Blog #3: Describe How Weather Works in Regards to Clouds, Thunder, Lightning Etc
First of all there are three stages of how a thunderstorm is develop. These three stages is called Cumulus stage, the Mature stage, and the Dissipating stage. The Cumulus Stages is when warm air rise from the earth surface. There are different ways that upward current or draft of warm air form. Air can be forced upward at weather fronts, a boundary separating two air with different densities. This is where warm and cool air collide. Another way is when air from the ground heats up from the energy from the sun. which heats the air. The air will then rise to the atmosphere. If this warm air is moist or humid then it will condense into a cumulus cloud. This cloud will constantly grow as long as the warm air from the surface continue to rise. The second stage is the Mature Stage. When the cumulus continues to grow. it will eventually becomes very large. The water inside it , will become large and heavy. Tiny water droplets will start to fall , as more water from the rising is added to the droplets. The droplets will become heavy as it is no longer able to hold them up. The cloud will then starts to look dark and grey as more water is added. Simultaneously the cool air will enter the cloud and flow downward. The cool air will pull the heavy water downward because cool is heavier than warm air. Now that the cloud have a cycle of air coming up and down which is called a thunderstorm cell, the cloud is now called a cumulonimbus cloud. Thunder and lightning will start to take place as well as heavy rain. The cycle of air within the clouds will gradual accumulate electric charge as it will past by other air. This growth of electric charge will create lightning to form. Third and Final stage is the Dissipating Stage. The cool air going downward will become stronger than the warm air coming upward which the storm will break and starts to weaken. Now that the warm air could no longer rise, water droplets will no longer form. The storm will eventually die out and cloud will disappear. This whole process takes an hour for a normal thunderstorm, however a much more powerful thunderstorm will take several hours. RELATED QUESTION Why is the speed of the centrifugal compressor is kept higher than that of centrifugal pump? Centrifugal gas compressors are limited by a stress limited tip speed. In general, smaller frame sizes have higher nominal speeds than larger units mainly due to the larger impeller stresses in larger wheels. Mathematically, stress is directly proportional to the square of tip speed. With less denser materials, you can drive to higher speeds. A typical example would be an automotive turbocharger compressing air, made of single aluminum stages where 60,000100,000 RPMs are not unheard of. The process gas compressor are limited to lower speeds due to a steel alloy makeup and practical constraints of rotor dynamics and thermomechanical stress in multi stage units.
Video Games in 2060: an Essay on Exploding Heads
Video Games in 2060: an Essay on Exploding Heads
There is a shadowy hall lined on either side with glass, a museum, with the bachelor suite-sized display cases you’d expect in such a place. Instead of stuffed neanderthals, each dusty case holds a plastic person playing a replica machine. Close to the exhibit entrance, a young couple of mannequins with their bell-bottoms on shag work Pong on an old Zenith set. Down the way there’s a fake kid on display with a mushroom cut. He’s fumbling with Super Mario World on the 12-inch GoldStar his parents finally let him keep in his bedroom. The Wii gets its own special room in the exhibit, sponsored by Toyota, who nowadays make holographic cats* and other household appliances. No one is here. The ticket-taker has fled to higher ground.It is 2060, and the video game is a strange, intangible thing that has ignited war.It all started with Project Natal: a crude Microsoft tech demo that first appeared in 2009. The masses met a virtual boy named Milo who seemed to communicate with the real-world player. Microsoft touted their controllerless concept as the future of gaming. Critics thought Natal was the next logical step in the motion control, made possible, even essential (for Microsoft’s survival), by the Wii’s unexpected popularity.But the technology was, in the end, too simplistic to provide developers of serious games with the tools to create anything beyond novelty titles that, nonetheless, excited everyone.In turn, the eighth generation of gaming saw a significant rift in the market, as video games truly went mainstream with the release of Microsoft’s controllerless new console, the committee-named YBox, and its slogan: “Think outside the Xbox.” The hardcore gamers were driven underground, in the same way that fans of decent music dug deep in the 90s. They ironically were drawn back to computers, where indie developers offering deeper, old school-style gameplay thrived.Meanwhile, parents bought YBoxes like their kids needed the devices to breathe. And if you heard the begging and prodding some kids subjected their parents to at launch, you’d understand why the parents were so easy to break. It didn’t help that the parents wanted a YBox too. They’d grown up either playing games or watching their friends play games, and this was the latest thing. Everyone else was doing it. So why not There were more exercise