What is your favorite software bug/fault horror story?
This one happened to me. I was in my second year in college taking a multimedia class and the professor asked us to write an s of different shapes and sizes. We send it to the professor well in advance and forget about it. After a while our grade is released and to our surprise it's a freaking zero. There's a little remark from our professor saying our code did not produce correct results. What could've gone wrong? So we get down to debug. One hour goes by. Two. A whole day. Several days. We just can't figure it out. I test in myputer for every corner case I can think of and my partner does the same on herputer and it works every time. Even Valgrind says we're a-ok so it's not an issue with memory corruption. We ask our professor for his test we had with every operating system we could think of. And all it took us was a week to fix it According to the grading criteria we should get a one for turning in our project one week late. Of course I had a good long talk with the professor exed exactly what had gone wrong fixed that line before his eyes and showed him how great our code was with all the good practices and documentation. In the end he agreed to give us a 9 out of 1. I could live with that. But I'll never trustpilers to be consistent ever again. UPDATE Someone pointed out this was an issue with the standard library not thepiler. That's probably correct because otherwise that simple division or double casting would be giving inconsistent results in the same machine. But saying that the issue was the standard library implementation doesn't reflect the deeper concern which is that even functions defined in the language standard aren't well enough specified to avoid this kind of inconsistency. The same difficulty is a major cause for inconsistencies in the grammar implementations which do generatepiler-specific problems - as pointed out in other answers. So I'll keep that last sentence like this for the sake of being more general.

Why are air conditioners mounted in windows?
Not all air conditioners are made to be window-mounted although new designs are slower to overtake this traditional design in the USA. Window air conditioners were so designed in order to give them access to both the internal room atmosphere and the outside air through a ready-made opening in the wall. They operate by taking room air and chilling it then blowing it back into the room. The coolingpressor generates heat and the unit blows air across the heat exchanger (which looks like a car radiator's heat exchange fins) and then to the outside. When fresh outside air is desired the user may open a small vent from the outside so that a small volume of outside air can be added to the room air. Window air conditioners do not cool a steady stream of air from outside. Modern room air conditioners are split similar to the arrangement of whole-home central air conditioner units. Thepressor and heat exchanger unit and its fan (BTW the noisy parts) are mounted outside and a wall-mounted unit located inside uses the chilled coolant to cool room air. The coolant circulates between the hot and cold parts of the system in two one-way insulated tubes. The tubes pass through a small hole in the wall.n As the image shows a singlepressor can support more than one room unit. The room units are mounted high on the wall cooling the warmest air in the room and distributing cool air that will sink toward the floor. The room units have VERY quiet fans. Split units have no vents to bring in outside air but the room's windows are no longer blocked. A big advantage of these split systems is that there are no ducts to rob space from the rooms.

Does split AC take fresh air from atmosphere?
No Split ac consists of two separate units. The outdoor unit basically has thepressor which is mainponent in the heat exchange process. Image Source Google Image Search italic The indoor unit just recirculates air and blows it through the cold evaporator fins. This cools the air and the same air is recirculated. So there is some minor air thates in the rooms though small openings in doors and windows (as they are usually not 1 percent sealed). So the atmospheric air is used for the outdoor unit to blow that though the condenser. But as far as the room being cooled is concerned there is no fresh air being introduced in any Air Conditioner system split or windows!
Why should one choose split ac over window ac?
Window AC v Split AC Space Split ACs are divided into Two units but do not need special cut outs like window AC 1 Ease of Installation Windows AC are much easier to Install and uninstall. Thus if you stay on Rent Window AC may be preferable if you plan to move in a few months 1 Sound Split ACs are much quieter than Window AC 1 Looks Split ACs are installed above normal eye level. Windows ac have to be installed lower and also block light from window reducing natural illumination 1 Cooling Effectivity Split ACs blow more air and can cool more efficiently 1 Power efficiency and Pricing Generally Split ACs will be costlier by 132 percent than the windows AC with similar efficiency and capacity. Split AC prices are falling drastically and newer technology such as inverter is available only in Split ACs 1 But Split ACs are more efficient. As you can see in below s 254 647 Maintenance Split ACs need more careful and specialized maintenance than window ACs 1 Please refer to the below posts for more info on AC buying Vivek Ravindranath's answer to As a first time buyer how how do I go about purchasing a new AC? answer aid 22459758 Vivek Ravindranath's answer to How efficient are inverter air conditioners? answer aid 2299764 Also below is more detailed info on the discussed topic Source How to Decide Between Choosing Window or Split AC - Review Center India Which Air Conditioner to buy? Window or Split? Look inside your Home for Space Window and Split and two entire differently sized products and we need to take care of this at utmost importance that whether we can install a window AC at home or the split one. A split conditioner is divided into two separate units wherepressor and condenser is the part of an external unit (ODU 3 Outdoor Unit ) whereas the internal unit has the evaporative part which we may call as IDU ( Indoor Unit ). While on the other side a window conditioner has all (condenserpressor expansion valve and all otherponents built) into one cuboid shaped unit. Hence when we talk about space a Split AC shall require more space technically whenpared with window AC however practically both has its own importance. Which