9 amazing ways to learn online

szypanther — Tue, 22 Oct 2013 01:57:18 +0000

There is no need to buy a massive set of encyclopedias anymore, as you can learn most things online these days. The trouble is that the internet is filled with terrible amounts of misinformation. So, if you are learning online, you are going to have to find a way of avoiding the 99% of lies and find the 1% of truth. You may do that by looking into trusted resources such as the ones listed below.

TED

This is a place where industry experts come and give a speech or a lecture about their specialty. The lectures apply to almost any academic specialty, although it is better known for its business lectures. It is run by a non-profit organization, and its speakers, students not only from high ranking universities, and topics have made very good college essays in the past. You can find them on TED.com or video websites such as Daily Motion and YouTube.

University Lectures

Many universities now offer some kind of distance learning schemes, but there are also groups that have been set up to spread knowledge for free. There are non-profit groups that universities such as MIT and Berkeley work with in order to give away free video lectures. The lectures are given by institutions with the best universities rankings in the country. Websites such as openculture.com have libraries of free university courses. There are even phone apps that are dedicated to being a library resource for these lectures.

YouTube

This social media network is becoming more and more noisy as it fills with more spam videos and more unskippable advertising, but it does still has its uses, such as the educational programs that it features. The great thing is that you may find educational programs that are not part of an academic course. For example, there are tutorials on how to use the Blender program, where finding tutorials on this elsewhere is near impossible. Do not forget that YouTube is a public access online platform, which means it is going to have its fair share of false information, so keep an eye out and check out their sources before committing!

Wibit.net

This is a website set up by two nerds who give lessons on how to program. They use screen capture technology and their own voices to show you how to write program code. They go from the very basics, including on where to download the software you need to start programming. They go right back from programming in C, up to the most recent programming codes. They even have tutorials on how to make your own Smartphone apps. Other great options, like CodeAcademy.com or Bloc.io, are also available to budding web developers!

Free Books Online

If you have an e-reader, then try a few free book sites before you start buying books. There are a lot of free book directories that allow you to save money by legally downloading books for free. There are a few good free ones, but try e-booksdirectory.com and Gutenberg.org to start with.

BBC Learning

The British Broadcasting Corporation features a wide variety of learning resources, with most of them being based on some sort of video format. You may find their educational resources at bbc.co.uk/learning/. You will find educational resources for both younger and older people. It is good because it has resources for adult learners, teachers, children, and even for parents to help them teach their children.

The Discovery Channel

They have an online resource where they give away some of their content for free at dsc.discovery.com. Remember that this is not a non-profit organization, so they are going to charge you for some things, but do have some free resources on their website. Some may say the same for the History Channel website, but in this writer’s opinion, the History Channel can have shaky content. They often have a confirmation bias, and their reporters have trouble with the “absence of evidence” problem (because the content they produce as a result means that they can talk about the effects of ghosts and aliens without any empirical evidence). Always make sure you take into account the hard facts when learning online!

The Rosetta Project

This is available at rosettaproject.org as is an archive and learning center that helps people learn a new language. It is a global collaboration that has set out to teach people a different language for free. It has 1000 languages in archive that helps people learn a new tongue in a community setting.

Google Scholar

This is a tool that you may find at scholar.google.co.uk, and it does have a big library of academic essays that you may read. Its downfall is that it is so hard to find the pieces that you want. Maybe there is a knack to it and it takes some getting used to, but quite often, you will find relevant pieces by accident rather than by design. Still, it offers free academic content so it is hard to complain when most other websites will charge you to look at academic essays. And, the tool will sometimes help you to site a piece of work too.

Convert Chrome tabs to a list to save memory and your sanity

szypanther — Thu, 14 Mar 2013 02:57:56 +0000

By the end of the workday, my Internet research and wanderings leave me with dozens upon dozens of open tabs. This trail of tabs is confusing to navigate and leaves my laptop feeling sluggish. If you use tabs as temporary bookmarks as I do and use Chrome, I suggest you give OneTab a whirl. This Chrome extension lets you convert all of your open tabs into a list, which lets you reopen each tab individually, restore all at once, or share all as a Web page. Managing a multitude of tabs via OneTab’s lists is easier than juggling the tabs themselves, and it saves memory resources in the process.

