I have to push to pee: 5 Ways You Could Pee Better > News > Yale Medicine

5 Ways You Could Pee Better > News > Yale Medicine

It’s one of the simplest things you do every day—relieve your bladder. Bathroom visits are so automatic, chances are you’ve not put much thought into whether or not you are urinating in the healthiest way possible. But, there are common bathroom mistakes people make that can lead to unnecessary urinary health issues.

“As urologists, we see many patients with urinary complaints, and sometimes our advice is as simple as educating the patient on healthy voiding habits,” says Yale Medicine urologist Joseph Brito, MD.

Find out if you’re making any of these common urination mistakes.

Mistake 1: Holding it

The sensation of having to “go” usually leads to a trip to the restroom. “But, sometimes life gets in the way—a long car ride, a movie, or simply doing something fun can cause a delay,” says Dr. Brito. Even though it can be inconvenient to stop what you’re doing and use the bathroom, urine-holding may lead to a variety of issues. “Ignoring an urge to urinate may lead to leakage. Or, it’s possible that chronic bladder ‘overstretching’ may lead to new bladder symptoms down the road as people age,” says Leslie Rickey, MD, a Yale Medicine urologist who specializes in women’s pelvic floor problems.

Delaying bathroom breaks is problematic for kids, too. Urologists occasionally see children with recurrent urinary tract infections (UTI) or foul-smelling urine. This is commonly associated with urine-holding, Dr. Brito says. “Encourage your children to take their time in the bathroom, and remind them to take breaks from their activities for it,” he says. “The best advice is to visit the restroom when you feel like you have to go; however, if you have to urinate very frequently, like every hour, you should talk to a physician.” 

Mistake 2: Not emptying fully

When you’re in a rush, incomplete bladder emptying can cause issues far more problematic than taking the extra minute or so in the bathroom. Similar to urine-holding, incomplete bladder emptying allows a reservoir of urine to collect that can potentially cause urinary infections. It can also increase the odds of developing another painful problem—bladder stones, which are salt crystals that sometimes form when urinary concentration or ‘stasis’ develops.

Incomplete emptying isn’t something you are always aware you’re doing, but it’s a good idea to make an effort to ensure you are emptying your bladder, says Dr. Brito. He says this is a particular problem for older men with prostate issues. For them, incomplete bladder emptying can lead to a smaller functional bladder capacity and subsequent urinary frequency and urgency problems. 

“Often as men get older, they will not completely empty their bladder. The problem there is, if your bladder’s full and you empty it halfway and then drink fluids like you normally would, it fills up more quickly,” says Dr. Brito.

Incomplete bladder emptying becomes a problem as men age because of prostate enlargement (also called benign prostate hyperplasia or BPH), a common condition. This can bring a number of symptoms including increased urinary frequency, urgency, and nocturia (nighttime urination), as well as incomplete emptying. “BPH is usually not a dangerous condition,” Dr. Brito says, “but the symptoms can become pretty frustrating and often life-altering.” Though it is rare, these symptoms can also be a sign of something more serious like prostate cancers, and therefore should be discussed with your primary care physician or urologist.  

“Sometimes educating patients to take their time in the bathroom and ensure their bladder is as empty as possible can help,” says Dr. Brito. Other times, patients may need medications or surgery to help the bladder empty better.

Mistake 3: Going too often

One more trip to the bathroom before rushing out the door may seem like smart planning, but it can backfire. The danger is that you can end up “training” the bladder to respond to small volumes, which can lead to overactive bladder symptoms—the sensation of needing to urinate more frequently than is normal, explains Dr. Rickey.

“Going too often at night can also be a problem for men who then can’t fall back to sleep,” says Stanton Honig, MD, director of Male Urology, adding that this condition, called nocturia, can affect quality of life. “If this is bothersome to patients, there are treatment [medications] for it,” says Dr. Honig. 

Other problems can also cause increased urinary frequency, such as an infection along the urinary tract. Therefore, if you find that you need to visit the bathroom far more often than you used to, talk to your primary care physician or urologist. You may need a urinalysis (urine test) to rule out a UTI, as well as to check for blood in the urine (hematuria), which can happen to a small number of people with an overactive bladder who have a bladder tumor, Dr. Brito says. “Blood in the urine is never normal and usually requires further testing to determine its cause,” Dr. Brito says.

