chrome 57 will throttle background tabs to save energy


chrome's page visibility api checks tabs after 10 seconds in the background. the new feature will leave tabs playing audio or maintaining websockets or webrtc connections alone, since the api considers them to be in the foreground. however, it minimizes all the tabs the api considers to be in the background unless it's absolutely necessary to run them at full capacity. the chrome team says this new mechanism can lead to 25 percent fewer busy background tabs. since their goal is fully suspend those tabs, though, their work is far from done. chrome 57 has been out for a few days now. you can download it anytime, especially if you're always on the go and would like to limit chrome's impact on your laptop.

can anyone explain the meaning of this icon?


fixed in the next build, thanks.this has been broken for over two and a half years – the close button had the sprite sheet as its background image (a leftover from long ago), but no background-position set because it wasn't actually meant to be sprited anymore.which means that the "×" always had the top-left corner of the sprite sheet in the background. the sprite sheet is different per-site, and on most sites, there's nothing in the top left corner – but on some, as you found, there is.

over 8,000 uber, lyft drivers fail new massachusetts background check


under the new law, which went into effect in january, drivers for ride-hailing companies must undergo a two-part background check, one from the companies and one by the state. out of 70,789 applicants, 8.206 drivers were rejected, according to a state review. hundreds were turned down because they had serious crimes on their record, including violent or sexual offenses. others had drunk or reckless driving offenses. 51 applications came from alleged sex offenders.uber has faced criticism in the past over its handling of background checks. district attorneys in los angeles and san francisco filed a civil suit against the company in 2014, claiming it failed to unearth the criminal records of 25 drivers in those areas. but, both uber and lyft point out that the massachusetts background check

massachusetts' uber, lyft driver reviews spurs other states to tighten backgroun


shocking results of newly mandated background checks in massachusetts for drivers of ride-hailing services like uber and lyft have many advocates and lawmakers calling on other states to follow the bay state’s lead and toughen their own reviews.massachusetts’ new state records review resulted in the banning of more than 8,200 of the state’s almost 71,000 drivers who had already passed background checks conducted by ride-hailing companies.while most of those who failed the state-mandated background check did so because their license had been suspended, they had been licensed to drive for less than three years or they had multiple driving offenses, there were also more than 300 applicants who had felony convictions and 51 who were registered sex offenders.“it’s absolutely terrifyin...






why is there no effective anti-gun lobby in the united states?


the simplest answer is there's no coherent anti-gun argument because the path to achieve what they want involves banning and confiscating all guns.whenever we have a mass shooting in the us (which is what typically sparks these debates), the subject of gun control comes up. but the laws that inevitably come up would do little, if anything, to prevent mass shootings. most of the gun control laws fail because they're aimed at people who have already done bad things. understand, if you want to buy a gun in the us, right now, you must pass a federal background checkwhen an individual goes to a retailer to purchase a firearm, the retailer contacts the fbi to run a background check on each gun purchaser. the fbi checks the national instant criminal background check system (nics) to see if they..






code golf - create a checkbox


2 bytes saved thanks to @tuukkax by using -a%2 instead of a%2*-12 bytes saved thanks to @tuukkax by using a=-aint a=1;void draw(){background(a);}void mousepressed(){a=-a;} the checkbox alternates between being black and white.explanationint a=1; //the variable that contains the state of the checkbox void mousepressed(){a=-a;} //if the mouse is pressed, change the sign of a now there are many other alternatives like using an if-statement to process this, but then it gets weird and constantly changes the background while the mouse is being pressed. i first tried mouse on, but then i would need more conditions and more code that will just end up much more verbose.now for mousepressed() to be called forever (otherwise it would just stop after the program has just started), we need a draw() fun






passports - is it legal to photoshop the background of a visa photo?


speaking specifically about visas for the usa, as far as i can tell, it is not acceptable (it's not illegal, it just means they won't accept the photo).the us department of state's page on photos in visa applications has a section near the bottom, "detailed examples of visa photos", under which there's a tab "digital alterations and retouching" which includes an example that fails because the sitter has red-eye. the note under this photo saysdigitally remove the red eye effect, or retake a photo that does not include the red eye effect. (this is the only digital retouching that is acceptable for passport photos)from which i conclude that recolouring the background is not acceptable. they do give another specific case where someone's made a white background by cropping out the exis...






why espn decided to use a photoshopped version of tiger woods


espn is attempting to defend its usage of an altered tiger woods mugshot during sportscenter on monday. the mugshot from the palm beach county sheriff’s office showed a more disheveled version of woods, with unkempt hair and a greenish background. according to a statement released by espn, the network went with an altered version, picturing woods with a buzzcut, different lighting and a blue background, because the cropping was necessary to fit their “standard template.” “we have utilized a standard template for on-air headshots, which led to the background being dropped for consistency,” espn said. “we will revisit this process to improve it going forward.”send a letter to the editorjoin the conversation:facebooktweet






the internet is collectively confused about a giraffe in this gender reveal vide

running command in background and print output to a file without printing to scr


well, first the syntax you're trying to use should look like this: ./mc.x > test.out 2>&1notice extra & in command you have tried to use. and yes, this way you won't be able to send the program to a background. tl;dr use nohup to accomplish what you want: nohup 2>&1 ./mx.c &this way program would not hang your terminal and send both stdout and stderr to a file named nohup.out.