point we need to take here is of the outer unit or placement ofpressor unit outside home. People who lives in a flat usually has a hard time finding a big opening for window AC and then choosing a Split AC is the only option left to them. No matter whether you choose window or Split you must know that outer end of both s require proper air ventilation. If youll install outer unit in a not so ventilated space youll find your AC struggling to provide you effective cooling. In most cases for those who has space for window AC can install split AC easily. The biggest benefit of having split AC is you can install its outer unit to any distance you want for providing it with air ventilation. Whereas with window AC youre restricted to install at places like window or at that end of room where at back proper ventilation is available. Hence in many cases where people are inclined to buy window AC end up installing their air conditioners at wrong location in room where it may also ruin the look of the interior too. Even I had issues when I wanted to install my window AC with outer end towards staircase of building. And my neighbour was not so happy with my decision as they were worried about heat dissipating from it. Still i got it installed anyhow. And with split AC you can install it at any location of your room as per your convenience or as per your interior design. All you need to take care of connecting piping which can be easily hided behind the walls or by covering it any means which may not even ruin your interior design of room. Ease of Installation Split AC only require a 3u233 hole to connect IDU to ODU for passing through required piping and that hole is hidden behind IDU. Hence the whole work is done beautifully whereas in case of window AC it requires a bigger opening than the AC itself to fit whole AC into it for supporting purpose. And in case if you live in a house on rent you probably can convince your landlord for doing so. Whereas with split AC things get easy. The biggest advantage of having a Split AC is that you can install its IDU any far within limit mentioned bypany. However those limits are quiet good and there isn anything to be worry of. Do not afford to ruin your Baby Sleep or Even Yours! Window AC are not silent. They do make noise as it has all noisyponents fitted into one cuboid. So if youre like a person who need silence for sleeping or if youre worried for your baby sleep prefer to buy a Split AC. Split AC has all noisyponents installed in ODU which is far to disturb your Sleep in any way. And even the IDU of split AC are usually silent all thanks to the new technology andpetition. LG split air conditioners are probably the most silent one and youll probably not notice any sound during running position. Aesthetics These days looks matter a lot for people. Gone are the days where you might want to put any AC on wall which may ruin your interior. Ill never prefer to do so ever. Here also Split AC has an advantage that they looks way better than window AC and now a days even many interior designers take them as a part of design. However even looks of window AC are improving if you may check Window AC of Hitachi . Cooling efficiency Since Split ACpressor is installed outside in ODU all heatingponents are fitted outside your room and is installed at a properly ventilated place hence it put less load onpressor to work and hence less electricity consumption however It might differ from place to place. The point to be taken care here is that the connecting pipes of IDU and ODU must be properly insulated or cooling efficiency can drop. Don worry If youll buy AC from a good brand who has great after sales service (like LG) youll not face any installation issue. But do mind that technically for same tonnage window and Split has almost same electricity consumption rate. Electricity Consumption Although everyone says that electricity consumption for both window and Split are same. Technically that also . But as per my experience I have felt that when on auto mode Split AC cool down faster your room than window AC as their air throwingponent is spread out at longer span and air throwing speed is also higher. Window AC has only a small window for throwing air may be that why they are called as Window AC and same theory goes for Split AC too ). Also window AC can effectively cool down area only less than 3 Sq. Ft. With maximum tonnage available whereas in split AC there isn any limit. And basically the point I am trying to tell you here is faster your room gets cooledpressor cut shall happen earlier then whatpared to window AC. Also Split AC technology wise has got way much better than window AC as mostpanies inclines to sell those more hence more R&D work are done on them. Inverter series air conditioners which is the latest trend are available in split AC only. Sometimes I felt that buying a window AC shall make you feel that youre buying a product which anypany don wanna sell but they have to because market demands them. That the only reason why youll never see any TV advertisements on window AC. Capacity Requirements Since window AC is whole one unit it size is directly proportional to the tonnage capacity. Higher the capacity bigger the size. Because of such reason window AC are available only up to 2 tons capacity. Whereas in case of split AC the real work of cooling down air is done in external unit (ODU) and it can be of any size as it is installed outside. Hence there isn any tonnage limit on those. Please do mind reading this that if you have a bigger area needs to be cooled and while calculating your tonnage requirements Ites out to be 3 tons then don buy one unit of 3 tons rather buy 2 units of 1.5 tons or 1 two tons and 1 one ton AC. I am saying this because many a times you might not require to cool down whole area in those cases you can switch ON only one AC and save electricity consumption. Also if by chance one AC broke down youll still have one working so that your work flow may not get effected. Suitability Window AC are successful only when being installed in small rooms in apartments or offices. However formercial places and largeplex and even at home Split AC has proved to be more successful. Pricing Pricing point even when i listed here at last is one of the biggest deciding factors for most consumers. I feel that consumers must look for product quality first and keep the pricing at least priority. We want our air conditioners to work for years and hence doing one time investment even if the product is costlier is much better than saving money at initial period by buying low cost AC.
