Caffeine keeps a computer from locking up or falling asleep by regularly simulating keystrokes. Like a strong cup of coffee, the program prevents your screensaver from kicking in without your having to disable the screensaver itself. It's handy for times when you don't want a screensaver but also don't want to change your desktop settings.
We enjoyed this program's interface, because it didn't try to overextend itself. Caffeine basically has only an on/off switch. It's pretty much impossible to be confused with such a simple layout. The program's description claims it simulated a keystroke once a minute in order to keep our computer from going to sleep. We had no way to prove or disprove whether the keystroke happened, but the program lived up to its billing: we left the computer idle for several minutes, which normally would have resulted in the screensaver kicking in, and nothing happened. Since that was what was supposed to happen (or not happen) it is obviously an effective way to keep your screen open. Caffeine is so simple and basic that it offers no features, special or otherwise. While this doesn't hurt its overall excellence, a timer or scheduler might be a smart inclusion. Regardless, this was a great way to keep a computer from lapsing into sleep.
Caffeine is a free program and browser extension designed to keep your computer awake, no matter what. The app is easy to use, lightweight, and can help if you have problems with your PC locking or going to sleep.
The Caffeine browser extension might be more useful if you're using a system where you cannot download and launch executables. Unfortunately, it's only available for Google Chrome, but the browser extension can help keep your computer awake as long as Google Chrome is open.
Caffeine requires no installation, and can even be used on systems with restricted access to .exe files. It does exactly what it sets out to do, and can be relied upon if a sleepy computer is getting in the way of your productivity.
The icon is shown above - it's the leftmost one in the task tray, and this is all you see. Double-clicking the icon empties the coffee pot (that's what the icon is) and temporarily disables the program. Double-clicking it again refills the pot, and will keep your machine awake. By default the app starts enabled, and works every 59 seconds. There are some command line switches you can use to alter this behaviour:
Two days ago I spilled coffee (2-3 tablespoons worth) on my Macbook Pro on accident. The coffee contained cream but no sugar. The first thing I did was grab some tissues and soak up the excess coffee, power down my computer (it did not immediately short out), and let it sit upside down.
I have read about using rubbing alcohol (90%+) to clean up coffee redisue. Can I pour that in the keyboard if my battery is still physically connected to the computer (but unseated from the logic board)? Or do I need to completely remove the battery from the enclosure before I try the rubbing alcohol trick?
I had same problem last wk, daughter knocked coffee (no sugar) on dell 1545 laptop, i panicked didnt unplug it straight away, screen went off. unplugged it, tipped upside down to drain, took battery /hdd out, mopped up and left a week. removed k/brd wiped inside. put back together, connected battery & lead, did start up but wouldnt recognise hdd. tried another from my daughters laptop and worked but most keys wouldnt, bought new k/brd 7, hdd 39.99 both fitted today, installed windows, back up and running. cant believe it, I do backup to an external hdd as my business accounts are on there. bought sata docking station 15 and the damaged hdd has shown up the files so will keep it just in case. hope this is of help to someone, dont bin it, cost me 62 which is cheaper than a new laptop. Best of luck
I have a problem with my Apple MAC pro. I spilled some rum on my keyboard and the computer stopped operating. I tried for several days to start the computer but didn't work. 15 days later I started the computer and it did start but it took me to step one, if I want to use English as the language, and second step was to reset my password or use the same one but I could not type as the key board does not repond and now I am stuck here, what should I do
I would definitely remove the battery after all and every other energy source that is connected to the computer or even within reach before starting cleaning. Every energy source attached or in range is a possible source for unwanted short cuts while using alcohol for cleaning purposes.
In your case I would even remove the logic board and would carefully and diligently clean it separately with alcohol. Maybe there is some coffee still somewhere on/under the motherboard. Then I would let it dry for a day before I would built it in and see what the status now is.
I am just adding to this thread to explain what I did to save my laptop. 3 hours ago i split half a litre of boiling hot black coffee on my desk which inevitably drowned my laptop which shut itself down within 5 seconds of it happening. I panicked and grabbed a towel to dry off the external fluid and it wouldnt turn on. I did a quick google which explaind to remove the battery and anything else you can (I have no idea how to do this, nor do I own a screwdriver to get the back off my PC) so i opened my laptop and flipped upside down and put it on a towel on the floor, i then put my hair dryer on the lowest heat blowing into the arch of the laptop whilst having a fan pointed directly at the device. I left it for about 10 minutes and was impatient, tried to turn on and it would turn on for 1 second then power off. I then left it for 2 hours from the original spill time and i am now writing this answer on it. It seems to be working OK for now. I just wanted to share advice for people who arent very technical. I have put the steps at the top for a quick read.
The Trojan Room coffee pot was a coffee machine located in the Computer Laboratory of the University of Cambridge, England. Created in 1991 by Quentin Stafford-Fraser and Paul Jardetzky, it was migrated from their laboratory network to the web in 1993 becoming the world's first webcam.
To save people working in the building the disappointment of finding the coffee machine empty after making the trip to the room, a camera was set up providing a live picture of the coffee pot to all desktop computers on the office network. After the camera was connected to the Internet a few years later, the coffee pot gained international renown as a feature of the fledgling World Wide Web, until it was retired in 2001.
The 128128 px greyscale camera was connected to the laboratory's local network through a video capture card fitted on an Acorn Archimedes computer. Researcher Quentin Stafford-Fraser wrote the client software, dubbed XCoffee and employing the X Window System protocol, while his colleague Paul Jardetzky wrote the server program.
In 1993, web browsers gained the ability to display images, and it soon became clear that this would be an easier way to make the picture available to users. The camera was connected to the Internet and the live picture became available via HTTP in November of the same year, by computer scientists Daniel Gordon and Martyn Johnson. It therefore became visible worldwide and grew into a popular landmark of the early web.
The last of the four or five coffee machines seen online, a Krups, was auctioned on eBay for 3,350 to the German news website Spiegel Online. The pot was later refurbished pro bono by Krups employees, and was switched on again in the magazine's editorial office. Since the summer of 2016, the coffee maker is on permanent loan to the Heinz Nixdorf MuseumsForum in Paderborn.
Spoofs of the Trojan Room coffee machine ranged from the Hyper Text Coffee Pot Control Protocol, a 1998 April Fools' Day specification for a communication protocol, to the 2002 video game Hitman 2: Silent Assassin, in which the player can destroy a "coffee camera" in a kitchen as a distraction. The coffee pot was also mentioned in the BBC Radio 4 drama The Archers on 24 February 2005.
Computers are a necessary ingredient for any successful business, including a coffee shop. They are used to manage inventory, handle your accounting and advertising and managing work schedules. Additionally, the coffee shop atmosphere is an ideal Internet cafe environment, allowing you to increase your customer base through the use of Wi-Fi.
Using a computer to track inventory and order shipments will simplify managing your coffee shop. There are literally dozens of software packages available that track and order inventory, including packages that can order supplies automatically if the inventory drops too low. Inventory software can benefit you by giving you in-depth reporting of how your inventory is moving and what is not. This will give you insight into your product popularity and allow you to plan future purchases around the items which earn more money. 041b061a72
