6/30/2023 0 Comments Quake 3 inverse square root![]() ![]() Remember, kids: just because it was fast in the 90’s doesn’t mean it still is! That said, it’s still a fun bit of code to pick apart and understand how it works. Evidently the additional division instruction to evaluate 1/sqrt(x) still blows the hand-spun (and less accurate!) version out of the water at most optimization levels. The single-player mode is played against computer-controlled bots. The third installment of the Quake series, Arena differs from previous games by excluding a story-based single-player mode and focusing primarily on multiplayer gameplay. Its origins aren’t completely clear and they can be traced back way before Quake III was launched in 1999. Since we have now put our number that were trying to find the inverse square root to, y, as its bit representation, we have effectively stored approximately. While it was initially attributed to Carmack, he denied having written it. It became famous when the Quake III source code was made public around 2005. Nope! If you dig into the disassembly, it turns out that gfortran on my machine makes use of the sqrtss SSE instruction for square-root. Quake III Arena is a 1999 multiplayer -focused first-person shooter developed by id Software. The fast inverse square root is a clever algorithm that approximates 1/sqrt (x). The function uses some clever bit hacking to approximate the inverse (or reciprocal) square root of a 32-bit oating point number quickly. 3KB This is a implementation of the fast inverse square root function from quake 3.

XRP has seen a slight price bump as news of the investment spreads. Largest funding rounds point to enterprise applications FocusFollowing Ripple’s mega-round, 3 of the next 4 largest blockchain deals of the quarter went to companies looking to streamline business processes (the exception being Layer1).Figure Technologies raised 103M to continue growing its blockchain-based platform Provenance, through which the company provides home equity loans with. Related: Ripple Files Last Bid to Dismiss XRP Securities Lawsuit Before Court Meeting Earlier this month, Ripple moved to have the case dismissed, saying, along with other arguments, even if XRP were a security, the investor plaintiffs brought their case far too late for it to proceed. Ripple will be in court next month, defending its motion to dismiss a lawsuit claiming its sales of XRP were an unregistered security issuance. Blockchain payments firm Ripple has announced a 200-million Series C share buyback, a decision that will take the San Francisco-based tech firm to a record-high valuation of 15 billion. In its last financial report, Ripple said its total XRP sales for the third quarter of 2019 were worth $66.24 million, up from $251.51 million in the previous quarter. ![]() As part of the deal, MoneyGram will utilize Ripple’s products for cross-border settlements. It also partnered with MoneyGram, taking a near 10 percent stake in the remittance firm. Highlighting what it called its “strongest year of growth to date,” Ripple said its RippleNet payments network grew in 2019 to over 300 clients. The new stakeholders will further provide “invaluable industry insight and expertise” as Ripple grows its business, according to the announcement. The investment will allow the firm to further draw new international talent and “better serve” customers and partners, the firm said. ![]() The summary judgment motion remained under seal as of Friday.Related: Ripple’s Revamped Xpring Platform Looks to Boost XRP Development “With trial quickly approaching, the costs and inefficiencies associated with disrupting this case’s timeline, particularly when an appeal on a final judgment would be more appropriate for this contractual interpretation dispute, outweigh the potential benefits Tetragon asserts.”Īdditionally, Law360 also revealed that Ripple has taken initiative for summary judgment and also termination of the case after the rejection of the prefatory order, “with trial still scheduled for March 25 and 26. “Tetragon’s application does not identify any particular aspect of the court’s interpretation that was erroneous, much less a specific error on a substantial issue of material importance, qualifying the decision for state Supreme Court review before the case is decided by summary judgment or trial.”Īlso, Zurn reaffirmed the decision made on March 05 by saying that “Tetragon was not reasonably likely to prevail on the merits because neither the Wells Notice nor the enforcement action constituted a Securities Default pursuant to the plain language of the shareholders’ agreement.” Additionally, Zurn determined that XRP’s standing as a security is judged by the district court of the US and not by the filing by the SEC. Judge Zurn detailed in a 12-page decree that Tetragon was unable to demonstrate that a request of the tentative order requires “more than review of a contract interpretation, a category that the Chancery Court has generally deemed unworthy of interlocutory appeal.” ![]() Nevertheless, the biggest contributor to a Series C financing round that saw Ripple amass $175 million filed case on Ripple to repurchase its tokens following the filing of lawsuit by SEC, stating that it “triggered the risk of irreparable harm.”Īs Law360 states, the Chancery Court of Delaware has also objected Tetragon’s plea for an appeal with the state Supreme Court. The UK headquartered asset administration company controls only 2% of Ripple’s equity. Hence, Judge Morgan Zurn did not accept Tetragon’s demand for a prefatory injunction, and boosted the earlier enforced injunction prohibiting the sale of XRP. The court considered Tetragon’s assertion that a “securities default” is false, as there is presently no formal decree on the standing of XRP. After the court has passed a decree on March 05 that Tetragon is not eligible for stock redemption from Ripple, with rejection of appeal from Court of Chancery of the State of Delaware. Ripple Labs has received another success in its legal case with Tetragon Financial Group Limited.

