Offering a meagre 1Gb of storage, Bitbucket is among the most expensive git repository hosts around, and therefore has never enjoyed wide adoption among small developers. This will set you up with an account with Bitbucket - and getting you signed up to Bitbucket is undoubtedly the main reason for Atlassian to make this app free. In order to use the app you are required to setup an account with Atlassian. If you spend a lot of time coding then it's worth trying several. But they each have their strengths and weaknesses. I have found SourceTree to be the best GIT GUI for me, at any price. And there's also a "copy commit hash" menu item, which is useful for starting an interactive rebase on the command line. Fortunately the contextual menu has a Copy command that does the job. The one bug I currently know about is that if one selects text from the commit info pane and types ctrl-C, it ignores the selection. It has occasional cosmetic bugs, and Atlassian can be slow to fix those. Overall I have found it to be quite robust. SourceTree can also show the text of an annotated tag - and that is another thing that few, if any, other GIT GUIs can do.Īlso I find the history layout very efficient: a single window shows commits, uncommitted changes and the diff between any two commits (or your uncommitted changes and any commit). And it does this in a very natural way: the current state is a node, just like each commit. ![]() SourceTree is the only GUI I have found that can show the difference between uncommitted changes and any commit. I have tried Tower, Fork, Sublime Merge, and several others. SourceTree continues to be my favorite GIT GUI, especially for viewing history and changes (which is my main use for a git GUI I use the command line for most other things). I have found SourceTree to be the best git GUI for me, at any price. But occasionally I just want to say "use my local copy" or "use the remote version" and in that situation I find it difficult to know which is which. Its merge conflict support is just fine for working through a file line by line: you can use any 3-way merge tool, such as Apple's FileMerge. ![]() One weakness is resolving merge conflicts using "Theirs" or "Mine". Last time I tried Tower and Sublime Merge they could not. SourceTree and Fork can both show the annotation for a tag. I find the history layout very efficient: a single window shows commits, uncommitted changes and the diff between any two commits (or your uncommitted changes and any commit). No other git GUI I have tried does this the others only show the diff between the uncommitted state and HEAD, and you have to change views to see it. I own Fork and have tried Tower and Sublime Merge.įor me, the standout feature for SourceTree is that it treats the current uncommitted state as just another node in the history, allowing you to easily compare uncomitted changes to any other commit. They should reword that as "automatically butcher all whitespace in your Mac/Linux source files" which is a much more accurate description of that that option does.SourceTree is my favorite git GUI, especially for viewing history and changes (my main use for a GUI I use the command line for most other things). Make sure you UNCHECK "Configure automatic line ending handling by default (recommended)." You can choose any directory you want but I like shorter paths that don't have spaces in them for easier MinGW/MSYS compatibility.ĭuring the installation process there is an option to connect your Github account, which you probably want to do.ġ.B) DO NOT configure automatic line ending handling. Seriously Windows, why do you still use the \r character? It boggles the mind. ![]() Since I code on both Windows and Unix, I need some special settings that make sure that git doesen't corrupt my files and start adding \r characters all over the place. Either that, or you haven't taken the time to try out SourceTree. If you are still running git by hand, you are insane. SourceTree is an amazing tool to help you manage Git repositories.

But the attack speed will continue to update while you channel as Momentum is gained and lost, so as you gain additional Momentum based on how long you channel for the skill will speed up, but when you reach maximum and lose it all, the skill will slow down, so you don't get to benefit from the maximum amount for any length of time, since you never get to keep maximum Momentum.Ample time is also dedicated to challenging platforming, with environments full of moving platforms that need to be deftly maneuvered with quick timing. Lords of Exile ist ein beliebtes Steam-Spiel, das von Squidbit Works entwickelt wurde. Because it's accounting for the momentum it's going to generate, you'll see this reflected in the attack time of the skill when the gem is socketed, before using it.Ĭhannelling attacks do dynamically update attack speed during their use, so initially work out to basically the same result in that when you use them you'll immediately gain 1 Momentum and the attack will update it's speed to account for that Momentum, so you'll start out with attack speed equivalent to 1 Momentum rather than 0, just like the non-channelling case. Lords of Exile is a 8-bit side-scrolling action platformer set in the far Lands of Exilia where a cursed knight makes his way to the revenge. The attack which brings you to maximum Momentum will benefit from that maximum amount of Momentum, despite it being lost immediately to grant Swiftness. Since using the attack always grants 1 Momentum, the attack accounts for the momentum it's generating, and will benefit from that Momentum, so the first attack will have the attack speed for 1 Momentum (the one it generates), rather than 0. For most non-channelling attacks, attack speed is calculated only once when you start the attack. ![]() One of the big reasons people own SPG is for their dividend but with the recent news, there could be up to a 50% cut. In the video below I go over the setups for the Simon Property Group’s stock from the section above because it is sometimes easier to see what I am trying to explain through a quick video. Simon Property Group long SPG Stock Price – Video Review Gaps love to be filled so keep that in mind there are a couple to be filled to the upside so that could be a magnet to help move the price upwards. It doesn’t guarantee it but is one of the factors I look for in a trade. This is a good barometer to see if the price could be at a turning point which it may be. The shorts will have taken over.