Diet can also be a factor for people who notice an uptick on their need to pee. “The bladder is increasingly sensitive as we age,” says Dr. Brito, “and urinary frequency can be due to certain ‘irritative’ foods and beverages such as caffeine, alcohol, carbonated beverages, chocolate, spicy foods, and acidic foods.”

Some people may also visit the bathroom frequently in an attempt to avoid leakage. Although urinary incontinence (an unintended loss of urine) is common and affects a large number of women, it is not something you should just live with,” says Dr. Rickey. “Directed pelvic floor muscle exercises [physical therapy] can resolve these symptoms.” Other treatments such as medications and minimally invasive procedures are available, too, to help with urinary frequency, urgency, and incontinence.

Mistake #4: Pushing

You shouldn’t have to use your muscles to force urine out. A healthy bladder works best if the body just relaxes so that the bladder muscles naturally contract to let the urine flow, rather than using the abdominal muscles to bear down as with a bowel movement.

In men, the need to push urine may be a sign of bladder outlet obstruction, which is commonly due to BPH. “This benign condition causes swelling in the prostate and problems starting the urine stream—or a weak flow,” says Dr. Honig.

Women are less likely to have bladder outlet obstruction, though advanced pelvic organ prolapse can lead to difficulty starting the flow of urine, says Dr. Rickey. The main symptom of prolapse is seeing or feeling a vaginal bulge; it is the result of the pelvic organs (vagina, uterus, bladder, or rectum) descending into the vaginal canal due to weakened pelvic organ muscle support. Having to work hard to push your urine out can also lead to other problems such as hemorrhoids or a worsening of hernia symptoms, explains Dr. Brito.  

If you can’t help but push urine out, see a urologist or primary care doctor to determine if you need medication, specific exercises, or other therapies to address your underlying urinary issue.    

Mistake #5: Not drinking enough water

Many urinary complaints are related to poor hydration.  Generally speaking, if your urine is clear or very light, that’s a sign you are drinking the right amount of water. If your urine is dark yellow or amber, that’s usually a sign of dehydration.

Odor, an “off” color, and (occasionally) the sense of burning while voiding (dysuria) are other signs that might indicate you are not properly hydrated. Not drinking enough water can contribute to UTIs and kidney stones. Concentrated urine can irritate the lining of the bladder, making it more sensitive. It is also more likely to form kidney or bladder stones.

“Many patients ask if drinking alternative fluids will suffice, but many beverages contain high sugar concentrations or caffeine, which can have other health effects,” says Dr. Brito, noting these might make overactive bladder symptoms worse. “Water is the safest option to maintain hydration and keep your kidneys and bladder healthy.”

There are some conditions that can make your urine appear more concentrated even if you are well-hydrated, such as liver problems or hematuria. So, if you are drinking enough water (about 2 quarts a day) but have dark-colored urine, odor, or burning, it’s worth a trip to a urologist, who can evaluate your symptoms more closely. 

“The ability to urinate freely and without difficulty is taken for granted by most people,” says Dr. Brito. So, next time you have to “go,” follow the above advice for better urinary health.

Straining to Urinate? – Healthy Living Center

The need to strain or push in order to urinate can be due to problems with the contractile force of the bladder or problems with obstruction of the bladder outlet and urethra. Failure to empty due to problems with the contractile force of the bladder may be due to nerve-related disorders such as spinal-cord injury, multiple sclerosis, diabetes, and the like. Failure to empty the bladder due to urethral problems is unusual in women. Some causes of obstruction of the bladder outlet in women include prior vaginal or urethral surgeries, rare strictures of the urethra, and, in rare instances, polyps or cancerous lesions.

Urinary symptoms should always be investigated to rule out some of these unusual but serious conditions. In the urologist’s office, an evaluation for these symptoms would typically include a detailed history, physical examination including a vaginal speculum examination, urinalysis, and an ultrasound measurement of bladder volume after voiding. The most important thing that this latter test would show is whether or not the bladder is completely empty. If the bladder empties completely it makes neurological problems unlikely. If the bladder retains a lot of urine, further studies with urodynamics, a bladder-pressure study that assesses the contractility of the bladder muscle, would be appropriate.

Q2. My husband has been taking oxycodone for pain management for eight weeks now. He is currently having trouble urinating. I understand this is from the medication, but what can he do to overcome the problem? Would drinking more liquid help?

