Get the Most out of Google Search

Everyone’s familiar with Google search, but not everyone knows that there’s a lot of ways to make their searching methods more effective. After all, the internet’s immense store of information is only useful so much as it can be sorted, and you have a hand in how you trigger what information is deemed important for you to see based on your question. Here are some tips on how to get to the details you want as directly and effectively as possible.

1. If you’re searching for a particular phrase, be sure to include quotation marks in your search. For example, “Here’s Johnny” or “Let them eat cake.” If you can remember most of the phrase but not all of it, put an asterisk where the missing word should be and Google will help you fill it in.

2. If you’re searching for a word with a variety of connotations, you can delete out the irrelevant results by adding a “-” and then putting all the unimportant topics that a search engine might show you. For example, if you wanted to search about red hot chili peppers but not the band, you could try typing “red hot chili peppers -music”

3. Search within a site by inputting the domain name into the service bar like so: “site:theguardian.com” If I wanted to search what CNN had to say about Bernie Sanders I could search “Bernie Sanders site:cnn.com”

site-4. Now say you have a website that you like but you want to see if there are sites similar to that one. All you have to do is write “related” and then enter a colon and the site you like. You loved neopets but need to move on? Try “related:neopets.com”

5. Maybe you have a very specific set of keywords and you only want to see search results that contain every single one of them in their text. simply write “allintext:” and then whichever words you need.

6. Similarly, you can use the “allintitle” function to search words that you specifically want to see in the title of any document that comes up. If you want to search some key words that can occur throughout the document and some that you want in the title, you can do that too using “intitle”  like this: “jerry garcia intitle:death”.

7. Last iteration: use allinurl: for… you get it. For example “allinurl:chimmychonga”.

8. Search for news related to a particular location with “location:”, like you could search “Hillary Clinton location:Iowa”.

choco cake9. Search only for certain file types by adding “filetype:” like “filetype:mp3” or “filetype:pdf”.

10. This one really helps with shopping: search only for results with numbers between a certain range by adding two periods between the lowest and highest number. “used canoe $200..$600”.

Now you’re all grown up and ready to use the Google search engine to the best of yours and its ability. Good luck with all your searching efforts and may you find all the information that you need to fulfill your life and move on to the next step! You can do it, I bet!

Wikipedia Develops Application with AI

The Wikimedia Foundation just released a new service engineered to heighten the accuracy and detail of Wikipedia articles.

Known as the Objective Revision Evaluation Service (ORES), the application uses artificial intelligence (AI) and machine learning (ML) to help Wikipedia editors to identify bad articles with faster speeds and assign them with appropriate scores almost immediately.

Unknown to most Wikipedia users, Wikipedia is actively edited over 500,000 times a day. Volunteer editors must then review those changes, making a lot of man power necessary to keep the site alive and accurate.

oresORES makes it easier for these editors to look through and organize incoming content, identify poor edits and mark them for further scrutiny. Bad edits occur often and range from the deletion of accurate information, addition of inaccurate information, addition of an opinion and addition of an obscenity.

Principal analyst of the Enderle Group Rob Enderle had this to say: “If you’re in the media at all, there’s a chance that someone is going to dislike something that you said and is going to try to damage your Wikipedia page.”

“Low-level AI is really good at identifying patterns and taking prescribed action against the patterns it recognizes. Unless you have a ton more people than Wikipedia has, you’d never be able to keep up with the bad edits. Wikipedia can be more trusted and less likely to be used as a tool to harm somebody [now that it has developed ORES]).”

Wikimedia Senior Research Scientist Aaron Halfaker reiterated the improvement in accuracy and timely edits that ORES is sure to bring: “That allows the editor to review the most likely to be damaging edits first. That can reduce the workload of reviewing edits by about 90 percent.”

