On the Importance of Good User Interface Design

Written by V. Berba Velasco Jr.

It seems obvious, but itís often ignored. A good user interface design can spellrepparttar difference between acceptance of a software product and its failure inrepparttar 133438 marketplace. Ifrepparttar 133439 end-users findrepparttar 133440 software to be too cumbersome or difficult to understand, then an otherwise excellent product could be doomed to failure. The developerís goal should be to makerepparttar 133441 software as professional-looking and easy to use as possible.

Sadly, Iíve found that a great many companiesóespecially small or highly specialized software firmsópay little attention torepparttar 133442 mechanics of good user interface style. ďAs long as it works, thatís what matters!Ē seems to be their mantra, with little regard forrepparttar 133443 inconvenience that this imposes onrepparttar 133444 user.

Thankfully, thatís not how we operate at our company. Our team of developers invests considerable effort into making out user interfaces as intuitive and foolproof as possible, since we know that this is something our customers would appreciate. Iíve often commended my teammates for recognizing that excellence is worth pursuing.

Going back torepparttar 133445 topicÖ I canít remember how many times Iíve encountered software that was designed to work, but with little regard for ease of use. Ifrepparttar 133446 software forcesrepparttar 133447 operator to constantly consult a manual or a cheat sheet, then thatís a pretty good indication thatrepparttar 133448 user interface needs improvement. Similarly,repparttar 133449 software should allowrepparttar 133450 user to perform tasks quickly and efficiently, without sacrificing power and flexibility. This seems intuitive, and yet these considerations are so often lacking.

Splitting the Heat and the Noise

Written by Thomas Yoon

The most common air conditioning units we see nowadays isrepparttar air-cooled split unit. It used to berepparttar 133437 window unit many years ago. I guess it must be quietness ofrepparttar 133438 split units that wonrepparttar 133439 hearts ofrepparttar 133440 users.

In any air conditioning unit, there must be a process for absorbing heat fromrepparttar 133441 indoors and discharging it torepparttar 133442 outdoors. For air-cooled units,repparttar 133443 heat is discharged directly torepparttar 133444 atmosphere.

What'srepparttar 133445 difference then between window units and split units?

Inrepparttar 133446 window units,repparttar 133447 whole refrigeration circuit is installed in a box-like enclosure. The cold portion is separated fromrepparttar 133448 hot portion by partitions. Asrepparttar 133449 name suggests, usually it is installed at a window, mainly because this isrepparttar 133450 easiest place to make an opening inrepparttar 133451 wall. Failure to find a window opening may mean hackingrepparttar 133452 wall to create an opening roughlyrepparttar 133453 same size asrepparttar 133454 window air cond unit.

Becauserepparttar 133455 compressor, blower fan, condenser fans and other moving machinery are all installed inrepparttar 133456 same box, much ofrepparttar 133457 noise they make gets transmitted torepparttar 133458 room indoors. This type of air conditioning unit tends to be quite noisy.