games. There were more racing games. The newly-amalgamated Sega-Ubisoft created a summer Olympics game with ten events, including the triple jump, that proved a big hit. Finally a fun Olympics title, the spiritual successor to WiiSports, it seemed.Nintendo, faced with pressure, decided to stay with the old workhorse Wii, which was already in so many North American homes. The company that was once synonymous with video games opted for new patches and introduced a new controller made up of five white rings — one for each finger and the thumb — connected by a wire. If the player bent a finger it was like pressing a button. This allowed for unparalleled control of in-game activity — especially in sports games and first-person shooters. Then there was Sony, the other big player. Their Playstation 3 ultimately emerged the victor in the seventh generation console wars, the underdog who pushed ahead half-way through the race. But when the YBox hit, the almighty Sony rushed out the PS4 and the camera-based with wand controls were seen as the most dated of the bunch. The “chocolate bar” just couldn’t compete with the Natal, or the Wii’s new Power Glove Plus 64.Eventually the big film studios, frustrated with so many bad movies based on game franchises when better games were basically interactive movies, began to make games themselves, casting major actors in playable character roles. Movies had become as stuffed with computer graphics as games anyway, why not let viewers control the action After many crazy ideas were shot down by timid execs, the result of consensus was button prompts. Each moviegoer was given a disposable controller with four coloured buttons, marked a) b) c) d), and at key plot points in these new movies, viewers were asked to choose what would happen next. It was a voting system. Democracy of a sort. The most popular answer won.** This led to many brawls in theatres. The people who wanted bad things to happen almost never got their way, and as we can well imagine, people who wish for bad things to happen aren’t always so friendly when they have to sit through so many happy endings.Eventually the lines between movies and games became so blurred, and the titles themselves so simplistic, that the popularity of games finally began to wane among young adults, in favour of soccer, which finally took off in North America after the rules were changed to allow robot players and the American robotic companies began to clean up in the Olympics and World Cup.*** This also led to brawls, which was less surprising because it’s soccer. It was then, when games had lost their mass appeal to consumer frustration and boredom, that the upstart Neurovision rose to prominence. It was the brainchild of three disparate developers. Fed up with their inability to tell the complex stories they had hoped increasingly powerful techonology would allow, Neurovision promised a new kind of video game, one played entirely in the player’s head. They called their console the Neurovision 49582AR7 — by the 2040’s, all the good names had been taken. Wags in the blogosphere, now the most respected, but dying forum of free thought, nicknamed the device “headgear” on account of its appearance, specifically because of the awkward requirement of early models to slip over the player’s incisors.Launch titles included Capcom-Sega-Ubisoft-Walmart’s Super Street Fighter 35 Turbo 49582AR7, and Call of Duty: War of 1812. Both games, incidentally, involved Canadians burning down the White House. Eventually developers began making games that made people think again. Games emerged that allowed players to feel every sensation of reality in a fictitious world, to be characters in past and future lands, fight wars, find love.By 2052, the technology had improved to the point where the players didn’t need any plastic wrapped around their heads at all. Games were nasal sprays. Players could be sitting on the space bus, fighting off zombies in their head, sure to hit pause every so often to check to see if their astro-stop was coming up. It was pretty cool, until rare cases of players developing severe migraines, and then schizophrenia, ignited fears that snorting nano-machines that worked their way into the player’s brain and attached themselves forever, were somehow unsafe. Tests were ordered by the International Ministry of Science and Health, and the result: Yeah. Probably shouldn’t be doing that.Soon it was discovered that the machines were actually flammable, and it was unsafe for players to be near holographic cats in the same way that it was unsafe to talk on cell phones at gas stations.Few people wanted to play a video game after their friend’s head exploded in a ball of fire. Such a wound required at least a couple weeks in the hospital. Games were eventually declared illegal, forcing the few remaining die-hard players underground. Thus began the War on Games, like the War on Drugs before it. Police would lock up people possessing spray bottles of Quintuple Dragon or Mario & Master Chief at the Uranus Games, while activists claimed it was the player’s right to risk having their head explode. In light of this, old school gaming was re-embraced by the UCAS government.