So how does it work? ORES is engineered in such a way that it can predict the probability that an edit is damaging by checking in on the before-and-after edits common to all articles that appear on Wikipedia. It then assigns a score to a proposed edit depending on its likelihood of being damaging.

half“Our machine learning model is good enough at sorting those edits by the probability that they’re damaging that you would have to review 10 percent of the incoming edits to know that you caught all of the damaging edits,” continued Halfaker. “Without this tool, you’d have to review all the edits to know you caught all the damaging edits.”

“One of the reasons we want to reduce the workload around quality control is so that editors can spend more of their time working on new article content rather than removing vandalism.”

Despite Wikipedia’s reception of about 12 million hours of volunteer labor a year, they could never get enough volunteers to manage all of the internet vandalism that occurs under their business model in a timely and reliable manner.

Transistors; The Brain Cells of Computers

Like the neurons in human brains, billions of transistors allow for your computer to function. Despite having been invented 50 years ago, little is known about transistors by the general public; here’s a quick rundown to get you up to date.

Transistors are electronic components made of silicon. They can work either as amplifiers or switchers. Let’s start with their work as amplifiers:

Transistors are capable of receiving a small electric current at their input and releasing a much larger electric current at their output. This was first utilized for hearing aids; the transistors allowed for the electric currents generated by tiny microphones worn in the ear to then be converted into much louder sounds played out of a tiny loudspeaker.

Transistors can also function as switches in that the small current entering at the input then switches on a larger current that exits out the output. This is fundamental to how computer circuit boards function; whether or not a transistor is switched on (a current is run through it) can be read as a 0 or a 1, allowing for binary code to be stored via the presence or absence of an electric current. Computer chips contain billions of transistors.

transistor under microscopeBecause there are so many transistors, they have to be extremely tiny and correspond to extremely tiny electrical currents to all fit inside your smartphone. The most advances (and tiny) transistors work by controlling the movements of individual electrons, so they end up being so small you could fit 500 million to two billion on the surface of your fingernail.

You may be wondering how you even make something so small. Here’s how:

As mentioned before, transistors are made out of silicon, which is normally an insulator but in this case has been transformed into a semiconductor by introducing impurities (a process called chemical doping) into the material. The process works by either removing electrons from the silicon and making it more prone to being positively charged (called p-type) or adding electrons to make it more prone to being negatively charged (called n-type).

Once you’ve set up your two types of silicon, you can stick them together and fashion for yourself a kind of silicon sandwich; the junction between the two materials will become normal silicon because the lack and abundance of electrons will start to even out. Now you’ve got a diode (also called a rectifier). Diodes only allow for currents to flow through them in one direction because of the properties of the junction between the two slabs of different-typed silicon.

transistor under micro2To make a junction transistor, you have to actually use three layers of typed silicon, meaning your options are p-n-p or n-p-n. “Once electrical contacts are attached to all three layers, the component will either amplify a current or switch it on or off.

Check out a n-p-n transistor: let’s call the two contacts connected to the n-type silicon the emitter and the collector, and let’s call the contact connected to the p-type the base. Given that a small positive voltage is applied to the base, while the emitter is made negative and the collector is made positive, electrons are going to be pulled from the emitter into the base and then from the base to the collector. That means the transistor is turned on.

Remember that the base current can switch the amplified current on or off. It needs to be outfitted with a positive charge for the current to be amplified on its journey from the emitter to the collector.

How Data is Recovered from a Hard Drive

Most people act like they are immune to data loss. We all have a friend who lost everything when their hard drive crashed, but we assume that we will never go through this process. Unfortunately, statistically we are a lot more vulnerable to these misfortunes than we’d like to think.

guy screaming

A recent study published by Carnegie Melon found that around 20% of mechanical drives fail within their first four years. Just over 5% fail within their first eighteen months. Despite the prevalence of this problem, people don’t back up their data, allowing for data recovery businesses to earn a living (at least until cloud backup becomes the norm).

If you ever find yourself in the dead-hard-drive-with-no-back-up situation, here’s a little information about that service you’re shelling out so much money for:

Operating on a Hard Drive

Once your drive has been diagnosed and handed over to the experts, the recovery process is set in motion. There are many paths to data recovery, but which one the lab team takes depends on what went wrong with your drive.