īut if the price can hold without going too far under $60 then this long setup remains valid.Īlso, note that the Money Flow Index (MFI) is coming out of the oversold area. This setup would become null if the price continues to move down to around $52.00 because then the 61.8% Fibonacci level would be too beat up to consider that a level that held. The current target for this setup is $110.09. It was triggered when the price hit the 38% Fibonacci retracement level and found support at the 61.8% level. In the picture below we are looking at a long setup for the Simon Property Group. So this is a valid short setup on the daily time frame that the SPG stock is currently located. If the price does go down and hit the price target of $8.52 then the Simon Property Group has a lot bigger issues going on. Since then the price has moved back down and is currently sitting at $68.93. When the price does this then this locks in a potential short setup. You can see how the price came back up and retraced to the 38.2% Fibonacci retracement line. ![]() In the picture below we are looking at a short setup using the daily time frame. What I mean by that is if I would purchase the stock so please don’t take this as professional financial advice because it is only my opinion on how I trade.

In fact, on the sphere, there are no parallel lines. You saw the two vertical lines (both perpendicular to the equator) are parallel at the equator but end up meeting each other at the North Pole. ![]() Now, using the example at the beginning of this section (the “triangle” on the sphere), you may be able to see that this postulate is not true on the sphere. The original statement is weird, right? This is exactly what caused the controversy and, eventually, a revolution. (Originally this statement was more like this: “If two lines both crossing another line form two interior angles on the same side whose sum is less than two right angles (180 degrees), then the two lines, when extended indefinitely on that side, will eventually meet.”) Given a line L and a point P that is not on the line, there is one and only one line through P parallel to L. (And they’d better be obvious to everyone so that no one would question them.) Here are the first four:Įuclid's Fifth Axiom (Parallel Postulate) Just as you cannot define every word you use (because each definition uses other words, each of which also needs to be defined using other words), you cannot prove everything some statements must be assumed true at the beginning. What is an axiom? It is a (self-evident) statement assumed true without proof. In fact, he started with only five axioms. That whole thing-which is the fundamental structure of mathematics-was first established by Euclid.Īnother amazing accomplishment of Euclid was that he proved tons of propositions-465 to be exact-based on a very small number of assumptions. If you remember your high school geometry, you may recall memorizing postulates (general assumptions) and proving theorems based on known properties and other theorems. Well, for one thing, it was the first book that laid the foundation of deductive logic-to prove general statements (called propositions) by definitions, general assumptions, and already known propositions. He could have been quite wealthy all the royalties he could have earned (except he would not have cared-there is a well-known story of Euclid embarrassing and humiliating one of his students who wanted to know what he would gain by learning geometry). It’s too bad that the notions of copyrights and intellectual properties did not exist back then. It was the standard book in geometry for over 2000 years, and there are over 1000 editions of the book in hundreds of languages. This book may be the most widely read treatise in world history because no other books have been read longer or by more people, with the exception of the Bible. The reader is encouraged to find out more by doing a search under “non-Euclidean geometry.”Įuclid, who lived around 300 B.C., is best known for his book The Elements, a 13- volume masterpiece laying the foundations of geometry (and some number theory as well). Here, a very abbreviated version of the story is presented. What many experts feel is offensive and repugnant may actually be true.What stands the “test of time” may not be absolutely true.Common sense could be the greatest obstacle to finding truth.The story is worthy of a movie or a play. The conception and arrival of non-Euclidean geometry involved three mathematicians-one very famous and two completely unknown. This subject, “Euclidean geometry” (the type of geometry you studied in high school), was so popular and dominant that no one, for over two millennia, doubted its truthfulness, questioned its authority, or thought of coming up with an alternative. You see, Euclid (who lived over 2300 years ago!) wrote a textbook that was so popular that practically every educated person in the world used it to study geometry for the next 2000 plus years. ![]() It was truly a ground-shaking event, not only in the history of mathematics and but also in philosophy. The birth of non-Euclidean geometry was REALLY a big deal. It is called "Non-Euclidean" because it is different from Euclidean geometry, which was developed by an ancient Greek mathematician called Euclid. Image is used under a CC BY-SA 3.0 license. In a small triangle on the face of the earth, the sum of the angles is very nearly 180°.
