35,761,894 | 0 | <p>You are very confused about python data structures, you can't have keys in lists, you don't need a list of dictionaries with only one key.

26,846,968 | 0 | <p>If you think about the overall operation that you are trying to perform, it is really just a Wipe-and-Replace based on what you are passing in. According to your stated rules:</p> <ul> <li>if I send parameter with CrateID = 2 and FruitID = 4, I want it to add another row (<em>assumption is that no rows exist yet for CrateID = 2</em>)</li> <li>if rows already exist for CrateID = 2: delete all records where CrateID = 2 and then add new records I am sending in parameter, don't touch another CrateIDs</li> </ul> <p>Hence, you shouldn't be using <code>MERGE</code> for this. Instead, just do:</p> <pre class="lang-sql prettyprint-override"><code>DELETE fc FROM Fruits_Crates fc WHERE fc.CrateID IN (SELECT DISTINCT tmp.CrateID FROM #FruitCrates tmp); INSERT INTO Fruits_Crates (FruitID, CrateID) SELECT tmp.FruitID, tmp.CrateID FROM FruitCrates tmp; </code></pre> <p>Or, if most of the time the number of items that match exceeds the number of items that will be removed and added, you can take a more targeted approach:</p> <pre class="lang-sql prettyprint-override"><code>CREATE TABLE #FruitCrates (FruitID INT, CrateID INT); CREATE TABLE #Fruits_Crates (FruitID INT, CrateID INT); --DELETE FROM #FruitCrates INSERT INTO #FruitCrates (CrateID, FruitID) VALUES (2, 4); INSERT INTO #FruitCrates (CrateID, FruitID) VALUES (2, 6); INSERT INTO #FruitCrates (CrateID, FruitID) VALUES (3, 26); --DELETE FROM #Fruits_Crates; INSERT INTO #Fruits_Crates (CrateID, FruitID) VALUES (1, 4); INSERT INTO #Fruits_Crates (CrateID, FruitID) VALUES (2, 4); INSERT INTO #Fruits_Crates (CrateID, FruitID) VALUES (2, 8); DELETE fc --SELECT fc.*, '--' AS [--], tmp.* FROM #Fruits_Crates fc LEFT JOIN #FruitCrates tmp ON tmp.CrateID = fc.CrateID AND tmp.FruitID = fc.FruitID WHERE tmp.CrateID IS NULL AND fc.CrateID IN (SELECT DISTINCT tmp2.CrateID FROM #FruitCrates tmp2); INSERT INTO #Fruits_Crates (FruitID, CrateID) SELECT tmp.FruitID, tmp.CrateID FROM #FruitCrates tmp LEFT JOIN #Fruits_Crates fc ON fc.CrateID = tmp.CrateID AND fc.FruitID = tmp.FruitID WHERE fc.CrateID IS NULL; SELECT CrateID, FruitID FROM #Fruits_Crates; </code></pre> <p>Output:</p> <pre class="lang-none prettyprint-override"><code>CrateID FruitID 1 4 2 4 2 6 3 26 </code></pre> <p>Result:</p> <ul> <li>Row with CrateID = 1, FruitID = 4: <strong>left alone</strong></li> <li>Row with CrateID = 2, FruitID = 4: <strong>left alone</strong></li> <li>Row with CrateID = 2, FruitID = 8: <strong>removed</strong></li> <li>Row with CrateID = 2, FruitID = 6: <strong>added</strong></li> <li>Row with CrateID = 3, FruitID = 26: <strong>added</strong></li> </ul> |

