Can a virtual assistant do video editing?
Big YES for this question. Running your own business, it can be a struggle to find enough hours in the day to get everything done. Taking care of everything from customer relations to manufacturing and sales, as well as everything else involved, can leave you physically drained. So when a task such as editing a video presents itself, how do you find the time to get it done? Not only that,but what happens if you don’t possess the necessary skills to piece everything together in the professional manner it deserves? All materials that are representing your brand need to be top quality, so you need a skilled professional backed by experience using various software to get it done right.Virtual assistant can do many different task because they are professionally trained to do different task for their clients I recommend using a site called 24 Task | Home Page which I have used to hire VA’s for the past several years. The beauty of using a freelancer platform is that they will track hours and screenshot what your VA’s have been doing. Plus, they manage payment processing
Which PDF converter does Google Chrome use?

Typically, the HTML file includes associations with other files that either appear on the web page or govern how it looks or works.When you convert a web page to PDF, the HTML file and all associated files—such as JPEG images, Writable Pdf / FLA files, cascading style sheets, text files, image maps, and forms—are included in the conversion process.The resulting PDF behaves much like the original web page. For example, the images, links, image maps, and most media files appear and function normally within the PDF. (Animated GIF files appear as still images, showing the last frame of the animation.)Also, the PDF functions like any other PDF.

What is mapfiles in hadoop?
MapFile:The MapFile , in reality is a directory that contains two SequenceFiles: the data file "/data" and the index file "/index". The MapFile allows us to append the sorted key/value pairs and it stores the key and the offset in the index. This allows for a fast lookup, as instead of scanning all the records till a key is found, we scan the index, which has lesser entries. After finding the block, we can access our actual file.Writing A MapFileTo write a MapFile, create an instance of MapFile.Writer and call the append method, just like in SequenceFile. Keys must be instances of WritableComparable and values must be Writable, unlike a SequenceFile, where we can have any serialization framework.Reading A MapFileTo read the entries of a MapFile, we create a MapFile.Reader and call the next method till a false is returned, indicating an end of file.The get method can be used for random access lookup. If a value is returned, the entry was found, if null is returned, no value exists for that particular key.In order to prevent a MapFile's index to take up a lot of memory, we can use the setting property to load only a fraction of the index keys into the memory. If the value of this setting is 1, it means skip one key for every key in the index, and so on.PDF Download: Most Recent Hadoop Topics
Considering the ease of reading .epub .mobi or .azw3 formats on electronic media, why aren't technical books these days published in such formats instead of the usual PDF?
Sometimes you need several books open (and pages marked) to figure something out. If you relied on e-Readers, you’d have to have as many e-Readers as you did books. My e-Reader also has a significantly smaller ‘page’ - and I’m not just talking the physical dimension, I’m referring to how many lines are displayed. Once again, this is a limiting factor.In my experience, technical books are not referred to in a serial fashion like you read a novel, it is more random, skipping back and forth from one book to another, from one page to another. e-Readers simply don’t work very well in that context.
Which is better for reading ebooks: Kindle or iPad? Which overall reading experience is better? How do the experiences compare?
I read Kindle books on Kindle, iPod Touch, iPhone 4, Droid X and iPad. If I'm going to sit down and read for a long stretch, I definitely prefer the Kindle (I was a beta user of the original Kindle and have the latest). The iPad is too heavy to read comfortably. I've never used the Kindle DX but have heard the same complaints about that device. The Kindle 2 or 3 is the ideal size. can be held with one hand comfortably. Easy on the eyes. Very readable in direct sunlight.Reading on iPad (or any other back lit device) is better in low light. I use if often before going to bed with the lights off so that the light doesn't bother my wife. That's at most about 30 minutes of reading before I start dozing off. At night, I'm more likely to read on the smaller iPod Touch than the iPad. At $139 for the WiFi version of the new Kindle, I'd recommend it highly, even if you have an iPad. I would never buy books on iBooks if I can get it on Kindle. It works across all of my devices and Whisper Sync lets me pick up where I left off on any of my devices. Most people will have a Smart Phone and I'm sure Kindle will have an app for every major phone platform as well as PC and Mac. Not sure if iBooks will keep up. My entire library going forward will be on the cloud and can be accessed using any device I own. That's pretty compelling and will keep me going back to Amazon, even if I don't read all the time on a Kindle device. If Apple ever comes out with a 5 or 7 inch iPad, it could be compelling as a Kindle replacement. I don't really mind the backlight strain on my eyes. What I have a problem with is the size/weight of the 10" iPad compared to the much slimmer and lighter Kindle.
What is the worst computer security mistake an average user can make?
Assuming they are not, and could not be, the victim of a cyber-attack.The truth is everyone is a target, whether by name or by being in the wrong place at the wrong time. Even if you think you have nothing of value, you are wrong.Ex: Your dormant PayPal account is valuable to someone who wants to launder stolen money. Once discovered, your account ends up frozen.Ex: Your insurance policy, along with your personal information, can be used to file fraudulent claims, which depletes your coverage.Ex: Your idle CPU time is valuable to someone who wants to mine for bitcoins, but you get stuck with a slow computer.
Can computer viruses be spread through email?
