It seems QuickFIX has not log rotation feature.
Is it possible to do it somehow?
This post shows the rotation might have been released longtime ago. There mayn't be any config change to be made, maybe you need to implement it yourself as described in the post.
Here it explains that it isn't possible to rotate without shutting down your engine. Your engine would have the old hook to the logfile and when it sees that the log file doesn't exist, probably would crash. In the same post it explains that divide your multiple seesions for each day, 7 logs for 7 dys in the week. Should be a plausible method to do it, when you shouldn't be restarting your engine in the middle of a day.

I have an NFC tag that has integrated environmental sensors inside (MLX90129 to be exact). I would like to make an iPhone app that can read the realtime data from the tag multiple times per second and graph them. I'm not looking for background tag reading, and you can assume that the app will be open and the phone is near the tag at all times.
From what I can see on Apple documentation and other sources, the Swift support for NFC tags is mostly built for single session interrogation. Has anyone succeeded in getting continuous and repeated NFC tag reading for this type of purpose?
As you pointed out: "to make continuous and repeated NFC readings" it's not the intended functionality.
While I think that you can sort this out, there's another thing that could be a headache... to make multiple readings per second it's directly confronted to the current implementation of NFC tag reading in iOS.
Every time you start a reading, it shows the native window which informs the user that you are making a NFC Reading. A part of this process is the interaction of the user, and is exactly that part the one that imposes a time constraint. Even if the interaction with the user is not needed, there is an animation, and that animation has its lifecycle's events (start reading, reading, OK, KO, close...).
Afaik you can't bypass that animation which definitely could represent a couple seconds in the best case.
With that said, you should have a few things in mind, if you still want to try:
NFCTagReaderSession can only have one active reading at a time, and when that reading ends (OK/KO), it should be invalidated. So if you want to make another reading, you'll need to create and configure a new instance.
I'm using SpringMVC, Quartz 2.2.1 with Mysql 5.6.15.
I have a scheduled task that use some web resources. Now the resources are not available, so I need to ignore the task temporarily, waiting for them to be back.
I think changing the code is too much for such a minor issue. While knowing it's not recommended, I guess altering the Quartz Mysql database is the best way to go.
I find this answer suggesting :
UPDATE QRTZ_TRIGGERS SET TRIGGER_STATE = "PAUSED"
the answer is 7 years ago and the replyer not responding, I tried to find the doc saying so, but no luck. I wanna know :
Is this the right way to do, without any side-effect?
What does QRTZ_PAUSED_TRIGGER_GRPS table for? Do I need to alter it?
I'm getting pretty bad results with Area Learning, the localization takes very long and I have no idea what's happening. Did I map the area enough? Is there enough landmarks? Is the ADF alright? No clue.
Is there any way to provide a visual feedback while doing the actual motion tracking and area learning? I keep seeing it in Google videos but didn't find any way of doing it in the Unity SDK.
I would like something like this in my video overlay: https://youtu.be/NTZZCtmR3OY?t=10m57s
Btw my results in Unity are FAR worse than this demo, sometimes it takes minutes for the device to localize and only at a certain spot in the room, the next minute the very same spot doesn't work again. Quite frustrating. No idea what app the presenter uses, for instance, my ADF Inspector reliably crashes every time I try to load any ADF. (Using Wasat and recently I've deleted and re-installed everything.)
It is not supposed to be so. It should not be that bad, under the normal day light condition. If it is a small area, should be able to localize using ADF within 3-5 seconds. The video showed the usual case -- always like this.
If your kernel is up to date, and you are using the correct development kit. I would recommend you to reach the tango team customer service directly.

Perhaps it is caused by your device defective. If so, ask for an exchange would solve the problem.
We have a main ruleflow which calls 8 more rule flows (Rule1.rf to Rule8.rf) through an AND splitter. One of the rule flows - say Rules4.rf - is fired sometimes and not fired sometimes.
This is for an online application and we use jBoss. When the server is started, everything works fine. After many hours, for some requests, Rules4.rf is not fired at all and for others, its fired properly.
We even posted the same request again and again and the issue happens some times only. There is no difference in the logs between the success & failure requests, except for the logs from the Rules4.rf which missing in failued requests.
We are using drools 5.1 and java 6.
Please help me. This is creating a very big issue.
It is very difficult to figure out what might be going on without being able to look at the actual code and log. Could you by any chance create a JIRA and attach the process and if possible (a part of) an audit log that shows the issue?

My page load times have been wildly fluctuating, and sometimes it takes so long to serve a page that I get a server timed out error, even during relatively quiet times of day for my site.
I have been using pingdom to check page load times and to try and find where the problem lies.
It seems when a page loads normally (in approx 6 seconds), there is a 1.63 second 'Wait' Time for the main html file, before it starts receiving the file.
You can see this here:
http://tools.pingdom.com/fpt/#!/GEoqJlVdZ/http://www.bluedogposters.com.au/shopdisplayproducts.asp?id=11&cat=Movies
But 2 minutes later, when the same page is taking 17 seconds to load, there is an 11.7 second Wait Time before starting to receive this same html file.
You can see an example here:
http://tools.pingdom.com/fpt/#!/he2L5Jhgz/http://www.bluedogposters.com.au/shopdisplayproducts.asp?id=11&cat=Movies
Do you know what can cause this difference in the Wait times because it seems this is the reason my site has been so slow recently.
Accoring to the Waterfall chart, there is nothing else happening, so why the Wait?
Is it more likely to be a code or server issue?
I found some useful info here How to reduce server "Wait" time?
Any advice is much appreciated.
You need a tool that can dig into the backend performance, something like New Relic might help - they do a free month trial.
There's obviously some variation in performance going on but whether it's related to load or other factors is really hard to discern without digging deeply.
You should try new relic anyway, it will still give you a good answer even on an ASP classic site. I have used it on windows servers before to figure out why an app was running slow.