is the background in this animation black or white? optical illusion baffles red


an optical illusion which shows a series of spinning black and white crosses has prompted a level of online bewilderment not seen since #thedress.as with its viral predecessor, the question at the heart of this illusion is about colour: in this case, is the background black or white?view post on imgur.comthere doesn’t appear to be a correct answer. in fact, some people have questioned whether the image even has a background.the white crosses spin clockwise before the black crosses spin anticlockwise, forming a moving image confusing enough to give redditors headaches.the image, which has been viewed over 4 million times on imgur, was first spotted by digg, who suggested it’s based on “figure-ground organisation”.the term was coined in 1915 by edgar rubin, a psychologist who created...






dnd 5e - can a bard use a greatsword?


as others have noted, taking the college of valor as a 3rd level bard is an 0ption. multiclassing is an option. the weapons master feat is an option. all of those are significant constraints or character development expenses to get one weapon proficiency. they each come with other benefits, of course, but they may not represent what you are trying to do with your character.another option would be to work with your gamemaster on a custom background. your background generally gives you at least two skills and a feature; perhaps your gamemaster would let you substitute greatsword proficiency for one of those, based on your family history.

troubleshooting - can i show two sides of a card in one photo?


ok, since you've asked for creative ways, here we go. place the id card at the left side of the frame, take an under exposed photo with a long shutter time (5 seconds), fire a flash, turn the id card around and place it at the right side of the frame, fire the the flash a second time. we now have both sides of the id card in a single shot without any mirrors. if the flash was located close to the id card and the background is far away, we can even have a nice black background.

united states - background checks for politicians?


in general, the point of electing someone is that the voters are supposed to decide their qualifications. when there are restrictions on who can hold an office, the restrictions tend to be very simple -- are you a citizen, are you a resident of the area, have you been convicted of a felony, etc. some positions might require certain professional qualifications (e.g. requiring a prosecutor to be a licensed lawyer), but again, those are fairly simple yes/no questions and are requirements you'd probably have met long before running for office.at the federal level, the only background requirements are those set out in the constitution. representatives must be at least 25, senators at least 30, presidents at least 35; representatives must have been a citizen for 7 years, senators 9, presidents .

why don't cameras have a precise orientation sensor?


there is always the grueling task of orienting them correctly so that the horizon looks straightsetting the camera level doesn't necessarily make the "horizon" look straight. it works when the background is an ocean or a vast plain, but it's not uncommon to have a mountain or hill or the far shore of a lake in the background. those may not technically be a horizons, they can still make your photo look crooked.beyond that, it's really not a "grueling task" to orient your photo to match the strong vertical or horizontal lines. the viewfinders in most dslrs generally have an array of autofocus points that are visible even when not selected, and you can use several colinear af points as a guide. get into the habit of asking yourself: does the distance between the leftmost af point and t...






supervision - how to supervise a bad phd student


the project is on computational physics/chemistry, and the phd student has a background in chemistry with no prior computational knowledge.

how i was left reeling by sickening racism


spending time with phyll opoku-gyimah left me shocked and appalled but more committed than ever to diversity.i am a fair-skinned woman with a london accent who is understandably assumed to be english through and through. nothing could be further from the truth. my mother was an illegal immigrant of armenian descent, and i was brought up on a council estate in stockwell, south london, often hiding from immigration officials who we feared would drag our mother away to deport her. so, apart from the way i look and sound, my cultural background does not emanate from these islands. and although i acknowledge their privileged upbringing, my children are also mixed race and have also experienced direct racism. i'm telling you this to give you some background as to how - and why - i view the comm.






less gun madness, within reach


"we must do something.” it’s what we always hear in the wake of senseless tragedies like the shooting that left 26 people dead in a texas church, many of them children. then the standoff begins. for democrats, the answer is, often, gun control. what kind, exactly? any and all. casting a wide net, they’ll say “common sense” laws like “expanded background checks” and making it harder for people convicted of domestic violence to get a gun. while federal legislation has lagged, states have passed dozens of small bills which tweak access to guns or ammo. but of course, a background check system already exists and it is already illegal under federal law to possess a firearm if you’ve been convicted of domestic violence. for republicans, the answer is often b...

forms - which is better: a progress bar or a spinner for a long api call


there is a difference between a spinner and a progress indicator: a spinner only communicates just wait,a progress indicator (be it a progress bar or any other form going from 0 to 100%) communicates wait and progress.to communicate progress, exactness it is necessary. this is why those installation progress bars, stopping at 99% are so frustrating. therefore, showing a progress bar in a situation when it is not possible to say when the process will finish is a bad idea.to make the waiting less painful for the user, though, and give him/her some information about the process in the background, you can apply some or both of the following:make the process run in background of user actions - for example, you can show a progress indicator somewhere in e.g. top right corner of the screen while