— Irene, North Carolina

Oxycodone, as well as other narcotic pain medications, can lead to bladder problems. Your husband’s difficulty urinating may have resulted because the medication interacts with and blocks some of the nerve signals that cause the bladder to contract. If he cannot be switched to a nonnarcotic pain medicine, then additional evaluation is indicated to assess the severity of his urinary problems. Narcotic pain medicines can also lead to constipation, which, if severe, can prevent normal evacuation of the bladder.

It is important to know whether your husband has an underlying predisposition to bladder difficulties. If he has an enlarged prostate, for example, lower urinary tract symptoms that are caused by prostatic enlargement may be exacerbated by a narcotic pain medication. In such cases, additional medication to treat the underlying lower urinary tract symptoms related to prostatic enlargement might improve his situation. It is unlikely that increasing his fluid intake will resolve bladder-emptying problems — this could actually exacerbate them. Any evaluation of a man who has difficulty urinating would also seek other, less common problems, such as chronic prostatic infection, prostate cancer, bladder stones, and the like.

I really want to see Chen Mo afraid to write Light Novel

ALMIGHTY VIDEO GAME DESIGNER – Chapter 367: I really want to see Chen Mo afraid to write – Almighty Video Game Designer

Edited by Readers!

Chapter 367: I really want to see Chen Mo afraid to write


Before Lin Xue could scream, the perverted doctor had already punched the protagonist and knocked him down.

“Damn! He lied to me!! Wow, help!!”

Lin Xue really broke down, what the hell, why did I work so hard to get there? These mental patients got out of their hands, and as a result, they faced a more terrible mental illness!

And judging by the appearance, actions and facial features of this guy, this is a small BOSS, just like a fat man!

Although Xue Lin quickly realized that it was a plot murder, the unexpected twist still made her repeat the MMP in her heart!

The abnormal doctor threw the protagonist into the wheelchair, then tied the protagonist’s hands and pushed the wheelchair forward.

At this time, Lin Xue felt that the protagonist was completely out of control, and could only be pushed by a deranged doctor slowly walking down a narrow and dark corridor. This involuntary feeling was extremely overwhelming, causing Lin Xue’s fingertips to become numb involuntarily.

Looking left and right, Lin Xue said with a trembling voice, “Where are you going? I have a very ominous feeling. “0007

went to the door, said the crazy doctor. in a rather playful voice: “I love the air in the mountains at night, do you want to go out for a walk? Come on, I’m waiting for you here. Come on, run free! Oh don’t you wanna go? Good, then.”

The abnormal doctor kept pushing the main character.

Lin Xue was so angry, why the hell is this monster still here to entertain the protagonist? It must be evil Chen Mo Fun!

Kill Chen Mo, Turtle’s grandson!

Just make such a terrible game and even use monsters to entertain the players! It’s shameless!

“HEREWEARE.” (We’re here.)

“Thank you for coming, we’ll start right now, I should wash my hands first.” After that, the light was turned on. Lin Xue saw that the shell in front of her was full of blood, her ominous premonition intensified again.

The abnormal doctor spoke of “conceptual differences” between him and the priest. On the dirty instrument table next to him are various sharp instruments covered in blood.

No chapter, etc. – write in the comments.
Read without ads for free?!

Boning knives, long kitchen knives, large scissors

The perverted doctor talks to himself while fiddling… Holding these knives, he pointed to the main character’s right hand.

Lin Xue couldn’t help but get angry, “What the hell is this pervert?”

“Money has become a matter of faith. That is why I came here. I want let’s! Guys! Believe!

After muttering illogically to himself, the deranged doctor suddenly took a pair of large scissors over half a meter long and cut into the protagonist’s right hand. from!


Lin Xue almost screamed at the same time as the main character!

In the panic of the BGM, Lin Xue’s entire field of vision became blurred and covered in blood. The protagonist began to fight furiously, not daring to look at his right hand. But it heightened the feeling of horror in this scene!

Lin Xue clearly felt constant pain in her right index finger. Although this pain was not severe, it was enough to make Lin Xue’s heart rate increase and his blood pressure rise!

But that’s not all, the crazy doctor picked up the big scissors again and cut off the ring finger of the protagonist’s left hand!

Lin Xue clearly saw the main character’s two hands. At this time, his hands were stained with blood. Both the ring finger of his left hand and the index finger of his right hand were cut off, and his vision changed. blurred due to severe pain.

