Charge job application fees to stop spamming

In the current fierce competition for limited job openings, some job applicants resort to resume spamming in the hope of getting one or two interviews out of hundreds of resume submissions. Companies have to use software or AI to eliminate the majority of such applications. This situation is bad for both job applicants and the companies. I have an idea on how to reduce the number of job applications without reducing the chance of hiring a good applicant. A company posting a job position should charge a small fee for each application, just like a college does. To prevent the company from abusing this practice e.g. trying to collect money instead of sincerely wanting to hire someone, they can donate the collected application fees to reputable charities and publish the numbers (how much was collected and donated, to what charities). Alternatively, they can ask the job applicants to, optionally, prove the applicants' donation to such charities in lieu of application fees.

If a college can collect application fees, why can't a company? Because a college is most likely non-profit, rarely for-profit, at least legally speaking. If that's the only real difference, donation of the job application fees by the company to charities solves this problem, and at the same time solves the big problem we're targeting, namely too many job applications, many of which are probably not a good match to the job description. Charging application fees forces the applicants to think twice and only send in their resumes when they think the job description matches their skills well.

If a job applicant genuinely has financial difficulties, the company should waive the fees on the condition that the applicant provides his/her latest tax returns.

With these measures, we achieve the goal of being able to meaningfully sift through submitted resumes and discouraging resume spamming.

Push button not responsive

Push buttons are widely used on all kinds of electronics. After many years of use, they may become less and less responsive when you push them. Here's an example of how to fix the button on a wall-mounted AC/heater thermostat. If most buttons are not very responsive, it's better to replace the whole thermostat. Otherwise, read on. The most used buttons may be the ones for temperature UP and DOWN. So it's possible only these two are not very responsive, i.e. when you press and hold the UP or DOWN button, it takes quite some time or even never to respond to your press. To fix this, remove the batteries. Pull on the face board straight out to remove the thermostat from the wall. Unscrew all the small screws. Lift off the circuit board. Use high concentration alcohol and a cotton swab to clean the circuit on the circuit board where the UP and DOWN push buttons touch. (You may clean the other parts of the circuit as well.) Now the critical part. The rubber buttons for UP and DOWN at the bottom side of the face board may have lost the carbon coating on the bottom side that touches the circuit. Unless you can find such buttons with good coating somewhere else, you can fix this by gluing a tiny piece of aluminum foil to the bottoms of the buttons. Make sure the foil is smaller than the button and does not stretch out of the edge. Press the circuit board onto the face board, and put the batteries back. Try pressing the UP or DOWN button. They should respond to your press immediately. Put back everything and you're done.

I wish there was an easy way to re-coat the carbon coating. I tried a regular HB pencil. It made no difference. Maybe a B-type pencil would be better. But even if it is, pencil carbon may not stick to the surface for long.

How to find the single mosquito indoors

New tools such as mosquito laser or bug zapper are impressive and efficient in killing mosquitos. But often times the big problem is not killing mosquitos per se, but finding them instead. It's likely you have one or a few mosquitos inside your house. Without finding them, a laser beam is useless and while a bug zapper may be attractive to a fly, it's not so to a mosquito. One way to find the mosquito or mosquitos that secretly sting you is to this. Turn off lights or keep the room somewhat dark. Put a mattress or anything you can comfortably lie on on the floor. Set up a mosquito tent on the mattress. Open the doors of the tent. Lie down on the mattress. Cover yourself with a light sheet and only expose your head. If you want to read on your cell phone or tablet, don't expose too much of your arm. Wait. Eventually the mosquito will come near your head. Once you hear the humming sound, immediately close the tent doors. Turn on the lights. Find the mosquito inside the tent and kill it. Note that to make sure the humming sound comes from the mosquito inside the tent, leave some space between your head and the edge of the tent.

While we're on the topic of mosquitos, here's a trick to kill a mosquito that perches on an edge or a crack of something where clapping your hands may not be able to kill it. When you buy fruits or vegetables at a grocery store, you use a small, usually no-color plastic bag. Use this bag to catch the mosquito (or even a fly, which is very hard to catch cleanly alive otherwise). Hold the opening of the bag wide open. Slowly move the opening toward the mosquito. When very close, suddenly cover the mosquito and its surrounding (edge of furniture, for instance) together, and close the opening. The mosquito (or fly) will be frantically fly around inside the bag.

Easy way to relieve workload on IRS

IRS is constantly under stress. “Our employees have worked hard, long hours during the pandemic to assist taxpayers and successfully modify our systems, despite lacking the funding that we need to adequately serve the American people,” said the IRS Commissioner. But there is a very easy to relieve this heavy workload: significantly raise the limit of tax filing. For example, currently if you are single, under 65, and make $12550 or more a year, you need to file tax returns. Why not raise that to, say, $20000 or $30000? To make up for the decrease in tax revenue of the nation, all or most tax rates can be raised just a little. The total tax revenue will stay the same but the number of tax returns that IRS receives will be much lower. Hasn't IRS been trying to simplify tax returns in the past few years (in spite of the alledge opposite on Turbo Tax's instigation)? Raising the minimum tax filing income works in the same spirit and will meet no or little opposition.

Better way to achieve slower traffic keep right

When I visited Italy, I was amazed at Italian drivers' courteous and considerate driving habit: before you pass a slower car, you're almost always guaranteed to have the left lane available for you to do so, even though before you come close to the point of passing, the slower car is in the left lane, or sometimes even running across both lanes. In the US, we have the Slower Traffic Keep Right sign everywhere on state or inter-state highways and yet far fewer drivers obey this rule than in Italy. One way to achieve the goal of slower traffic staying in the right lane is simple. Just make the pavement of the left lane rougher than the right lane. That way, driving in the left lane for an extended period of time is far noisier and less comfortable. In fact, when the road needs repairs, the government could even care less about the left lane, leaving small potholes alone for a longer time than those in the right lane. But that probably would not be a feasible strategy.

Cell phone pinned to car dashboard

If you don't want to buy or temporarily don't have a cell phone mount or cradle to fasten to the dashboard of your car, you can use a rubber band to pin the cell phone to the dashboard. Spread it so that it catches on the tabs of the two center A/C vents (the tabs that allow you to direct the air flow). Then slide your cell phone under the rubber band. If the distance between the two vent tabs is too big for the rubber band, link multiple rubber bands together. Or if there are two radio knobs (e.g. one for volume the other for tuning), see if the rubber band can be spread to catch on these knobs.

Single-person response speed training for martial arts

Martial arts require quick action, both in attack and defense. While one can train his speed of attack alone, it is almost impossible to train for speed of defense by himself. Two (or more) people have to work together. In sports, agility drill improves the athlete's change of body position and direction of running. But its emphasis is on the change of the body, not on the speed of response, which precedes the body movement and is more critical in any type of martial arts (boxing, Kung-fu, Taekwondo, etc.).

Although two-people training is needed for this training, it is not always convenient to arrange for two people and it inevitably causes injury. Just for the purpose of improving response speed, one-person training has its advantage, except that there is lack of such equipment. A possible design is a machine with a flat front plate. Multiple holes are open on the front. From each hole, a rod made of rubber can quickly pop out. The trainee stands close to the machine and has to quickly respond to the protruding rod by either turning his body to avoid it, or catching it with his hand.