Many failures are caused by physical damage, meaning data recovery can only be facilitated by physically repairing the drive. Most likely some parts of your drive are going to need to be replaced, which could necessitate ordering them through a third party company or just finding them on eBay.

hard drive surgury

Once the parts have been obtained, the surgery begins. read/write heads, adaptors, and other malfunctioning hard drive components have to be replaced inside a “clean workstation,” which generally involves using a glass case with a fan that blows any dust into the air and another fan that sucks all that air out. This is a crucial piece of equipment to have, because even the tiniest speck of dust that falls on an open hard drive can cause it to malfunction.

If an electronic aspect of the drive is responsible for its failure, technicians may need to use microscopes and specialized soldering equipment to make tiny repairs to your hardware. This process has only become more difficult as technology has gotten smaller and smaller.

Once the drive is functional, it must be imaged. A clone of the drive is created for as many of the drive’s sectors as possible so that lab techs can move through them and focus on whatever necessary data that they contain. Different algorithms can be applied to the sectors depending on how damaged the data is in each one, allowing for the undamaged data to be speedily recovered and the damaged data to be better isolated.

When recovery is finally complete, the data is uploaded to a secure server that is not connected to the internet. Data is returned to the customer on a physical drive and the crisis is over.

So there you have it; if and when you lose all your data, there are things you can do to recover. That said, there are plenty of free cloud services that are probably worth some research.

What Camera Resolution Do I Need?

At the point when shooting photographs with your digital  camera, you can set the camera to give at a camera resolution  intended to address your issues. For photographs you plan to just use on the Internet or send by email, you can give at a lower resolution. In the event that you know you need to print the photograph, you’ll have to give at a higher resolution. Deciding the amount of camera resolution  you’ll at last requirement for a print, relies on upon the print’s measure you need to make. One of the progressions picture takers experience when changing from a film camera to a digital  camera is the different choices in picture quality and resolution  the digital  picture taker has when shooting. Most digital  cameras can shoot no less than five distinct levels of resolution, and some can shoot 10 or more diverse levels.

What it Affects

Despite the fact that the megapixel race has been going ahead since digital  cameras had been developed, the most recent couple of years specifically have seen a tremendous increment in resolution  – we have seen everything from 41 megapixel camera telephones to now 50.6 megapixel full-outline DSLR cameras. It appears like we have as of now come to the hypothetical most extreme for taking care of commotion at high ISOs with the present era sensor innovation, so the makers are currently centering their endeavors in pressing more resolution , while keeping sensor sizes the same to draw more clients to move up to the most recent and most prominent. In this article, I will attempt to clarify some fundamental wording with respect to resolution  and ideally help our peruses in comprehension camera resolution  better.

You may have the most noteworthy resolution  camera available and the best lens that has the capacity exploit the sensor and still wind up with clumsy pictures that need subtle element to make great quality prints. Besides having the capacity to exploit great light and precisely outline/create the scene, you additionally need to have great specialized aptitudes to yield tack sharp pictures. High resolution  cameras basically “increase” everything extraordinarily, whether it is camera shake brought on by poor hand-holding system, screen vibrations starting from the camera, poor centering procedure, flimsy tripod, slight wind or different reasons for obscure in pictures.

So in the event that you choose to climb to a much higher resolution  sensor, you may need to invest some energy learning fitting system to catch pictures. You may need to re-assess your base screen speed for hand-holding, utilization of tripod, utilization of live view for discriminating center, utilization of lenses and ideal openings and that’s just the beginning. In the event that you know you’ll need to make extensive prints constantly, you’ll have to purchase a model that offers a huge greatest resolution . Then again, on the off chance that you know you’ll just need to make incidental, little prints, you can choose a digital  camera that offers a normal measure of resolution , possibly sparing some cash.

Travel Photography for the Digital Photographer