Lin Xue felt that those two fingers were in constant pain. This pain was not severe, but it was enough to block any other sensations in two fingers.

In other words, Lin Xue really feels like she’s had two of her fingers cut off!

The game is still going on, but Xue Lin is not in the mood to play anymore.

“Ah!!! Enough playing! I don’t want to play anymore!!!”

Lin Xue didn’t go to see what her friends were saying during the barrage, so she left the game right away, got out of the game booth.

She touched with two fingers with an old fear. Well, luckily they weren’t cut off.

What the hell is a game! Why is there such a section of the finger notch? I really want to scare people to death!!

Lin Xue felt like she was in a trance after playing for so long. Looks like she didn’t sleep well today!

Lin Xue feels her heart rate increase and her blood pressure rises, just like the protagonist in the game, who has involuntary shortness of breath.

When the broadcast was in a hurry, Ling Xue turned on the TV to find the sketch and turned it up to the highest volume. Ten minutes later, she still felt some tightening.

Terrified, Lin Xue had only one thought in her heart.

The horror game created by Chen Mo really can’t be played!!

Soon various test videos and live broadcasts of “Escape” began to appear on the Internet, and comments about this game began to grow.

“Fuck, what the hell did I do, why would I play this game, why!!!”

“This is awful, I lost ten minutes after entering. It’s not enough to scare people!”

“Mom, I’m going to a place like this to escape. Would I rather commit suicide?”

“That’s it, don’t play, it’s easy. Heart disease, chest tightness, palpitations and many other diseases. If you have the above symptoms, don’t forget to retire and protect your safety!”

“Isn’t the main character of the Japanese uncle a modern person? Why don’t you bring a mobile phone if you have a DV? Why! Shouldn’t you strongly call the police now?”

“Did you notice that ‘Escape’ is the same as ‘Digging for the Earth’, which is the quick screen of major live streaming platforms and video sites. Obviously, Chen Mo did it on purpose, and he deliberately retaliated against society!”

“Yes, why do you want to make horror games if you can’t make a good role-playing game? Chen Mo is definitely malicious!”

“I have only one idea now – kill Chen Mo, the turtle’s grandson! I was afraid to pee when I watched the video. How terrible it would be if I played it myself!”

“I want to know what will happen to Chen Mo playing this game alone? Damn, I left a message on his Weibo for him to play “Dig for Improvement” last time, but he cheated on him. This time I definitely want him to play himself!”

“That makes sense, the host is tired of watching the frightening pee collection, I want to watch Chen Mo’s frightening pee collection!”

“Yes, that makes sense, how can this let Chen Mo go? Gotta make him feel the same as other MCs who are afraid to write!”

“What if he ignores this time?”

“Leave a message on Weibo!”

“Do you think he will take care of Chen Mo’s shameless character?”

“Are there any tyrants here? The local tyrants are offering him a reward for playing!”

“Are you really kidding? Does Chen Mo run out of money? He throws you a double backhand!”

“Wow, what should I do, I can’t watch the live broadcast of Chen Mo’s Escape”, I feel like my life is all meaningless!”

“Soon, any major player can think of a way to excite Chen Mo and let him play Escape!”

“It’s impossible, Chen Mo is so steadfast. As an old dog, I don’t worry at all.”

“Anyway, let’s leave a message on Chen Mo’s Weibo!”

Soon, the players rushed to Chen Mo. Leave a message on Weibo urging him to play “Escape” live for everyone.

On December 31, 2022, the German post office closes the service for receiving and delivering telegrams due to its low demand. Undoubtedly, other countries will soon do the same for Germany.

Communication technology with an interesting history is finally disappearing from the scene.

This event deserves great and serious reflection and consideration. But I personally remember the telegraph most of all for one episode. More than half a century ago, I sent a telegram to the General Secretary of the Central Committee of the CPSU, Leonid Ilyich Brezhnev.
Why, why, what is KPC and much more you will learn from this story. It happened in the spring, but it fully claims to be a New Year’s, “tube” story for reading on a weekend or holiday. I hope it will be not only interesting for you, but also, perhaps, it will cheer you up a little.