**** Ancient consoles from the NES to the PS2 were refurbished and sent out to schools as a sort of anti-game propaganda. Of course, when it was discovered that these “head-explosion-free” systems contained all manner of devices to spy on the populace (everything from microphones, thermal imaging cameras and devices to steal fingerprints hidden in the buttons), it ignited a real war. The state vs. the players. The latter use generations of practicing war in games to their benefit.EpilogueThe New Civil War eventually culminates in the development of the THX-800, known informally as the “Technology Bomb.” During a Rebel tactical strike, all of the tech bombs in the world are mistakenly detonated, wiping out all electronic devices of any kind, and the Neurovision users too. Mankind is sent into a state of flux and anarchy for a hundred years. When some measure of civility returns to the world by 2160, mankind is effectively back in the Stone Age, and is given a fresh slate to start rebuilding the world they once had. Tic Tac Toe, Hopscotch and Horseshoes become the biggest names in gaming.However, even after having the remnants of our society washed away in a torrent of blood and broken circuits, legends persist. Crowded around campfires, humans tell their children grandiose tales of plumbers who saved princesses, young heroes who saved kingdoms, warring robotic soldiers, and lightning fast blue rodents. These stories become part of the fabric of life for the new human. Eventually, the stories are codified into religions. Most follow the teachings of the Mushroom Kingdom of Heaven or Xboxism, but there are also fringe cults and smaller religions like Master Systemology, Praystation, the CapKonamicons (who’s numbers are decimated when The Mega Men and the Solid Snakes separate to form their own religions) and the Colecovisionaries. Eventually, these differing beliefs would lead to more conflict, but that’s a story for another time.* Real cats died out in the 2040’s after the cat-flu outbreak, so the strain was rebranded “SFDS” in order to shelter the failing cat industry.** Tarantino especially loved this device. And George Lucas, on his deathbed, demanded a new set of Star Wars remakes utilizing the technology.*** Japan reverted to feudalism in 2034.**** The United Canadian and American States, which is Canada and most of the east coast of the US, while most of the west and mid-west of the US has been reclaimed by aboriginals. Shadowrun is awesome.
Linux Backup Utility for Incremental Backups
Linux Backup Utility for Incremental Backups
And why are you not considering git itself? The strategy you describe, after one full and two incremental backups, has it's complications when you continue. It is easy to make mistakes, and it can get very inefficient, depending on the changes. There would have to be a kind of rotation, ie from time to time you make a new full backup - and then do you want to keep the old one or not?Given a working dir "testdir" containing some project (files, and subdirs), git makes by default a hidden . git subdir for the data. That would be for the local, additional version control features. For backup, you can archive/copy it away to a medium or clone it via network. The revision control you get (without asking for) is a side effect of git's differential storage. You can leave out all the forking/branching and so on. This means you have one branch called "master". Before you can commit (actually write to the git archive/repo), you have to configure a minimal user for the config file. Then you should first learn and test in a subdir (maybe tmpfs). Git is just as tricky as tar, sometimes.Anyway, as a comment says: backing up is easy, hard part is the restoring.Disadvantages of git would be just the small overhead/overkill. Advantages are: git tracks content and file names. It only saves what is necessary, based on a diff (for text files at least).I have 3 files in a dir. After git init, git add . and git commit I have a 260K .git dir.Then I cp -r .git /tmp/abpic.git (a good place to save a backup:). I rm the 154K jpg, and also change one text file. I also rm -r . git. Before restoring the files I can get the precise differences:Here I want to follow the git restore hint.After git --git-dir=/tmp/abpic.git/ restore *:The jpeg is back, and text file btext has not been updated (keeps timestamp). The modifications in atext are overwritten. To reunite the repo and the (working) dir you can just copy it back. The files in the current dir are identical to the .git archive (after the restore). New changes will be displayed and can be added and committed, without any planning. You only have to store it to another medium, for backup purposes. After a file is modified, you can use status or diff:And just like git knows about "more" in file 'btext', it will also only store that line incrementally. After git add . (or git add btext) the status command switches from red to green and the commit gives you the info. And you can really get at the contents, somehow:And then the first 4 hex hash digits To travel back in time by one commit it is:btext's blob has a different hash before the last commit, the others have the same.An overview would be: Instead of manually timestamped tar files you have commits with a message and date (and an author). Logically attached to these commits are the file lists and contents. Simple git is 20% more complicated than tar, but you get decisive 50% more functionality from it. I wanted to make OP's third change: change a file plus two new 'picture' files. I did, but now I have:So what did that Your Name Guy do