After installing OneTab from its Web site or the Chrome Web Store, you’ll see that a button with a small, blue funnel gets added to the right of the URL bar. Clicking the button will close all of your open tabs and open a new Chrome window with these tabs listed as links. I should specify: OneTab grabs all of your nonpinned tabs in a given window; it leaves any pinned tabs as they are, and it doesn’t touch any tabs in additional Chrome windows you may have open. For a subsequent tab-filled Chrome window, clicking OneTab adds its tabs as a new list group above the previous list in the same OneTab window you previously created.

From OneTab’s list, you can click to open an individual tab. Doing so, removes it from the list. Hold down Ctrl (Windows) or Command (Mac) while opening a tab will keep it on the list. You can also click and drag to reorder your lists or move a tab from one group to another.

Above each group on the OneTab window are three links to restore all (in a new window), delete all, or create a Web page to share. The Web page looks no different than the list of links to your tabs on the OneTab window, but it provides a URL at the top, making it a highly convenient way to share a group of Web pages.

At the top-right corner of the OneTab window are a group of links. The first, Bring all tabs into OneTab, closes all (nonpinned) tabs in all of your open Chrome windows and, yes, brings them all into OneTab. The next, Share all as Web page, creates a Web page with all of your tabs, instead of just one group. The Export/Import URLs link takes you to a page of the URLs of all of the tabs saved on OneTab.

I don’t have any use for the import/export feature, and I doubt I’ll use share feature much either. What I like is OneTab’s lists, which give me more information at a glance than a dozen of open tabs do, where most of the time all I can see is a mere favicon. OneTab gives you the favicon along with the title of the site or article. OneTab also keeps a tally of your tabs from one Chrome session to the next, though to open it, you have to move any open tabs to it or open a new Chrome window before clicking the button if you just want to access the tabs you saved to OneTab without adding anything new to it.

OneTab claims to save you up to 95 percent of your precious system memory. With no other applications running, I opened two dozen tabs in Chrome, which used 292.5MB of memory. After depositing these tabs into OpenTab, Chrome was using only 60MB, or nearly an 80 percent reduction. More importantly, my system’s cooling fan stopped spinning and my system no longer felt like it was running in molasses.

Lastly, OneTab is free and completely ad-free.

Do you have a favorite tab management app or system for your favorite browser? Or do you just use Chrome’s Bookmark All Tabs menu option to save a group of tabs? Let me know in the comments below

研究生可以利用免费PodCast来提高英语

szypanther — Fri, 21 Dec 2012 02:17:55 +0000

我知道研究生一般都比较忙，很难拿出大量专门的时间来学习英语。但不管你是想继续科研之路还是到大公司供职，英语又必不可少。以自己为例，阅读文献的能力可能没有什么问题，但写听说的能力就要差很多了，现在出了国，这种体会就越发明显。这里我想谈一些自己对提高英语水平的想法，与广大研究生共勉。

我们提高英语水平的很大一个初衷来源于能够进行流畅的科研交流，不管是参加国际会议还是个人或实验室之间的访问交流。而很多科学杂志就提供了免费的在线音频或视频材料，介绍最新的科研进展与思想。这些材料对于广大的研究生来说非常有用，不仅可以提高英语，还可以了解科研前沿进展与思想，拓展思维引发思考。这包括Science，Nature，Cell的音频PodCast，而如果你更喜欢视频材料，Science Video Portal，Nature Video，Cell PaperFlick给你更多选择。另外上述杂志的子刊还有专门的视频音频材料介绍本学科的最新科研进展与思想。而其他的材料还包括NIH的VideoCasting and PodCasting，包括很多牛人的报告。当然网上还有很多其他免费的音频与视频材料，可以帮助我们提高英语，促进科研。

除了跟科研相关的这些材料，英语学习还是要贴近生活。Friends是大家耳熟能详的经典英语学习材料，这里就不多少。我想说的是研究生们还是可以多听一些比较简单的英语材料，主要是培养自己的英语感觉。我觉得比较好的有English as a second language podcast以及English pronuciation Pod。这些免费PodCast都是比较简单的材料，却是非常有用。例如第二个PodCast每节介绍一个英语发音的技巧或规则，可以使我们的英语发音更像一个native speaker.

当然大家还可以到网上寻找其他适合自己的免费材料来帮助提高英语。另外，所有上面这些材料还有很多其他材料都可以在iTunes里搜索到并订阅播放，非常方便。如果可以打开YouTuBe，上面也有很多很好的视频材料。

最后，一句话，多参加Conference多与人交流才是正道，学以致用为上策。
