.
The write up points out:
Amazon and Microsoft’s cloud services offer an education partnership in free trials or discounted pricing. For the time being, Microsoft Azure’s education program is not taking new applications and “oversubscribed,” the website reads. Amazon Web Services has an online application for its education program for teachers and students to get accounts, and Google is accepting applications from faculty members.
How does one avail oneself of these free services. Sign up for a class and hope that your course “Big Band Music from the 1940’s” qualifies you for free cloud stuff.

The article on Inside HPC titled IBM Partners with University of Aberdeen to Drive Cognitive Computing illustrates the circumstances of the first Scottish university partnership with IBM. IBM has been collecting goodwill and potential data analysts from US colleges lately, so it is no surprise that this endeavor has been sent abroad. The article details,
In June 2015, the UK government unveiled plans for a £313 million partnership with IBM to boost big data research in the UK. Following an initial investment of £113 million to expand the Hartree Centre at Daresbury over the next five years, IBM also agreed to provide further support to the project with a package of technology and onsite expertise worth up to £200 million. This included 24 IBM researchers, stationed at the Hartree Centre, to work side-by-side with existing researchers.
The University of Aberdeen will begin by administering the IBM cognitive computing technology in computer science courses in addition to ongoing academic research with Watson. In a sense, the students exposed to Watson in college are being trained to seek jobs in the industry, for IBM. They will have insider experience and goodwill toward the company. It really is one of the largest nets cast for prospective job applicants in industry history.

Does your business need a mentor? How about any students or budding entrepreneurs you know? Such a guide can be invaluable, especially to a small business, but Google and Bing may not be the best places to pose that query. Business magazine Inc. has rounded up “Ten Top Platforms for Finding a Mentor in 22016.” Writer John Boitnott introduces the list:
“Many startup founders have learned that by working with a mentor, they enjoy a collaboration through which they can learn and grow. They usually also gain access to a much more experienced entrepreneur’s extensive network, which can help as they seek funding or gather resources. For students, mentors can provide the insight they need as they make decisions about their future. One of the biggest problems entrepreneurs and students have, however, is finding a good mentor when their professional networks are limited. Fortunately, technology has come up with an answer. Here are nine great platforms helping to connect mentors and mentees in 2016.”
Boitnott lists the following mentor-discovery resources: Music platform Envelop offers workshops for performers and listeners. Mogul focuses on helping female entrepreneurs via a 27/7 advice hotline. From within classrooms, iCouldBe connects high-school students to potential mentors. Also for high-school students, iMentor is specifically active in low-income communities. MentorNet works to support STEM students through a community of dedicated mentors, while the free, U.K.-based Horse’s Mouth supports a loosely-organized platform where participants share ideas. Also free, Find a Mentor matches potential protégés with adult mentors. SCORE supplies tools like workshops and document templates for small businesses. Cloud-based MentorCity serves entrepreneurs, students, and nonprofits, and it maintains a free online registry where mentors can match their skill sets to the needs of inquiring minds.
Who knew so much professional guidance was out there, made possible by today’s technology, and much of it for free? For more information on each entry, see the full article.

The article on TheNextWeb titled Teenagers Have Built a Summary App that Could Help Students Ace Exams might be difficult to read over the sound of a million teachers weeping into their syllabi. It’s no shock that students hate to read, and there is even some cause for alarm over the sheer amount of reading that some graduate students are expected to complete. But for middle schoolers, high schoolers, and even undergrads in college, there is a growing concern about the average reading comprehension level. This new app can only make matters worse by removing a student’s incentive to absorb the material and decide for themselves what is important. The article describes the app,
“Available for iOS, Summize is an intelligent summary generator that will automatically recap the contents of any textbook page (or news article) you take a photo of with your smartphone. The app also supports concept, keyword and bias analysis, which breaks down the summaries to make them more accessible. With this feature, users can easily isolate concepts and keywords from the rest of the text to focus precisely on the material that matters the most to them.”
There is nothing wrong with any of this if it is really about time management instead of supporting illiteracy and lazy study habits. This app is the result of the efforts of an 18-year-old Rami Ghanem using optical character recognition software. A product of the era of No Child Left Behind, not coincidentally, exposed to years of teaching to the test and forgetting the lesson, of rote memorization in favor of analysis and understanding. Yes, with Summize, little Jimmy might ace the test. But shouldn’t an education be more than talking point mcnuggets?