I listened to a 2-hour speech “Healthy Sleep” by neurologist, somnologist Elena Tsareva the other day. She pulled out the most important points for herself:

  1. Sleeping regularly, going to bed and getting up at the same time is the most important thing.
  2. Biorhythms – partly inherited, partly regulated by lifestyle. You can influence them yourself.
  3. Normal bedtime is around 10:00 pm. Owl and lark – this is a deviation of ± 1-2 hours. More is a violation and a shift in the phase of sleep, more often due to external stimuli.
  4. The most common cause of poor sleep and difficulty falling asleep is the wrong light.
  5. To shift the regime by 1 hour, the body needs 1 day to adapt.
  6. It is impossible to “sleep through” a sleepless night. Getting enough sleep eliminates only 30% of the effects of lack of sleep.
  7. Before looking for the causes of poor sleep, rule out psychological problems (anxiety, depression), thyroid disorders, iron deficiency, diabetes, cardiovascular disease, and pathology of the kidneys and genitourinary system.
  8. Drivers and passengers: 17 hours without sleep equals 0.5 ppm, 21 hours without sleep equals 0.8 ppm.
  9. Do not stay in bed without sleep for more than 15 minutes – advice for insomnia.
  10. The most physiological alarm clocks are those that glow.

Under the cut is a summary of a 2-hour speech about sleep for 15 minutes of reading. Another point in the treasury of useful materials about sleep is Sleep Hackers.

My initial data: slight myopia, -1 diopter, but only 20% sharpness – I saw only two lines. Glasses or lenses were uncomfortable for me, so I decided to have an operation. The choice came down to just two types – Femto lasik or Smile.

Femto is a proven and reliable method, and I learned about Smile from the Habré articles from the Shilova clinic. However, when I started digging further, I realized that the Smile method has one serious drawback – the human factor.

2 years ago I had a femto lasik operation and I am still satisfied with it – immediately after the operation my vision was 120% sharp, and now it is around 100%. My friends and acquaintances are interested and ask if they should do Smile. I’m a little tired of explaining the same thing to everyone, so I decided to write an article on Habré, in which I collected all the information I could find.

The story of how I received my sight

For 10 years I wore lenses with myopia of -4 diopters and thought about the correction, but at one moment it clicked, I did it, I was happy like an elephant. With my myopia, it costs up to 100 tr.

Turnkey SuperFemtoLASIK (May 2019). But pants full of happiness.

I will immediately disclaim responsibility: I do not have a medical education, rich experience in operations and commercial motivation for writing this article. I describe this experience for people who are still in doubt and are looking for answers to their troubles on the Internet.
I will also use common abbreviations. Information about the essence of the methods is full on other resources. He also did not name the medicines, so that no one would guess to prescribe them to himself.


They put glasses on me in elementary school (-2 diopters), by the ninth grade I had already switched to two-week lenses (-3.5 diopters). At the end of the institute, relatives / friends began to incite for a correction, but then it seemed to me to spend the cost of 3-4 smartphones, or a good trip to Europe is too much. So I went and licked my lips until changes began: a close relative became seriously ill and oncology treatment cost a lot of money. Two years later, everything ended well, but another fell ill and everything started anew. At that moment, it clicked in my brain that health is not something that needs to be saved on. My 30s are over and it’s time to take care of my own health. At the same time, wearing contact lenses began to strain. Once a quarter, an emergency happened: when I accidentally scratched my eyelid, the lens ran over the eyeball and it was wildly difficult to get it, not to mention the sensations at that moment. One time it was driving, another time away from home and it was hard to come back. The feeling of helplessness was overwhelming.

Nanotechnology Electronics for beginners

From the sandbox

Several years ago I had a chance to try my hand at luring inquisitive youths into the development of microelectronics. And then it was, as in the well-known proverb: “The claw is stuck – the abyss is for the bird!” Could no longer stop. I want to share this experience with the public, perhaps other electronic engineers will also want to arrange something similar. Smarter people – better life.

It all started with the fact that we almost accidentally agreed with the Interregional Computer School in Dubna near Moscow to hold for their students something like a lecture on the design of microprocessors. This topic is known to me firsthand, I have been cooking in it for two decades. I had a chance to work both in domestic and foreign companies. Well, why not tell teenagers what the work of engineers is, inventing the insides of “prots”. This is not among the same bores at the conference to speak – in front of the children it will not work just to rattle the text. If they are not at all interested, then they do not care about honorable gray hairs, brilliant bald heads and pouting cheeks. They will yawn without hesitation and fidget in their chairs in the hope of escaping as soon as possible. But there are pluses – all sorts of liberties, jokes, inaccuracies and simplifications will not cause indignation and demands to burn the heretic speaker. In general, judging by the number of questions in the process of communication, the first pancake did not come out lumpy, it became interesting to move on.