40,503,235 | 0 | <p>To take a random (pseudorandom, to be accurate) number, you can use <code>Rnd</code> function. It gives you a value in range form 0 to 1. To get some particular number from range, you can <a href="https://www.techonthenet.com/excel/formulas/rnd.php" rel="nofollow noreferrer">use this solution</a>. So, to get a random number from your range of row 2 to last , you can do for example:</p> <pre><code>Dim LastRow As Long, rRow As Long LastRow = Range("A" & Rows.Count).End(xlUp).Row ' Last row based on column A rRow = Int((LastRow - 2 + 1) * Rnd + 2) </code></pre> <p>Now you need to take this 15 times, and be sure that you wont get the same row multiple times. We can use array, and store row numbers inside. Unfortunately, VBA has no function to check if some particular value is inside. We to do it by looping through the values. </p> <pre><code>Dim LastRow As Long, rRow As Long Dim rowArr(14) As Long Dim found As Boolean LastRow = Range("A" & Rows.Count).End(xlUp).Row For i = 0 To 14 rRow = Int((LastRow - 2 + 1) * Rnd + 2) found = False If i > 0 Then For j = i - 1 To 0 Step -1 If rowArr(j) = rRow Then found = True Next j End If If found Then i = i - 1 Else rowArr(i) = rRow End If Next i </code></pre> <p>No we have to check, if sum of values in random rows are equal to 12, and if not, loop the whole process. The whole thing will look like:</p> <pre><code>Dim LastRow As Long, rRow As Long Dim rowArr(14) As Long Dim found As Boolean, mainCriterium As Boolean Dim sumOfValues As Double mainCriterium = False Do While mainCriterium = False LastRow = Range("A" & Rows.Count).End(xlUp).Row For i = 0 To 14 rRow = Int((LastRow - 2 + 1) * Rnd + 2) found = False If i > 0 Then For j = i - 1 To 0 Step -1 If rowArr(j) = rRow Then found = True Next j End If If found Then i = i - 1 Else rowArr(i) = rRow End If Next i For i = 0 To 14 sumOfValues = sumOfValues + Range("G" & rowArr(i)).Value Next i If sumOfValues = 12 Then mainCriterium = True Loop </code></pre> <p>When loop will end, you gonna have array <code>rowArr</code> containing 15 rows, which sum of values in column G is equal to 12.</p> |

37,001,358 | 0 | <p>According to <a href="http://facebook.github.io/react/docs/component-api.html#setstate" rel="nofollow">React's setState doc</a>:</p> <blockquote> <p>Performs a shallow merge of nextState into current state</p> </blockquote> <p>This means you should provide a valid <code>nextState</code> object as argument to the method. <code>{info.merchandise.label: "New Label"}</code> is not syntactically correct, that's why you get an error.</p> <blockquote> <p>Treat this.state as if it were immutable.</p> </blockquote> <p>This simply means that if you want to change some property inside the state object, you should not mutate it directly, but replace it with a new object containing the modification instead.</p> <p>In your case, the state object contains several nested objects. If you want to modify a "leaf" object's property, you'll also have to provide new objects for every containing object up the tree (because each of them have a property that changes in the process). Using <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign" rel="nofollow">Object.assign()</a> to create new objects, you could write:</p> <pre><code>// new "leaf" object: const newMerchandise = Object.assign({}, this.state.info.merchandise, {label: "New Label"}); // new "parent" object: const newInfo = Object.assign({}, this.state.info, {merchandise: newMerchandise}); // new state ("parent") object: const newState = Object.assign({}, this.state, {info: newInfo}); // eventually: this.setState(newState); </code></pre> <p>By the way, you'll notice that it's easier to handle the state object when its structure tends to be "flat" rather than "deeply nested".</p> |
5,683,349 | 0 | <p>DSCS have a better story (generally) than centralized systems for offline or slow networks. They tend to be faster, which is really noticable for developers (using TDD) who do lots of check-ins.</p> <p>Centralized systems are somewhat easier to grasp initially and might be a better choice for less experienced developers. DVCSes allow you to create lots of mini-branches and isolate new features while still doing red-gree-refactor checkin on green style of coding. Again this is very powerful but only attractive to fairly savvy development teams.</p> <p>Having a single central repository for support for exclusive locks makes sense if you deal with files that are not mergable like digital assets and non-text documents (PDFs and Word etc) as it prevents you getting yourself into a mess and manually merging.</p> <p>I don't think the number of developers or codebase size plays into it that much, both systems have been show to support large source trees and numbers of committers. However for large code bases and projects DVCS gives a lot of flexibility in quickly creating decentralized remote branches. You can do this with centralized systems but you need to be more deliberate about it which is both good and bad.</p> <p>In short there are some technical aspects to consider but you should also think about the maturity of your team and their current process around SCCS.</p> |