You draw a universal set while solving math equations. It provides a better classification of real numbers in mathematics. Solving complex math equations is the reason why most mathematicians prefer using Venn diagrams to understand various concepts. It means that you can create complex diagrams without affecting data classification. You can group similar data into chunks it helps you easily identify intersecting information even if your diagram is complex. Venn diagrams make it easier to find the similarities and differences between opposing data sets. A universal set is a superset to every set included in the diagram.īetter classification and comparison of data through visual representation while keeping everything simple. This symbol represents the set that contains everything. This symbol depicts that the set does not have any elements. You can find the complement of set A by subtracting all elements of set A from the universal set. The symbols ∪ between the two sets represent all the elements in both sets.īy set A from set B, you get a solution set with elements of set A that are not in set B. It shows the elements that are only in both sets. The symbol ꓵ between two sets represents only similar elements. The letter A represents the circle with all the elements of set A in the diagram. There is an article to introduce Venn diagram symbols. The diagram represents the classification and comparison of data sets therefore, you only have to learn six symbols to get started. If we talk about the set theory, then you have to learn more than 30 symbols, but you can make a Venn diagram by only understanding the few basic symbols. It not only makes the visual presentation better the layout also makes it easy to understand the logic behind it. ![]() This triangle represents similar data in those three circles. When three circles partially overlap each other in a diagram, they create a triangle at the intersection area. Normally, you can use any number of circles in a Venn diagram, but the most commonly used type is the triple-circle diagram. That is why these diagrams are typically used for business presentations, logic studies, and mathematics. Using circles for the representation of data makes it simple to depict similarities between two or more factions. With the help of a Venn diagram, you can easily describe any relationship between two or more concepts. Overlapping circles represent the similarities, while detached circles represent the difference between sets or concepts. Each circle represents one particular set of data. It depicts relationships between two or more sets of data by using circles as an illustration. This is written as A ∩ B.A Venn diagram is a visual representation of similarities and differences between two or more concepts. The intersection of two sets A and B consists of all elements belonging to A and to B. The set V c in the first example can be represented on a Venn diagram as follows. ![]() This means that our description of the elements of a set is clear and unambiguous. Which we read as ‘S is the set of odd whole numbers less than 10’.Ī set must be well defined. Thus the set S above can also be written as The five elements of the set are separated by commas, and the list is enclosed between curly brackets.Ī set can also be described by writing a description of its elements between curly brackets. Which we read as ‘ S is the set whose elements are 1, 3, 5, 7 and 9’. The objects in these sets are called the elements of the set.Ī set can be described by listing all of its elements. We do a similar thing in mathematics, and classify numbers, geometrical figures and other things into collections that we call sets. For example, we speak of ‘a flock of birds’, ‘a herd of cattle’, ‘a swarm of bees’ and ‘a colony of ants’. English has many words for such collections. In our ordinary language, we try to make sense of the world we live in by classifying collections of things. A set is just a collection of objects, but we need some new words and symbols and diagrams to be able to talk sensibly about sets. ![]() 6/29/2023 0 Comments Twitter blue tick emoji text![]() ![]() ![]() Twitter removed blue ticks from inactive accounts in January 2021 as part of its new policy for verification. This is based on Twitter’s criteria for an active account. Opting for the private account option, where only your followers can see and engage with your content, automatically makes you ineligible for the blue tick. When you earn the blue tick on Twitter, your account is likely to experience faster growth as the verification badge signals to potential followers that this person's content might be more trustworthy, since they have gone through the verification process. When your followers know you have the blue tick, they can tell that anyone trying to contact them without it isn’t you. Plus, verification helps cut back on phishing. Users can also easily find your “official” account through search as verified accounts are more likely to show up in search results.

