256,214 | 0 | <p>SNMP has quite a significant CPU hit on the devices in question compared to telnet; I'd recommend telnet wherever possible. (As stated in a previous answer, the IOS XR XML API would be nice, but as far as I know IOS XR is only deployed on high-end carrier grade routers).</p> <p>In terms of existing configuration management systems, two commercial players are HP Opsware, and EMC Voyence. Both will probably do what you need. I'm not aware of many open source solutions that actually support deploying changes. (<a href="http://www.shrubbery.net/rancid/" rel="nofollow noreferrer">RANCID</a>, for example, only does configuration monitoring, not pre-staging and deploying config changes).</p> <p>If you are going to roll your own solution, one thing I would recommend is sitting down with your network admin and coming up with a best-practice deployment model for the service he's providing (e.g. standardised ACL, QoS queue, and VLAN names; similar entries in ACLs that have the same function for different customers, etc.). Ensure that all the existing deployed config complies with this BP before you start your design, it will make the problem much more manageable. Best of luck.</p> |

33,026,996 | 0 | IAB, onActivityResult() and the strange message "startActivity called from non-Activity context" <p>I am using OpenIAB to support in app purchasing in my app (OpenIAB uses google code to implement IAP for Google Play Store). The problem is that, sometimes, when i call launchPurchaseFlow(), the method onActivityResult() of my FragmentActivity is not called. Checking the logs, i have found that when this happens there is always the following msg:</p> <blockquote> <p>W/ActivityManager( 319): startActivity called from non-Activity context: forcing Intent.FLAG_ACTIVITY_NEW_TASK for: Intent { cmp=com.android.vending/com.google.android.finsky.billing.lightpurchase.IabV3Activity (has extras) }</p> </blockquote> <p>When this happens, i have to close the app. Usually it start working again after some time (i have absolutely no clue of why is it so). I don't know why this message show up, since the context is obviously my activity (and in fact it works most of time). I have to say that the .apk installed on my device is an updated verion with respect to the apk uploaded in the beta version of the developer console and that i am using my google developer account to test IAP. This implies that i cannot make any real buy. However, this is not important, since i am testing the app. These are my questions: </p> <ol> <li>Is it true that starting an activity for result with FLAG_ACTIVITY_NEW_TASK prevents onActivityResult() to be called?</li> <li>How do you explain that message?</li> </ol> <p>Regarding the first question, i have tested with launchMode=singleTask and the behaviour is the same of launchMode=singleTop.</p> |

3,320,065 | 0 | <p>Lesson one in Joel's test should be: <em>Do you regularly critically revisit the software team quality tests?</em></p> <p>While I like Joel and the list is a good list, it's only a starting point and without proper knowledge of how to apply any part that that test tells you to apply, you won't get far by just introducing them to your team. Worse, it may do more harm than good.</p> <p>With a current client, much of that test would've failed when I started out there. Explaining the managers that quality is something measurable in less bugs, better understanding of process and better understanding of delays (!) and cheaper on a very short notice helped me introduce many of those concepts. </p> <p>It was and always has been hard to introduce any tools that cost money (do the math: a programmer may cost a company $6000 a month all in, that extra tool for $300 a year per seat that saves you 1 hour a day, somehow managers just can't calculate, they'll still consider it too expensive). It's a silly truth and in the end the company will not only loose time, but also the programmers.</p> <p>But you have to start somewhere. <strong>Don't overwhelm the team, but slowly introduce them to new concepts</strong>. Source control (a good one, do <em>not</em>, I repeat, <em>DO NOT</em> use Visual Source Safe), feature/debug tracking and quiet working conditions will get you more than halfway, are cheap or free and are easy to introduce. You can (ab)use the feature tracking system for documentation, specifications, bug tracking and planning. Together with rollback facilities of source control this will get you a large part of the x/12 score.</p> <p>Don't (yet) attempt anything that delays the process or "feels like" a lot of work <em>before any result is seen</em>. These are things like a release schedule, specifications like FD and TD and (very) expensive tools that require knowledge that you currently don't have (interpreting the output from a good memory profiler is an art on itself, for instance). Introduce new concepts slowly and you should be fine.</p> |

38,128,598 | 0 | Strange SIGPIPE in loop <p>After dealing with a very strange error in a C++ program I was writing, I decided to write the following test code, confirming my suspicion. In the original program, calling <code>send()</code> and <code>this_thread::sleep_for()</code> (with any amount of time) in a loop 16 times caused send to fail with a <code>SIGPIPE</code> signal. In this example however, it fails after 4 times. </p> <p>I have a server running on port 25565 bound to localhost. The original program was designed to communicate with this server. I'm using the same one in this test code because it doesn't terminate connections early. </p> <pre><code>int main() { struct sockaddr_in sa; memset(sa.sin_zero, 0, 8); sa.sin_family = AF_INET; inet_pton(AF_INET, "127.0.0.1", &(sa.sin_addr)); sa.sin_port = htons(25565); cout << "mark 1" << endl; int sock = socket(AF_INET, SOCK_STREAM, 0); connect(sock, (struct sockaddr *) &sa, sizeof(sa)); cout << "mark 2" << endl; for (int i = 0; i < 16; i++) { cout << "mark 3" << endl; cout << "sent " << send(sock, &i, 1, 0) << " byte" << endl; cout << "errno == " << errno << endl; cout << "i == " << i << endl; this_thread::sleep_for(chrono::milliseconds(2)); } return 0; } </code></pre> <p>Running it in GDB is how I discovered it was emitting SIGPIPE. Here is the output of that: <a href="http://pastebin.com/gXg2Y6g1" rel="nofollow">http://pastebin.com/gXg2Y6g1</a> </p> <p>In another test, I called <code>this_thread::sleep_for()</code> 16 times in a loop, THEN called <code>send()</code> once. This did NOT produce the same error. It ran without issue. </p> <p>In yet another test, I commented out the thread sleeping line, and it ran all the way through just fine. I did this in both the original program and the above test code. </p> <p>These results make me believe it's not a case of the server closing the connection, even though that's usually what SIGPIPE means (why did it run fine when there was no call to <code>this_thread::sleep_for()</code>?). </p> <p>Any ideas as to what could be causing this? I've been messing around with it for a week and have gotten no further.</p> |
40,682,585 | 0 | <p>I'd avoid it. My biggest issue with it is that sometimes you're returning a list, and sometimes you're returning an object. I'd make it work on a list <em>or</em> an object, and then have the user deal with either wrapping the object, of calling the function in a list comprehension.<br> If you really do need to have it work on both I think you're better off using:</p> <pre><code>def func(obj): if not isinstance(obj, list): obj = [obj] # continue </code></pre> <p>That way you're always returning a list.</p> |