16,046,353 | 0 | <p>Well I think that an answer for your question exists somewhere in <a href="http://technet.microsoft.com/en-us/library/cc754361%28v=ws.10%29.aspx" rel="nofollow">Microsoft documentation</a>.</p> <p>Active-Directory is a bit more more than a common LDAP Directory like OpenLDAP or Oracle Directory Server Enterprise Edition (formerly SUN Directory Server Enterprise Edition). It's a "<strong>System</strong> Directory". The main difference with a simple Directory is that it's built in with a Microsoft specific "Schema" and a security infrastructure with "Kerberos". So installing AD is the same as promoting a server in a "Domain controler". In other words you can use the AD for your own usage, but his first usage is for the "System" (Domain) security.</p> <p>ADLDS is the most recent name for an old product called ADAM (Active Directory Application Mode). As you can guess, this Directory can be created just for the usage of your own application, you can build the Schema you want, you can install it on a Worksation or a server, it exists version that you can redistribute with your own application.</p> |

Note that no one in their right minds would actually do this:</p> <pre><code>#include <stdio.h> int main() { int x = 1; size_t sz = sizeof(x++); printf("%d\n", x); return 0; } </code></pre> <p>This prints <code>1</code>, not <code>2</code>, because <code>x</code> never gets incremented.</p> <p>For some <em>real</em> fun/confusion with <code>sizeof</code>:</p> <pre><code>#include <stdio.h> int main(void) { char a[] = "Hello"; size_t s1 = sizeof a; size_t s2 = sizeof ("Hi", a); printf("%zu %zu\n", s1, s2); return 0; } </code></pre> <p>(The confusion is only if one is confused about arrays, pointers, and operators.)</p> |

4,054,833 | 0 | <p>Create an imaginary grid at whatever resolution is suitable for your problem: As coarse grained as possible for good performance but fine-grained enough to find (desirable) gaps between obstacles. Your grid might relate to a quadtree with your obstacle objects as well.</p> <p>Execute A* over the grid. The grid may even be pre-populated with useful information like proximity to static obstacles. Once you have a path along the grid squares, post-process that path into a sequence of waypoints wherever there's an inflection in the path. Then travel along the lines between the waypoints.</p> <p>By the way, you do not need the actual distance (c.f. your mention of Pythagorean theorem): A* works fine with an <em>estimate</em> of the distance. Manhattan distance is a popular choice: <code>|dx| + |dy|</code>. If your grid game allows diagonal movement (or the grid is "fake"), simply <code>max(|dx|, |dy|)</code> is probably sufficient.</p> |

If you want to support <code>/bin/sh</code> or older releases of bash, consider <code>status=$(printf '%s\n' "$status" | tr '[:upper:]' '[:lower:]')</code> instead, or just remove this line if the output of <code>gsettings get</code> is always lowercase anyhow.</li> <li>The comparison <code>[[ $status = true ]]</code> relies on the bash extension <code>[[ ]]</code> (also available in other modern ksh-derived shells) to avoid the need for quoting. If you wanted it to work with <code>#!/bin/sh</code>, you'd use <code>[ "$status" = true ]</code> instead. (Note that <code>==</code> is allowable inside <code>[[ ]]</code>, but is <strong>not</strong> allowable inside of <code>[ ]</code> on pure POSIX shells; this is why it's best not to be in the habit of using it).</li> </ul> <p>Note that whitespace is important in bash! <code>foo = bar</code>, <code>foo= bar</code> and <code>foo=bar</code> are completely different statements, and all three of them do different things from the other two.