Project management *Crowdsourcing DIY or DIY


Three years ago I decided to make a book about the high-rise of Moscow State University on the Lenin Hills – a large, illustrated, with the involvement of graduates, etc. The story of this work is a real movie (sometimes farce, sometimes horror) with a lot of dramatic twists. Super-successful crowdfunding, a wide audience, a lot of enthusiasts, a complete failure with planning, collecting all possible rakes and, as a result, an absolute fuckup in terms of budget and timing. In general, the classic story of “project management” – that’s why I decided to tell it here.

TL;DR – if you want to write non-fiction for the sake of money, forget it right away. But if the soul asks for adventure, life seems too simple – go for it! You will acquire a lot of unnecessary connections and discover a lot of shortcomings in yourself. But it will be fun 🙂

Yes, and this is a longread; Estimated reading time is 20 minutes.

PostgreSQL *

From the sandbox

Hello, Khabrovites! I bring to your attention the translation of the article “How a single PostgreSQL config change improved slow query performance by 50x” by Pavan Patibandla. It helped me a lot to improve the performance of PostgreSQL.

At Amplitude, our goal is to provide easy-to-use interactive product analytics so that everyone can find answers to their product questions. To ensure a good user experience, Amplitude must provide these answers quickly. So when one of our customers complained about how long it took to load the dropdown list of event properties in the Amplitude UI, we set out to investigate the issue in detail.

By monitoring latency at different levels, we realized that one particular PostgreSQL query took 20 seconds to complete. This came as a surprise to us, since both tables have indexes on the column being joined. Slow query

Game development *Game design *Game promotion *Games and game consoles

Last night, March 19, Google held its own presentation within the Game Developers Conference. The essence of what is happening is a new video streaming service that allows you to play from any device without the need for a powerful computer or console, and a special gamepad for it.

If that’s not enough, Google is introducing a new game studio run by Jade Raymond, former Ubisoft Montreal executive producer and Ubisoft Toronto managing director.

A quick overview of the presentation with screenshots – under the cut. Detailed text transcript, perhaps a little later.

Please note that under the cut there will be a lot of images in 1920×1080 resolution, which create good such traffic. Olso, I warned you.

Data Mining *Brainfuck *Big Data *Data visualization *Research and forecasting in IT *

From the sandbox

Who are we and what were the prerequisites for the project?

Good afternoon, my name is Lazarev Vladimir, I am the head of the BI integrator Analytics Group. We make visual reports for business on marketing, sales, finance, logistics based on the leading analytical platforms Qlik Sense, Power BI, Tableau.

The visual component is very important in BI platforms. If you have looked at dozens of demo reports of BI systems and you do not like how this or that platform looks, then most likely you will not implement it, even if you are satisfied with the price and technical characteristics. Based on this, the need is born to see the same data in different analytical platforms so that it can be compared.

And it is desirable that the data be interesting… 🙂

Where did the idea to make this report come from?

A few years ago, the Higher School of Economics published an article on the formation of prices for the services of girls with low social responsibility in Moscow. These were aggregated data from an analysis of 1,800 questionnaires. We found the data behind these conclusions of the HSE sociologists interesting. And we decided to work on this topic.

Mobile Application Development *Android Development *Google API *Reverse Engineering *Interview

Google loves Easter eggs. He loves it so much that you can find them in almost every product of the company. The tradition of Easter eggs in Android has been going on since the very first versions of the operating system (I think everyone knows what will happen if you click on the line with the Android version several times in the settings).

But it also happens that Easter eggs are found in the most unexpected places. There is even such a legend: once a programmer googled “mutex lock”, and instead of search results he got to the foo.bar page, solved all the problems and got a job at Google.

Event reconstruction

Here is the same amazing story (only without a happy ending) happened to me. Hidden messages where they definitely cannot be, reverse Java code and native libraries, a secret virtual machine, passing an interview at Google – all this is under the cut.

Math *Science

One urban legend has it that the maker of sugar sticks hanged himself after learning that consumers didn’t break them in half over a cup, but gently ripped the tip off. This, of course, is not so, but if one follows this logic, then one British lover of Guinness beer named William Gosset should not only hang himself, but also drill the Earth to the very center with his rotation in the coffin.