Yes. Generally from attachments. It's how most people get viruses.Here's how it works, for one I analysed recently:Joe gets an email "Dear joe, please pay the attached invoice for $948.45". He gets lots of invoices, it's his job. There's an attachment, a zipfile "". He opens the zipfile, sees a file "invoice". It's actually "invoice.js", but Windows hides extensions, and has a funny icon. It's not an icon for a JPEG or a PDF, but it's not a skull-and-crossbones. He opens it. No prompts, no warnings. It's a javascript file, which in Windows is passed to Internet Explorer (even if the user prefers another browser). IE silently in the background goes online and downloads an executable file from a recently created website, then transfers control to the executable. Which is a cryptolocker virus, which proceeds to encrypt files both locally and to writable network shares. There is no antivirus warning for either the script arriving in email or for the script running, or the executable, because they are both new variants that will not be in the antivirus databases for some 14-odd hours, if not longer. One one Windows variant I tested, there was no prompt at all. On another, a popup "do you want to run this program?".Now, weeks later, it's in most antivirus databases and in Windows Defender. The infected email now would never make it onsite. The website is probably in a list of "malicious websites", but it's gone offline anyway.For that 14-hour window, the only thing that could have protected Joe was his own instincts. He might have been suspicious that it said "Dear joe" rather than "Dear Joe Bloggs" or "Dear Joe" (his email address is ''). Or he might have been suspicious that it does not say in the message what company it is from. But he probably gets the odd scanned paper invoice like that from "a xerox scanner", at least internally to his workplace, and so it may not be as suspicious to him as to, say, a teen who has never received an invoice in her life.
How does FluidInfo compare to Factual?
Hi. Thanks for the question. It's a good one, and one of my favorites :-) We're more often asked to compare Fluidinfo to things that are much less unrelated. The Factual comparison is much more interesting. Here are some points without going into much detail.Fluidinfo has a unique object for everything, similar to the way that Wikipedia has a single page for everything. With Wikipedia the unique identifier of each thing is its URL. In Fluidinfo it's easiest to think of the 'about' tag (whose values are unique across the system) as being the unique identifier, each object also has a uniquer URL too.  Just as with Wikipedia, if you ask Fluidinfo for the object for something and that object doesn't exist yet, it is created on the fly and is writable. E.g. Fluidinfo has an object for the URL of this page "How does FluidInfo compare to Factual?" and I've just added a terrycojones/rating tag to it, with a value of 8.  You can see a visualization of it here if you like:  Here's an article about Fluidinfo having an object for every Sudoku puzzle and for every MD5 sum, Factual are not trying to provide this object for everything.  So that's a very big difference.---A second is in data types. I don't know the details of Factual, so someone else will need to give more information, but Fluidinfo's tags on an object can be of pretty much any type. They can be simple things like numbers, strings, sets of stings, Boolean, and null. But they can also be PDF docs, audio/video, HTML, Javascript, or anything else you like (you get to specify a MIME type for each tag, and it's returned when you do a GET). So it's possible to host web applications (HTML, JS, CSS etc) in Fluidinfo. From what I understand, Factual is more focused on data that can be displayed spreadsheet-like in a grid. But their docs aren't (or at least weren't) too clear on that - which may have changed.---Next, reputation and trust. Factual are setting themselves up as a trusted authority. They're basically saying "you can trust this data because we've stamped our name on it, and we've used algorithms to establish that out of the various opinions about what value something might have, we've chosen the one that seems right." So, as you can tell from the name, Factual are interested in facts. Fluidinfo, on the other hand, lets reputation and trust be attached to data via domain names. If you see an on a book in Fluidinfo, you know it's official because only Amazon can use the name inside Fluidinfo. Fluidinfo itself doesn't care about facts, it's more like a storage system in this respect.  If you put data into Fluidinfo, it's going to be there when you ask for it because it's yours and you can assert whatever you like (even if it's wrong or inconsistent). If you put data into Factual that they don't agree is factual, it may never appear (see ). The two models are both useful of course, but they're very different and for different audiences.  ---There seem to be quite big differences in the permissions model between Factual and Fluidinfo. I can't comment on them because last I looked (some months ago) the Factual permissions weren't so easy to make out. Fluidinfo has a model in which objects don't have owners but there's a simple but also flexible and powerful permissions model at the level of the tag.---I think it's worth emphasizing in summary that there's something like a philosophical difference between the two.Factual has a strict approach: they're concerned about truth (facts!) and are focused on cleaning data, resolving ambiguities, etc. These are traditional computer science values: be consistent, unambiguous, complete, etc. Fluidinfo is much more cavalier: it doesn't care about those things.  That kind of care can be layered on top for those who want it, but Fluidinfo is more concerned that all players are guaranteed to have a voice, even if it's wrong or inconsistent, etc. This is more evolutionary / biological. It's richer and offers more possibilities (including being totally wrong). The web's problem of being full of conflicting / incomplete / incorrect information isn't a bad problem to have.  Again, things can be layered on top (think Wikipedia disambiguation) and reputation & trust can evolve (domains on data, tags on tags, the system watching itself & knowing what is trusted / useful / related, etc).---I hope that's helpful. I find all this (Factual, Fluidinfo, Wikipedia) extremely interesting, and have spent a long time thinking about these kinds of things. So please feel free to ask more or to mail me:
