An SSD write operation can be done to a single page but, due to hardware limitations, erase commands always affect entire blocks consequently, writing data to empty pages on an SSD is very fast, but slows down considerably once previously written pages need to be overwritten. If they happen to contain data, the contents must be erased before a write operation. NAND flash memory cells can be directly written to only when they are empty. Example: 512 kiB blocks that group 128 pages of 4 kiB each. SSDs store data in flash memory cells that are grouped into pages typically of 4 to 16 kiB, grouped together into blocks of typically 128 to 512 pages. For magnetic disks, an overwrite of existing data is no different from writing into an empty sector, but because of how some SSDs function at the lowest level, an overwrite produces significant overhead compared with writing data into an empty page, potentially crippling write performance. While this often enables undelete tools to recover files from electromechanical hard disks, despite the files being reported as "deleted" by the operating system, it also means that when the operating system later performs a write operation to one of the sectors, which it considers free space, it effectively becomes an overwrite operation from the point of view of the storage medium. Since a common SSD has no knowledge of the file system structures, including the list of unused blocks/sectors, the storage medium remains unaware that the blocks have become available. Contrary to (for example) an overwrite operation, a delete will not involve a physical write to the sectors that contain the data. Background īecause of the way that many file systems handle delete operations, by flagging data blocks as "not in use", storage media (SSDs, but also traditional hard drives) generally do not know which sectors/pages are truly in use and which can be considered free space. TRIM is also widely used on shingled magnetic recording (SMR) hard drives. Although this successfully maintained their lifetime and performance even under operating systems that did not support trim, it had the associated drawbacks of increased write amplification and wear of the flash cells. As of 2023, many SSDs had internal garbage collection mechanisms for certain filesystem(s) (such as FAT32, NTFS, APFS) that worked independently of trimming. Īlthough tools to "reset" some drives to a fresh state were already available before the introduction of trimming, they also delete all data on the drive, which makes them impractical to use for ongoing optimization. Trimming enables the SSD to more efficiently handle garbage collection, which would otherwise slow future write operations to the involved blocks. Because low-level operation of SSDs differs significantly from hard drives, the typical way in which operating systems handle operations like deletes and formats resulted in unanticipated progressive performance degradation of write operations on SSDs. Trim was introduced soon after SSDs were introduced. ( April 2020)Ī trim command (known as TRIM in the ATA command set, and UNMAP in the SCSI command set) allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered to be 'in use' and therefore can be erased internally.

This also means that any formulation of wins and losses would land team 1 in a division spot. The number here implies that team 1 has a magic number and is left with 12 games. If you want to find the magic number of team 1, we need to follow the procedure as follows: Let us assume that Team 1 is 84-78, and 12 games are left out. Let us look at an example here to understand how a magic number is calculated. When the magic number is zero, it means that the team has clinched a division/wild card position. When the magic number is one, it means that the team has tied with its rival team in the playoff. Zero values can happen only during the season’s start, as no winners and losers have decided yet. In every regular season, a team plays 162 games, and the magic number is calculated as follows: The rule of thumb is that the magic number automatically sets to 163 at the season’s beginning. Magic number = Games remaining + 1 – (Losses of the rival team(in second place) – losses of the team staying ahead) Here is the formula to calculate the magic number in MLB. A magic number of one implies the presence of a tie, while zero means a victory. How Is MLB Magic Number Calculated?Īdd one to the games to be played and subtract the number of losses and wins. This stat is an eye-opener to teams and evaluators. The magic number also lets identify the number of losses and wins to achieve a wild card spot. During this season, the Yankees had their magic number decreased to four, which meant that the Yankees would win or Red Sox would lose. Has magic number emerged recently? It was first applied in the 1947 season between Red Sox and Yankees. Whenever the number drops by one, it implies that the team has won the game. When teams compete in the season, it is essential to plan strategies on the go to maximize wins and minimize losses. What does it imply? It is a number denoting the number of wins needed by a team to take over its rival. Magic numbers are widely pronounced every year during September as teams begin closing while clinching.
Linden Lab has elicited both compliments and curiosity for its unconventional corporate culture, which is based on a non-hierarchical system where employees are unusually self-directed and transparent in their work. In June 2014, Linden Lab confirmed that they plan to build a new virtual world.Īs of August 2015, Linden Lab are in beta tests of Project Sansar. In February 2014, Linden Lab announced that its new CEO was Ebbe Altberg, former COO of BranchOut. Rod Humble, appointed CEO in December 2010, announced his departure on Facebook on 24 January 2014, stating that he would be leaving Linden Lab to pursue founding a new company that will "make art, entertainment and unusual things!". In January 2013, Linden Lab purchased the game Blocksworld for iPad, a shared virtual world built of blocks. In September 2012, Linden Lab announced two new products: Creatorverse (for iPad) and Patterns (gaming)|Patterns]] (for Desktop applications). As a result, the initial objective-driven, gaming focus of Second Life was shifted to a more user-created, community-driven experience.< That effort would eventually transform into the better-known, user-centered Second Life.ĭuring a 2001 meeting with investors, Rosedale noticed that the participants were particularly responsive to the collaborative, creative potential of Second Life. That vision soon morphed into the software-based application Linden World, where computer users could participate in task-based games and socialization in a 3D online environment. In its earliest form, the company struggled to produce a commercial version of "The Rig," which was realized in prototype form as a clunky steel contraption with several computer monitors that users could wear on their shoulders. His initial focus was on the development of hardware that would enable computer users to be fully immersed in a 360 degree virtual reality experience. With the help of a financial windfall that he reaped from his time at RealNetworks, Rosedale formed Linden Lab in 1999. While at RealNetworks, Rosedale's ambition to create a virtual world was resurrected and recharged by technological advances in computing and his attendance at the popular music and arts festival Burning Man. Rosedale's strong coding skills eventually resulted in the creation of a video compression technology that would later be acquired by RealNetworks, where he was made CTO at the age of 27. The company's transition from scrappy upstart to success is detailed in the book The Making of Second Life written by former employee Wagner James Au.Īlthough many people have assumed that the inspiration for Second Life originated from Rosedale's exposure to Neil Stephenson's novel Snow Crash, he has suggested that his vision of virtual worlds predates that book and that he conducted some early virtual world experiments during his college years at the University of California San Diego, where he studied physics. The company's name comes from Linden Street, where the company was originally based. chairman of Linden Lab, accepted the award.Īlthough Linden Lab's Second Life platform was not the first online virtual world, it has gained a large amount of attention due to its expanding user base and unique policy that allows participants to own the intellectual property rights to the in-world content they create. The award was given at the 59th annual Technology & Engineering Emmy Awards. In 2008, the company was awarded an Emmy for Second Life in the user-generated content and game modification category. The company's founder and original CEO is Philip Rosedale, a former CTO of RealNetworks, one of Time Magazine's 100 Most Influential People in The World in 2007. If you want to have a yes/no system, here is the code.The company, founded in 1999, employs numerous established high-tech veterans, including former executives from Electronic Arts, eBay, Disney, Adobe Systems, and Apple. This is GoldenSpartanGamer from blocksworld. Does anyone know how to use the buttons I spoke of before? Please post them in the comments. This is Rocket Science Productions® from Blocksworld. I know there are more where you can make the speak buttons activate two different things, but unfortunately, I don't know how to do them. To create a button in the speak button you will add, and you can place your text inside to display the text in the button. To have a player's name in the text, add /name/ Unlike Vista, XP and lower Windows versions, when you use a whole disk encryption product on Windows 7, or installing a dual boot, you will notice that Windows 7 automatically creates a 100MB system reserved partition, 24MB contains actual data the rest is there for future use like Bitlocker or system restore, this partition is hidden by Windows and only visible using a live CD or through DiskCryptor or Truecrypt interface. Using DiskCryptor keyfile for full disk encryption is something possible and not supported by Truecrypt, a keyfile will thwart dictionary attacks on your passphrase but this keyfile can not consist of anything it has to be a 64 byte file generated by DiskCryptor. Unlike Truecrypt, DiskCryptor bootloader is highly configurable, I have my own (Ascii) logo at logon and I instructed DiskCryptor to time out after 30 seconds of inactivity at which point the computer reboots, other options like halt and exit to BIOS are possible. When using special signs in your password be aware that in booting up your computer the keyboard has a US layout that will not correspond with a non US keyboard, I searched for a photograph of US keyboard layout on the Internet to make sure there would be no mistakes about what keys to pres. Truecrypt will ask you to enter your password after rebooting your computer before encrypting your operating system, DiskCryptor will not, it assumes you entered the passphrase correctly twice as asked and did not make any mistake. You can benchmark ciphers in Truecrypt too but since only AES can be used for full disk encryption there is no point in doing it. DiskCryptor download is a tiny 750Kb, after installing it you will need to reboot the computer, you might notice that its 64bit drivers come signed by the ReactOS foundation a non for profit organization assisting open source projects not able to acquire an expensive signing certificate to distribute Windows 64bit drivers.Įncrypting my Windows 7 Home Premium 64bit OS, with a fairly powerful Intel i5 2200Hz (quad core) absorbed very low CPU, a steady 7% of the available resources, it took me 20 hours to encrypt a 1TB hard drive, it would have been considerably quicker using just the AES algorithm instead of the cascade algorithm I selected.ĭiskCryptor lets you know how long it will take to encrypt your operating system, you can still work with your computer while it is being encrypted, I advice you to temporarily disable power management in Windows and set it to always on, Windows will not notice the hard disk being encrypted and send the OS into hibernation mode believing the computer is inactive, if this happens full disk encryption will stop and only resume once you switch the computer back on, I have found this problem to occur with both DiskCryptor and Truecrypt, more of a Windows problem than to do with the full disk encryption software.ĭiskcryptor lets you benchmark the encryption ciphers ( Tools>Benchmark) if you have a low spec CPU and are in a hurry you can choose the cipher that performs best in your system, AES was the quickest for me, by quite a lot of difference in contrast with Twofish and Serpent, once the OS has been encrypted it doesn’t matter what cipher you used to encrypt it, performance will be the same. May work for Java, but I can't test that. You can also travel to the worlds end using this nifty command: Tell us what YOUR favourite commands are in the comments below! Weve already seen that /clear without any arguments removes everything from your own inventory. Just remember not to use the nbt tags that are generated. Alternatively, you can also enter the commands in the command blocks, which are used to automate the activation process of in-game commands. You can also use tilde (~) or caret (^) notation with a number to express relative coordinates offset from your current position, with the notation by itself representing ~0 or ^0 ie no offset. The tellraw command is used to add JSON commands to a private message. If you are on a multiplayer server, the sound will be audible to other players too, but within a limited range. Submit an entry to ScreenSpace! All rights reserved. If not specified, defaults to the position of the command's execution. Caret offsets are based on the direction the player's head is facing along left, upward, and forward axes, so ^5 ^ ^-5 would be 5 blocks left, 0 blocks upward (same height), and 5 blocks backward. This Minecraft Bedrock command teleports entities to random locations in a Minecraft world. You can change the Minecraft weather using time modification and its toggle, but most players stick with this Minecraft Bedrock command.

The best thing about PowerPoint is that it allows you to customize your presentations as much as you need. Moreover, according to one mode of the present invention, there is provided a communication device supplying common data to a plurality of devices, comprising: a generation unit that generates a session key a reception unit that receives public keys from the devices a first encryption unit that encrypts the session key using the public keys corresponding to the devices, received by the reception unit a first transmission unit that transmits to the devices the session key encrypted using the first encryption unit a second encryption unit that encrypts the common data using the session key and a second transmission unit that transmits to the devices the common data encrypted using the second encryption unit. It is an object of the present invention to carry out communication parameter exchange between a plurality of devices at high speed.Īccording to one mode of the present invention, in order to accomplish the above-mentioned object, there is provided a communication system including a master device and a plurality of slave devices, wherein the master device comprises: a generation unit that generates a session key a unit that receives public keys from the slave devices, encrypts the session key using the public keys and transmits the encrypted session key to the slave devices and a data transmission unit that encrypts data using the session key and transmits the encrypted data to the slave devices and each slave device comprises: a decryption unit that transmits the public key to the master device, receives the session key encrypted using the public key and decrypts it and a data decryption unit that receives data encrypted using the session key from the master device and decrypts it using the decrypted session key. Therefore, other slave devices must wait until the processing by the master device is complete, and the time it takes for all the slave devices to complete wireless parameter setting is prolonged depending on the number of times the master device decrypts the session keys. However, when wireless communication parameters are set in a plurality of devices, no other processing can be performed simultaneously when the master device performs such processing, and therefore, master device functionality ends up being occupied