exactly, in his two commits, shortly before 6 pm?The last commit's details are:And to check the second-to-last commit, whose message announces two pictures:This happened because I tried git commit -a to shortcut git add . , and the two files were new (untracked). It showed in red with git status, but as I say git is not less tricky than tar, or unix."Your debutante just knows what you need, but I know what you want" (or the other way round. Point is it's not always the same)1. How to fix Time Machine's "This backup is too large for the backup disk”?This happened to me recently; I was pretty annoyed because I expected that if there was not enough space, Time Machine should just delete the oldest backup.The problem turned out to be that the disk contained only one (large) backup, and did not have room to store the current delta (delta = changes to files since last backup).I realized this when I looked at the disk contents and saw that there was only one backup folder under Backups.backupdb. I used Disk Inventory X to look at the contents of my hard disk, and identified a few large folders which did not need to be backed up. I excluded these from the backup using "Time Machine" > "Options" > "Exclude these items from backups". The info from Disk Inventory X also led me to delete a bunch of large unused files.After the two changes listed above, the backup proceeded successfully. I did not have to launch the backup, it automatically retried. I presume that my changes brought the delta to a small enough size that it fit in the remaining free space on the backup disk.UPDATE: This happened to me again recently, and just excluding folders from the backup was not enough, so I found another trick. Let's say you analyze your hard disk contents and realize there's a 20GB folder (let's call it UselessStuff) which was being backed up. You exclude it from the backup as described above, but that does not delete the previous backups of UselessStuff from the disk, and you still do not have enough space for the backup to complete. Since you do not need any backups of UselessStuff, you can enter Time Machine, right click on UselessStuff, and click "Delete all backups...". In my case, this freed up enough space to let the backup continue successfully.2. Backup large files in an external diskAddonics manufactures a range of HDD duplicators that duplicates hard disks very fast without any connected computers. From naked disks, their solutions also support USB-to-USB copy, etc. Do check it out.We have one in the office, limited application, but it is the most frictionless way to duplicate large files (in fact, the whole disk) to another.3. MSSQL Backup QuestionThere are two ways people backup databases. One is to do dump of the database (i am not a dba so i am not sure the mechanics of doing the dump) to a text file, then write that file to tape. The second is to use an agent that is aware of the RDBMS that you are using. Both of these methods will get you everything you need to restore the DB to a working condition. You can use backup exec, but you will need to make sure that the MSSQL Agent is installed on those systems. Since you have more that 250 server's i am guessing you have at least one dba on staff - I would ask them as to how backups of the SQL servers are currently being done. They should know some of the basics at least enough to get you started. They would know things like whether your predecessor used an agent, or backed up text dumps
Is It Possible to Reverse Openings of an Already Installed Glass Sliding Door?
Is It Possible to Reverse Openings of an Already Installed Glass Sliding Door?
I do not think most doors can be changed without removing the door1. someone knocked on my sliding door?Something like this happened to me recently. Do not worry or panic. If you seriously feel like someone's trying to get in call 911. If not it might be a neighbor. Once my neighbor kept knocking on my door, turns out he was just looking for my dad to ask about his lawn or something. Another time a cop rang my door bell at 12:00 am and I did not open because he did not even say he was a cop he just kept knocking. So just use your gut and common sense2. Do your cats get jealous of each other if you donu2019t give them equal attention?Yes! I have three indoor cats and a stray that adopted us who is strictly outdoor. He is so jealous of the indoor cats that get to be with us when we are in the house that he will go from window to window to antagonize them and get our attention if I have not gone outside that morning!I also bought a purfect fence years ago for my indoor kids to get a taste of the outdoors. We set it up around my bedroom sliding door with their own cat door so they can come and go as they please whenever I open it. Well, we bought the fence before Storm adopted us, so we thought nothing of setting the pen up so one side runs along the pool fence. The perfect fence's top is connected to hinged arms so if the cats climb up the wire the arm falls under their weight and they cannot escape. It does nothing to keep cats out, however, when they hop on the pool fence (which is about half the height of the purfect fence) then jump on to the purfect fence, into the pen, and prance their way through the cat door into the house.3. Does this sliding door lock work well on sliding glass doors?In the 70's and 80's my best friend owned a lot of rental property. We