![]() The values in the Fibonacci sequence work well because they roughly correspond to Weber’s Law. (I know I can’t.) And if you could, it would mean you should be able to distinguish between a 1.00 kg weight and a 1.05 kg weight, as that would also be 5%. The difference between 20 and 21kg, however, is only 5%. You can probably distinguish the weight of items that differ by 100%. The difference from one to two kilograms is 100%. ![]() Weber’s Law states that the difference we can identify between objects is given by a percentage. But you would have a much harder time identifying the heavier of the two weights. They are the same one kg difference as the one and two kg weights. Imagine instead being handed a 20kg weight and a 21kg weight. The two kg weight will feel noticeably heavier. With one in each hand but not able to see which is which, you can probably distinguish them. Imagine being handed two weights-one is one kilogram (2.2 pounds) and the other is two kilograms (4.4 pounds). It’s because numbers that are too close to one another are impossible to distinguish as estimates. Years ago I began having teams estimate with a modified Fibonacci sequence of 1, 2, 3, 5, 8, 13, 20, 40 and 100. The traditional Fibonacci sequence is 1, 2, 3, 5, 8, 13, 21 and so on, with each number the sum of the preceding numbers. If you’ve estimated with Planning Poker, you may very well have used cards with either the Fibonacci sequence, or a modified Fibonacci sequence.

![]() (Basically I re-implemented a subset of the Alto file system using the raw disk.)Įrasing the password flag in this block makes the disk bootable without the password.Īfter implementing this, I realized there's a short cut. So once we've found the first block, we can follow the pointer to find the second block. In the Alto file system, each disk block has pointers to the previous and next block. The file system stores a directory as the name of each file along with the disk address of the file's first block.īy reading the directory as raw data and interpreting it, we can find the location of sys.boot. The tricky part is finding where this word is on disk. The password protection can be disabled by clearing the flag word inside sys.boot, which is the 128th word in the second block of sys.boot. The next four words are the salt, and the final four words are the password hash itself. If the password flag is set, the boot program requires a password before proceeding. The first word is a flag indicating if the disk is password protected. The Alto boots from disk by running the file sys.boot this file decides if a password is required for boot, based on the 9-word password vector stored inside the file. There's a way to disable the password on disk, gaining access to the file system. x is a one-word value generated from the password string and y is a two-word value from the password string, both generated byĬoncatenating characters from the password. Where a is the time salt and b is the user name salt. The Alto's password hash algorithm is pretty simple: 4 The password hash is 4 words (64 bits) long. The Alto uses four words of salt with the password (two words based on the password creation time and two words based on the user name). The source code for the Alto's password algorithm reveals how the password hashing is implemented. Like Unix, the Alto used salted and hashed passwords. (Of course you need to store the salt along with the hash in order to check passwords.) 2 Since different users will have different salt, the hashes will be different even if the passwords are the same. One problem with hashed passwords is if two users have the same hash, then you know they have the same password.Ī solution (invented in Unix) is to hash some random bytes (called salt) along with the password to yield the stored hash. And if anyone sees the hash, there's no easy way to get the password back. When the user inputs a password, you hash it through the same function and compare the hashes. ![]() Instead of storing the password, you hash the password through a cryptographic one-way function and store the hash. Most systems use a solution invented by Roger Needham in 1967. Storing passwords in plain text is a very bad idea, since anyone who can access the file can see the password. Password protection is described in the Alto User's Handbook page 5. ![]() This ‘thumb,’ however, is not truly opposable, and polydactyl cats are not able to open their own tins or perform any other very un cat-like feats!Normal cats generally have eighteen toes altogether- four on the pads of each paw, and an additional two dewclaws slightly higher up on the front legs. ![]() If the word ‘polydactyl’ is one that you have never heard before, you could easily be forgiven for thinking that it is the name for some kind of dinosaur, or something equally exotic! However, the reality of the matter is somewhat different, although also rather unusual- the word ‘polydactyl’ is taken from the Greek words for many (poly) and fingers (dactyl), and refers to a person, or animal, that has extra fingers, toes or other digits on their hand or foot.Polydactyl cats, therefore, are cats that have an extra toe on one or more of their feet, leading to them sometimes being colloquially referred to as ‘mitten cats’ or ‘boxing cats,’ among many other terms! Often the positioning of the extra toe gives the appearance to the cat of having four fingers and a thumb, in the same way that people do- So, do polydactyl cats really have opposable thumbs? What does it mean to own a polydactyl cat, and is polydactyly (the condition of being polydactyl) a problem for cats? Read on to find out! What exactly is polydactyly?įeline polydactyly is a genetically inherited physical anomaly that leads to the cat in question being born with extra toes, usually alongside of the regular toes in the position in which there would, in animals such as people, be a thumb. ![]() This is probably the closest you will get on Linux to the speedy video download capabilities of Download Accelerator Plus.

You’ll also find barrels throughout the levels granting you access to one of DK’s faithful companions: Diddy Kong, Dixie Kong and Kranky Kong. The gameplay remains pretty much exactly the same as its Wii U ancestor – DK can run, jump, climb and roll throughout the levels with grace, and you’ll often need to make use of his powerful arms to pound the ground in order to reveal secret passages and collectibles. The variety throughout the game is seriously impressive and it never gets dull. Fear not, though – throughout Tropical Freeze you’ll be rolling across burning savannahs, plunging the depths of the sea and even traversing across some giant fruit. Additionally, considering the game’s subtitle and the threat of perpetual winter in the plot, you’d be forgiven for thinking that the entire game take’s place in snowy environments. Before long, the entire island is buried beneath snow and ice – but what happened?! The opening cinematic does well to set up the general premise, but the story as a whole is largely insignificant. It all kicks off during Donkey Kong’s birthday party, and just as our simian hero is about to blow out his birthday cake candle, a gust of wind extinguishes the flame and a snowflake floats into view. Every single level is absolutely jam-packed full of secret collectibles and varied enemy design, it’s easy to appreciate the passion Retro Studios has put into the title. The level of sheer ingenuity remains intact with the Switch version – in fact, the ability to play the game on the go only further highlights just how fantastic it really is. I’d go so far as to say that it’s one of the strongest platform titles in recent memory, easily beating out Nintendo’s own ‘New’ Super Mario Bros franchise and possibly even Ubisoft’s Rayman series – it’s that good. If somehow you didn’t play Tropical Freeze on the Wii U, or its predecessor Donkey Kong Country Returns on the Wii/3DS, you’ll be thrilled to know that it delivers practically everything you could possibly wish for in a side-scrolling platform title: bold visuals, sharp gameplay, varied levels, menacing bosses and a steep but fair difficulty curve. But how does the experience hold up after four years? Let’s find out… ![]() ![]() Its release on the Switch is largely exactly the same experience as before, bananas ‘n’ all, but with a few significant additions and alterations that both newcomers and returning players will appreciate. Originally released on the Wii U back in 2014, Donkey Kong Country: Tropical Freeze continues Retro Studios’ streak of high quality games following their initial stint with the Metroid Prime series. One could argue that their target audience has always been – and always will be – children, but for the millions of fans who have grown up alongside tent-pole franchises such as Mario and The Legend of Zelda, it’s safe to say that they’re after something a little bit more taxing. One of the main criticisms directed at Nintendo in recent years is that they tend to make their games a bit on the easy side. ![]() Immediately on your left is a blue building complex with its own parking lot our office is right by the flagpole.