by a single slave device. Therefore, processing (heavy-load processing) involving decrypting data encrypted with a public key using a private key corresponding to the public key has been performed by the master device. When the decryption is over, the slave device acquires and sets wireless parameters. By doing so, when the slave device receives the wireless parameters encrypted using the session key, it uses the session key for decryption. When the decryption is over, wireless parameters are encrypted using the session key and transmitted to the slave device. On the other hand, when the master device receives a session key encrypted using the public key, it uses the private key for decryption. Here, when the slave devices receive the public key, they encrypt session keys using the public key and transmit them to the master device. The setting of wireless parameters is initiated when the master device transmits a public key to the slave devices. In conventional automatic parameter setting methods, a master device such as an access point, which operates as a master, has a set made up of a public key and a private key, and slave devices, which function as slaves, generate session keys. The demand for communication between a plurality of terminals on such ad hoc networks is on the increase and methods for automatic setting of parameters on a plurality of terminals are required (see Patent document 1: U.S. Moreover, in recent years, communication is also more frequently conducted over so-called ad hoc networks, in which terminals communicate with one another directly over a wireless LAN without passing through an access point. has been implemented as an actual product. For instance, a method for automatic transfer of wireless parameter settings between an access point (relay station) and a station (terminal) from the access point to the station by means of a simple operation, etc. Because of the complexity of these setting operations, methods have been proposed for automatically performing them between terminals. When using wireless LANs conforming to the IEEE 802.11, users have to set wireless communication parameters, such as network identifiers (ESSID), encryption methods, cryptographic keys (encryption keys), authentication methods, authentication keys, etc. The present invention relates to a communication system including a master device and a plurality of slave devices, to a communication device, and to a processing method therefor.

High profile technology companies like Sony, HTC, Samsung, and telecommunication companies like Vodafone, SingTel, and O2, and tech Intel, Cisco, VMware, Microsoft, Google, Linksys, Dlink Epson, MSI, and Akamai were some of the companies that were on the target list of the malware.Īccording to Cisco Talos report, the malicious code was intended for a sophisticated supply chain attack to infect a vast number of machines. The security report also mentioned the attackers were only interested in a specific subset of PC users who worked in tech firms. Though the CCleaner malware infected 2.25 million PC’s between the period l August 15, 2017, to September 15, 2017, the main target of the malware was specific tech firms in US, Japan, Germany, Taiwan, and the UK. The company has mentioned the versions of CCleaner and CCleaner Cloud are infected and has urged the users to upgrade to version 5.34 or higher. The CCleaner malware has affected around 2.27 million users.Īccording to the report, hackers have injected malicious code of data harvesting software that piggybacks on the CCleaner installer program. Using these tools will certainly help improve the performance of your computer, but use them cautiously and never remove or delete something that you don’t understand or know for sure what it is.According to reports from leading security companies, hackers injected malicious code into CCleaner, a popular PC cleaner tool. Similar to a cluttered desk, a cluttered registry can reduce productivity and performance. When you delete a program or uninstall something, registry entries can be left behind. All programs create registry entries into the computer. CCleaner does offer something the others don’t, and that is cleaning up your registry. If your computer is just more generally “slow” CCleaner can give you some insight into why and help you fix it. If you know specifically you have one of the problems listed above, those are great tools to use. It can perform some of the tasks the other tools can but in a different way. Piriform CCleanerįor a more broad maintenance tool, CCleaner is a great option. Be especially careful removing some of these programs that autorun, as they may be required services for the particular program to run. When you run the utility it will show you the different programs that are starting up with your system. Autoruns is a great way to get a handle on all of the items affecting your start-up time. As you continue to add software, your computer can seriously start to take forever to boot up. AutorunsĮach piece of software you install on your computer can add items to your start-up. Just about all of the items that Malwarebytes finds can be removed, but again, if you have a question about a particular item, make sure to consult a professional before you remove it. When you suspect you have a virus, running a Malwarebytes scan can clean up most of the simple viruses that infect your system. The biggest symptoms that you have a virus are multiple popups when browsing the internet, and websites being slow to load. Viruses can plague computers no matter how careful you are. You can use Treesize on any drive, internal and external, to find out what could be using the most space.