Is big data good only for the hard sciences, or does it have something to offer the humanities? Writer Marcus A Banks thinks it does, as he states in, “Challenging the Print Paradigm: Web-Powered Scholarship is Set to Advance the Creation and Distribution of Research” at the Impact Blog (a project of the London School of Economics and Political Science). Banks suggests that data analysis can lead to a better understanding of, for example, how the perception of certain historical events have evolved over time. He goes on to explain what the literary community has to gain by moving forward:
“Despite my confidence in data mining I worry that our containers for scholarly works — ‘papers,’ ‘monographs’ — are anachronistic. When scholarship could only be expressed in print, on paper, these vessels made perfect sense. Today we have PDFs, which are surely a more efficient distribution mechanism than mailing print volumes to be placed onto library shelves. Nonetheless, PDFs reinforce the idea that scholarship must be portioned into discrete units, when the truth is that the best scholarship is sprawling, unbounded and mutable. The Web is flexible enough to facilitate this, in a way that print could never do. A print piece is necessarily reductive, while Web-oriented scholarship can be as capacious as required.
“To date, though, we still think in terms of print antecedents. This is not surprising, given that the Web is the merest of infants in historical terms. So we find that most advocacy surrounding open access publishing has been about increasing access to the PDFs of research articles. I am in complete support of this cause, especially when these articles report upon publicly or philanthropically funded research. Nonetheless, this feels narrow, quite modest. Text mining across a large swath of PDFs would yield useful insights, for sure. But this is not ‘data mining’ in the maximal sense of analyzing every aspect of a scholarly endeavor, even those that cannot easily be captured in print.”
Banks does note that a cautious approach to such fundamental change is warranted, citing the development of the data paper in 2011 as an example. He also mentions Scholarly HTML, a project that hopes to evolve into a formal W3C standard, and the Content Mine, a project aiming to glean 100 million facts from published research papers. The sky is the limit, Banks indicates, when it comes to Web-powered scholarship.

Deep learning is another bit of technical jargon floating around and it is tied to artificial intelligence. We know that artificial intelligence is the process of replicating human thought patterns and actions through computer software. Deep learning is…well, what specifically? To get a primer on what deep learning is as well as it’s many applications check out “Deep Learning: An MIT Press Book” by Ian Goodfellow, Yoshua Bengio, and Aaron Courville.
Here is how the Deeping Learning book is described:
“The Deep Learning textbook is a resource intended to help students and practitioners enter the field of machine learning in general and deep learning in particular. The online version of the book is now complete and will remain available online for free. The print version will be available for sale soon.”
This is a fantastic resource to take advantage of. MIT is one of the leading technical schools in the nation, if not the world, and the information that is sponsored by them is more than guaranteed to round out your deep learning foundation. Also it is free, which cannot be beaten. Here is how the book explains the goal of machine learning:
“This book is about a solution to these more intuitive problems. This solution is to allow computers to learn from experience and understand the world in terms of a hierarchy of concepts, with each concept de?ned in terms of its relation to simpler concepts. By gathering knowledge from experience, this approach avoids the need for human operators to formally specify all of the knowledge that the computer needs.”
If you have time take a detour and read the book, or if you want to save time there is always Wikipedia.

The Dark Web and deep web can often get misidentified and confused by readers. To take a step back, Trans Union’s blog offers a brief read called, The Dark Web & Your Data: Facts to Know, that helpfully addresses some basic information on these topics. First, a definition of the Dark Web: sites accessible only when a physical computer’s unique IP address is hidden on multiple levels. Specific software is needed to access the Dark Web because that software is needed to encrypt the machine’s IP address. The article continues,
“Certain software programs allow the IP address to be hidden, which provides anonymity as to where, or by whom, the site is hosted. The anonymous nature of the dark web makes it a haven for online criminals selling illegal products and services, as well as a marketplace for stolen data. The dark web is often confused with the “deep web,” the latter of which makes up about 90 percent of the Internet. The deep web consists of sites not reachable by standard search engines, including encrypted networks or password-protected sites like email accounts. The dark web also exists within this space and accounts for approximately less than 1 percent of web content.”
For those not reading news about the Dark Web every day, this seems like a fine piece to help brush up on cybersecurity concerns relevant at the individual user level. Trans Union is on the pulse in educating their clients as banks are an evergreen target for cybercrime and security breaches. It seems the message from this posting to clients can be interpreted as one of the “good luck” variety.
