क्या em कर सकते हैं जो % द्वारा नहीं किया जा सकता है ?

प्रत्येक मूल्य का निर्धारण करने का एक अलग तरीका प्रदान करता है, और प्रत्येक के पास कुछ फायदे / नुकसान हैं यह विशेष रूप से विशिष्ट संपत्ति के आधार पर भिन्न होता है।

फ़ॉन्ट-साइज़िंग के लिए, इन दोनों को अलग करने के लिए बहुत कुछ है: दोनों अपने माता-पिता के फ़ॉन्ट के सापेक्ष फ़ॉन्ट आकार करेंगे, और दोनों एक ही मान (& lt; संख्या & gt;) तो समान रूप से सटीक होना चाहिए।

अन्य गुणों जैसे चौड़ाई के लिए, अंतर बहुत महत्वपूर्ण है प्रतिशत मूल्य प्रभावी रूप से विंडो आकार के अनुसार भिन्न होने की क्षमता प्रदान करते हैं। एम-आधारित मान आपको फ़ॉन्ट आकार के अनुसार आयामों को अलग करने की अनुमति देते हैं। पूर्व आउटपुट उपकरणों की एक श्रृंखला को संभालने के लिए महान है। उत्तरार्द्ध लगातार लाइन लंबाई को बनाए रखने में महान है।

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!

unix - Listing all shared memory segments used by a process on AIX5.3+ -

-
I would like to find all the shared memory segments used by a given process I am particularly interested in detecting shmid That's why I can use it in call (shmctl). On Solaris I will just read / proc / $ PID / map to find that information (field pr_shmid) The content of that file is defined by struct prmap_t in the sys / procfs format. Ax also has a / proc / $ PID / map file. Any project is a primate, but unfortunately it has been projected in pr_shmid field. Any ideas how can I get it on AIX5.3 +? I do not particularly know about AX, but I think that ipcs command is quite standard where SysV IPC is supported, so I want to get the ipcs -m command to give the appropriate code; If you can not find a better method, then there may be an option to parse its output.

tsql - Correct sql/hql query (aggregate in where clause) -

-
I want to query the query as below but the question is wrong but describes my intentions. select name, date time, data from record, date time = maximum (date time) Update: OK The description of the query intentions is not very good. My bad I want to select the latest record for each person. i like Mickey's answer and quosnoye (and upyoyed miki), but if your needs are similar to me , You should keep in mind some limitations. First and foremost, this works only when you are looking for the latest record or latest record for the same name. If you want the latest record for each person in a set (a record for each person but the latest record for each), then the above solutions are small. Second, and less importantly, if you work with a large dataset, then it can be slow for a long time. So, what's around the work? Whatever I do is to add a small field to mark the "latest" in the table. Then, when I store a record (which is done in the stored procedu...