3,798,094 | 0 | How can avoid people using my code for evil? <p>I'm not sure if this is quite the right place, but it seems like a decent place to ask.</p> <p>My current job involves manual analysis of large data sets (at several levels, each more refined and done by increasingly experienced analysts). About a year ago, I started developing some utilities to track analyst performance by comparing results at earlier levels to final levels. At first, this worked quite well - we used it in-shop as a simple indicator to help focus training efforts and do a better job overall.</p> <p>Recently though, the results have been taken out of context and used in a way I never intended. It seems management (one person in particular) has started using the results of these tools to directly affect EPR's (enlisted performance reports - \ it's an air force thing, but I assume something similar exists in other areas) and similar paperwork. The problem isn't who is using these results, but how. I've made it clear to everyone that the results are, quite simply, error-prone.</p> <p>There are numerous unavoidable obstacles to generating this data, which I have worked to minimize with some nifty heuristics and such. Taken in the proper context, they're a useful tool. Out of context however, as they are now being used, they do more harm than good.</p> <p>The manager(s) in question are taking the results as literal indicators of whether an analyst is performing well or poorly. The results are being averaged and individual scores are being ranked as above (good) or below (bad) average. This is being done with no regard for inherent margins of error and sample bias, with no regard for any sort of proper interpretation. I know of at least one person whose performance rating was marked down for an 'accuracy percentage' less than one percentage point below average (when the typical margin of error from the calculation method alone is around two to three percent).</p> <p>I'm in the process of writing a formal report on the errors present in the system ("Beginner's Guide to Meaningful Statistical Analysis" included), but all signs point to this having no effect.</p> <p>Short of deliberately breaking the tools (a route I'd prefer avoiding but am strongly considering under the circumstances), I'm wondering if anyone here has effectively dealt with similar situations before? Any insight into how to approach this would be greatly appreciated.</p> <p>Update: Thanks for the responses - plenty of good ideas all around.</p> <p>If anyone is curious, I'm moving in the direction of 'refine, educate, and take control of interpretation'. I've started rebuilding my tools to try and negate or track error better and automatically generate any numbers and graphs they could want, with included documentation throughout (while hiding away as obscure references the raw data they currently seem so eager to import to the 'magical' excel sheets).</p> <p>In particular, I'm hopeful that visual representations of error and properly created ranking systems (taking into account error, standard deviations, etc.) will help the situation.</p> |

This is not helpful for our case example, so instead we could use something like this:</p> <pre><code>>>> '{:.20f}'.format(a) '-0.00000000000000007186' </code></pre> |
40,887,193 | 0 | D3.js zoom is not working with mousewheel in safari <p>I'm using D3 v4 to achieve the zoom functionality and everything works perfectly on FireFox, Chrome browsers.</p> <p>Quite different behavior with <code>Safari</code> browser (my version is <code>Version 10.0.1 (12602.2.14.0.7)</code>). Wheel zoom works for <code>g</code> element and doesn't work for <code>svg</code> element. Note: that <code>dbClick</code> zoom works for <code>svg</code> element.</p> <p>I've created simple <a href="https://jsfiddle.net/vbabenko/zq0v1rta/1/" rel="nofollow noreferrer">fiddle example</a> where tried to reproduce the issue. If you try wheel zoom over <code>red rect</code> - it will work, outside of <code>rect</code> - not work, but works for other browsers.</p> <p>I was looking for official examples like <a href="https://bl.ocks.org/mbostock/db6b4335bf1662b413e7968910104f0f" rel="nofollow noreferrer">https://bl.ocks.org/mbostock/db6b4335bf1662b413e7968910104f0f</a> where everything works and I could not find a problem with my example...</p> <p>Here is a zones where zoom works (madness is that left and top zone in the svg has working zoom): <a href="https://i.stack.imgur.com/XNZdv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XNZdv.png" alt="wheel_zoom_working_zones"></a></p> |
