@mtrainier2020 @leeoxi 我也是UBNT的设备,Frigate似乎检测功能更强大…你觉得默认的ubnt软件提供的检测功能够用吗?不过我是家用,想用HomeAssistant做一系列smart home联动

嗯嗯。想明白这个是这么配置的了。首先库房里面有3个hub(8口 poe switch,然后接出8根线,接8路poe摄像头,然后poe switch上通过光纤网口转接器,通过光纤接入server room),server room 中再通过光纤 网口转换器接入 路由器、接入互联网。
外面的poe hub 接电,解决poe camera的电源问题。通过光纤接入server room,接入互联网,解决数据问题。
我可以营业给超大库房建监控网络了😆。

@mtrainier2020 这个是光口。poe是电口。poe上行光口的话,可以接这个。接口类型sc或lc

@mtrainier2020 @leeoxi 雷总…请问你用下来感觉Macmini+Frigate效果怎么样?我有8个4K ubnt camera,主要比较担心inference的速度和软件支持的问题。现在在看Minisforum的机器,也有考虑Frigate推荐的NUC+Coral的solution

@mtrainier2020 最近看到一个网站,列举了很多统计上强相关但是毫无关系的数据:tylervigen.com/spurious-corre…

给你推荐一本书。how to lie with statistics。
如果你无脑相信你看到数据,那么你活该被骗。
我不知道你是不是生活在美国,也不知道你是不是考过GRE,学没有学过 argument。
举个例子:
华州在2012年通过了大麻合法化的答案,然后犯罪率大幅降低。
这个claim的问题在哪里?是不是正确的?
怎lie的?
在合法化前,有很多人吸食大麻,所以抓到了都算犯罪。 比如非大麻类犯罪案例10K起,吸食大麻3K起。总共crime 13K
在合法化后,吸食大麻无罪了。但是非大麻类案件上升到了11K件。 因为大麻无罪了。所以是0。
总crime是11K件。
是不是形势一片大好啊!

@SparkMailApp In my testing, new Spark uses 3 times more memory than the old version. Please don’t try to downplay this as many developers are using your product and they know exactly how to calculate the resources :) Thanks @_iangray for the screenshot!

@WangWillDC Hi Will! Please note that Spark Desktop doesn't take more resources than the previous one. In addition, we won't remove the Original Spark from Mac AppStore for at least a year and you can use it simultaneously

@SparkMailApp Now I am on another hunt of good email app for Mac…sigh…

@SparkMailApp The moment I see Spark 3 supports Windows, I instantly said “Crap!”. I am deeply disappointed that Spark 3 Desktop becomes a “Web App”. I simply don’t need another browser (Electron) running on my already slow enough Mac.

@NotionHQ @ArcInternet @browsercompany seems like a great feature to add to Arc. The could be useful if user just wanna preview a link

@joshbloch So sorry to hear this…As your student in CMU, I told several other CMU students about this and we all hope you feel well soon! We missed you being so energetic when you were giving lecture! Hope that Josh comes back better and stronger!

@dteare Great Feature! I am not sure if this is the right place for feature requests, but could 1Password add an option to specify which field(s) in an item to share? E.g my router item contains password for admin, which I don’t wanna share. I only want to share the wifi password

Love how this turned out! We’ve been researching external sharing for years now and we landed in a really nice place.

Psst! We’re announcing something new today. Take a sneak peek: bit.ly/3v1FAuu

@Kurz_Gesagt I hope someone could come up with this, just like how Luis vin Ahn digitalized old New York Times using CAPTCHA.

@Kurz_Gesagt If only we could put all these computing power toward some kind of bio/chem experiment. If there’s a bio/chem experiment that awards me with some kind of coin for a unit of computation power I contribute, I would ditch bitcoin instantly.

@SparkMailApp I’ve been wondering what obstacle did you guys meet when trying to support M1, given it’s taking such a long time. Do you have a tech blog recording this process?

@dpovey1 Just saying, the #Strike4BlackLives event outright excluding Asians in their “minority list”

@daverothery You could think of it as CCTV camera if you will, and they weren't calibrated for color indeed. The reason they are not using a science camera is because lander was going to hibernate in a short time due to high temp on moon, so they decide not to activate science camera then
English

@daverothery Hi @daverothery, so someone from CNSA read my translated version of your article and contacted me to clarify a few things. First, the cameras used to take the red photos are not for navigation purposes. They are used to monitor whether rover is successfully released from lander