did all the maintenance and dealt with all kinds of tenants. I have also rented on several occasions. There are good and bad folks on both sides of "that fence". Unfortunately I do not know the law in Texas. As a rule I would think that non-life threatening issues would have a 30 day time limit to respond. You did the right thing by putting your request in writing. After 30 days you may have the right to hire someone to do the work and deduct it from your rent. Be sure to include a copy of your original letter and receipt from the installer. But Wait. You say you have notified them Multiple times already. In less than a month no less! Ouch! If the second lock falls under the heading of "Minimum Housing Code Violation" then repeat request may have been in order. If not... As an interim measure the old "board in the track" trick does work well. Hope I have been of some help to you. Good luck4. Has your Snuggie ever got caught in a sliding door?Hi WTH Is A Snuggie cuz it sounds WEIRD Are you some like freaky head? What is a snuggie????5. How do you unfreeze a sliding door on a metal shed?Hot water will quickly freeze leaving more ice to deal with. Pour de-iceing alcohol , rubbing alcohol, or even automotive windshield washer anti freeze on the tracks. Wait a few min for it to work. Avoid salt since it will soon corode and rust away the doors and tracks. Next time you close the doors try laying a towel or even a protective board to shield the track from drifting snow which will turn to ice,,,good luck6. Is it safe to sleep in the basement by myself if there is a large glass sliding door?if someone wants to get in your house/car they will. its very random on where crime strikes. if noone has tried to get in your house by the basement before i would say your pretty safe. an easy cheap safety device is to take a broom handle n place it in the door runner - we used this 'security system' for years. good luck
What's the Best Type of Marble for Your Kitchen Floor?
What's the Best Type of Marble for Your Kitchen Floor?
Marble flooring is one of the more popular types of flooring tile that people use nowadays in their homes. Although the use of marble as flooring tile dates back to the time of the Greeks and Romans, it is now finding its way back to people's homes, and more specifically, to their kitchens.What is marble?Marble is actually the result of the exposure of limestone to high temperature and pressure, causing it to crystallize into the natural material that we now know as marble. It comes in a variety of colors, designs and patterns, as well as shapes and sizes, making it very ideal for use as tiles for flooring, countertop, and other similar applications. However, what makes marble tiles so appealing to be used as flooring tiles is its characteristic of being durable and aesthetically pleasing at the same time. It is a durable material, making it easy for it to resist stains very well. This is probably one of the main reasons why marble is considered to be one of the best materials for flooring.Marble as kitchen flooringAlthough marble can be used for flooring in the kitchen, not all of them offer the same type of quality and effectiveness as with some other types of marble, which is why there are only certain marble types that would be considered as the best ones to be used for such a purpose.Marble comes in a variety of grades, depending on how durable and resistant it is to breakage, with Grade A marble being the most durable and resistant. If you are going to use marble for your kitchen floor, you must make sure that the grade of the marble that you are getting is of the highest one, especially since you are going to use it in an area where there will be a lot of possible contact with the floor through different mediums, such as the appliances, kitchen utensils, food ingredients, as well as liquid substances. You need to make sure that the type of marble that you are using in the kitchen is durable and resistant enough to handle a few bumps, scrapes and slams, in order to avoid major damage to the marble flooring like cracks and breakage.It is also wise to use marble types that need the least amount of reinforcement, which means that it will be able to handle stains, as well as breakage, with very minimal support from sealants and protections. This is important if you want your marble flooring to last in the kitchen, especially since the kitchen is the place where a lot of mishaps and accidents occur, and in consistent durations.One such marble type that offers most of that is the "tumbled" marble. It not only is durable enough to handle breakage, but is also resistant enough that it can handle the possible stains and damage with minimal support, but this does not mean that you can just leave a spill on it. You still need to take care of the marble flooring regardless of its ability to resist stain.However, these are not the only characteristics that make tumbled marble so appropriate for kitchen flooring. This type of marble is considered as appropriate for an area such as the kitchen due to the fact that tumbled marble has a less slippery finish, thereby reducing the chances of accidents due to slips from happening. "Honed" marble is also less slippery, due to its dull, matter surface. However, this type of marble is more susceptible to stains and abrasions, making it a problem to have in the kitchen.Vanessa Arellano Doctor