Your claims adjuster should help you document the flood damage for your claim, according to FEMA. "The adjuster should never ask you for money or collect your deductible amount," FEMA states.Īfter your inspection, your adjuster should give you more information about what else you need to do and what will happen next. While meeting with a claims adjuster, ask about getting an advance payment to help you start recovering and about increased cost of insurance. When you meet with your adjuster, they should give you an explanation of the National Flood Insurance Program Flood Claims Process, an inspection of your property where they will scope your loss by taking measurements and photos, an explanation of what an advance payment is and how or if you can get one, information on presenting your loss to your insurance company and a discussion about your policy coverage. According to FEMA, they should also provide you with their contact information. When meeting with a claims adjuster, they should show you official identification, such as a driver’s license, company ID and flood control number card. In addition, be sure to contact your local building department and floodplain administrator to get information on whether your property was substantially damaged and if a building permit is necessary. "It’s important to consult your adjuster or insurance company before you sign any agreement/contract with a cleaning, remediation, or maintenance contractor." "Contact repair services if the building’s electrical, water or HVAC systems are damaged," FEMA states. "For your building items, keep some samples (swatches) and also photograph items like water-damaged carpet (and or other flooring), wallpaper and drapes before disposing of them so you can show them to your adjuster during the inspection."Īfter taking photos and videos, immediately throw away any flooded items that pose a health risk, including perishable food items, clothing, cushions and pillows.

I did order again however because I did like the final product - its very light because its produced on styrofoam and it sticks directly to the wall because of 4 stickies on the back - dont know how long that stickiness will last - but it is convenient especially as I moved them around until I decided on final arrangment.Ī great way to get the pictures you love from your phone to your walls!! The pictures are cut off at the edges rather that resized to fit the 8x8 for example so even though I fit it as I liked it to be - I lost some of the edges of my pictures ( I only ordered edge style where the whole production is the picture - no frames - mainly so I dont loose anything of the picture) and when selecting the pictures I like on the app there is no option to size down ones picture to fit the frame - only enlarge if one wants to focus on part of the picture and cut off some.Īlso the app is not a long term account app - so every time I need to order I have to enter my information from scratch and I can not view or check status of a current or view past orders on the app which is very limiting. The customer service team are very good at responding to ones questions and emails - the produced final product is good quality for the price paid - a couple of limitations - sizes are 8x8 for frameless (edge) and some of picture I sent was still cut off and even slightly more cut off if one choses framing styles like bold or clean - the other two framing styles classic or ever result in an even smaller size for the print (6圆). ![]() The app is also super easy, all in all it took me 2 minutes to install it and order.” – Yulia M.Ĭontact our team any time at. “The prints are beautiful they are very easy to stick to the wall and to readjust if needed. ![]() We have used Mixtiles to order some of our wedding photos and we were happy with the products!” – James K.

These diminutive earbuds are far thinner than most true wireless earbuds and stay in place securely, so you can roll over and not worry about losing one. ![]() If you’re trying to rest next to a loudly snoring bedmate, near clamorously celebrating neighbors, or close to a construction site, the Anker Soundcore Sleep A10 earbuds physically isolate your ears from noise, and they can further mask disturbances by playing white noise and other sounds.

However, the headband-style design could interfere with hair bonnets, dental headgear, or nighttime skin treatments, and folks hoping to block external noise-such as the loud snoring of a partner-may find that the cloth isn’t isolating enough. The Bluetooth module and speaker drivers are easier to remove than the pieces in competing models, which makes washing the headband less arduous. You can stream audio wirelessly from any Bluetooth source (be it a smartphone, tablet, or TV), and the 24 hours of battery life means you’ll get a few nights of rest before needing to charge again.
