COMMON STOCKS AND UNCOMMON PROFITS by Phillip Fisher (Growth Investing)

Here is the link.

COMMON STOCKS AND UNCOMMON PROFITS by Phillip Fisher (Growth Investing) Philip Fisher is known as the father of growth investing. His growth investing strategy is based on a 15 point checklist which he refers to as his scuttlebutt approach. He is a long term investor and is not afraid to invest in a stock if it is priced above its intrinsic value, anticipating that the growth will increase many fold in the future. Fisher is a hugely influential investor, even Warren Buffet recommends Fishers style. His son Ken Fisher is also well known, but more as a value investor than a pure growth investor. Claimed to be one of the best investing books of all time.

How spending $6 could keep thieves away from your catalytic converter

“You Etch It. We Catch It” Surrey RCMP and partners launch new crime prevention strategy taking aim at catalytic converter theft

 2023-04-01 11:00 PDT

Surrey RCMP and community partners are launching a new crime prevention initiative during Auto Theft Enforcement Month aimed at decreasing catalytic converter theft and making it harder for thieves to avoid detection.

The You Etch It. We Catch It campaign will allow people to have their vehicle identification number (or VIN) etched onto their catalytic converter free of charge when they are having other servicing completed at participating businesses throughout the city.

This distinctive marking will make it easier to identify a catalytic converter as stolen and connect it to a victim, while also acting as a potential deterrent for thieves.

The initiative is the result of a collaboration involving the Surrey RCMP South Community Response Unit, Property Crime Target Team, ICBC, and the City of Surrey in response to a rise in catalytic converter theft.

Last year, our crime analysts determined catalytic converter thefts made up 45% of theft from auto reports in the city, with 2143 catalytic converters stolen in 2022 alone, says Cpl. Vanessa Munn, Surrey RCMP Media Relations Officer. This new initiative will provide an extra layer of reassurance for vehicle owners, and an additional tool for police, as we target prolific catalytic converter thieves and make it more difficult for them to operate.

ICBC has seen the number of claims and claim costs for catalytic converter thefts rise in recent years, says Karen Klein of ICBC. We welcome this new strategy in partnership with the Surrey RCMP as a means of driving down this type of crime and reducing the risk to vehicle owners.

Look for local business partners displaying You Etch It. We Catch It posters. Participating business will provide window decals to anyone who has their Catalytic Converter etched, to deter thieves from targeting that vehicle.

Businesses wishing to participate can contact Surrey RCMP at Surrey_business_engagement@rcmp-grc.gc.ca. Participants will be provided with advertisement materials to highlight their participation in this initiative.

Theft of a catalytic converter can take less than a minute. The devices are attractive to thieves due to their valuable precious metal content, and SUV’s and trucks are often targeted due to being higher off the ground, which provides easier access for criminals.

There are other steps vehicle owners can take to mitigate the risk of catalytic converter theft, including parking in a secure garage or close to a wall or barrier, adjusting your vehicle security system to respond to vibrations such as those produced by a saw, and installing an anti-theft device such as a catalytic converter lock.

If you witness a crime in progress such as a catalytic converter theft, call 911. To report a crime that is not in progress, call our non-emergency line at 604-599-0502. You can also report certain types of crimes online at www.surreyrcmp.ca/report.

You can find out more about the You Etch It. We Catch It program at these upcoming community events:

How to Prevent Kia Sportage Catalytic Converter Theft

 If there’s no NICB etching event near you, you can get it done at your local muffler shop. Or, if you want to try a similar DIY method, get a can of automotive exhaust system spray paint. You can use it to tag your catalytic converter, making it easily identifiable and less likely to be stolen. 

Meta paid VR developers salaries of up to $1 million. Facebook’s owner is now in financial trouble.

 

For years, Meta has pushed a rosy vision about the future of human communication in which people — represented by a diverse slate of avatars — work, play and shop together in immersive digital worlds accessible through virtual reality-powered devices.

What the company hasn’t said is that it’s paying exorbitant salaries to programmers to turn that vision into a reality. Programmers capable of building out virtual reality-powered games, apps and technology can earn total compensation from $600,000 to packages approaching $1 million, according to people familiar with the matter who spoke on the condition of anonymity to discuss internal matters.

The Facebook parent company is “paying significantly more than a lot of gaming companies,” said Andiamo chief executive Patrick McAdams, whose firm recruits tech talent for big and small companies. “It’s not an exaggeration to say that their total compensation is double or more than double of what you’ll get at a large gaming company.”


Of the virtual reality developers who were offered jobs at Meta over the last nine months, those that were in the top 90th percentile in terms of total compensation earned an average of $538,800, according to data from Levels.fyi, which tracks salaries in the tech industry. That figure was higher than the $495,400 Apple paid its highest-earning developers and the $440,000 Google paid its VR programmers, the data showed. Apple, Google and Meta all paid comparable base salaries, according to the data.

勤换床单,有利于你的人生健康

 最近,一篇名为《床单10天不换,皮肤很受伤!》的文章,在网络上炸开了,被各大媒体转发!文章称,据美国《红书》杂志介绍,不换床单会给皮肤带来健康隐患,应7-10天清洗更换。

  那么,十天不换床单真的会伤害皮肤吗?事实到底是怎样的呢?今天,就跟随福建医科大学附一闽南医院皮肤科医师林小清了解一下。

  人的一生大约有三分之一以上的时间是在床上度过的(排除工作狂、不睡觉的),一个人每天按8小时睡觉时间,跟床接触的时间远远大于跟其他东西接触时间。人每天都是在不断新陈代谢,人体的皮肤也是这样,都会有新老更替。在床上睡觉时,人体的死皮(鳞屑)、油脂、汗液、毛发等都会掉落在床上,包括有些人在睡觉时会涂一些保湿霜等,都有可能粘在床垫上。而有些人会在床上吃东西,不小心都会把食物渣渣及饮料等掉在床上。

  这些东西可以是尘螨、真菌、细菌等良好的培养基,再加上适合的温度、潮湿等,这些“小伙伴”就会疯狂生长。研究表明,平均每张床上被褥螨虫和尘埃螨虫至少有1500万只。

  “没有看到,不代表不存在。而这些东西长期存在,对皮肤来讲都是一种伤害。如果长时间不换床单,有可能会引发各种各样的皮肤疾病。”林小清说道。

  而长期不换床单则会引起湿疹或接触性皮炎、体股癣、手足癣、丘疹性荨麻疹等皮肤疾病。林小清建议每天清扫一次床铺,7-14天左右换洗一次床单。及时清洗床单及被套等,可以清除床上的皮屑等,可以破坏其营养物质,破坏其适应的生存环境。清洗时可以直接或间接杀灭螨虫、真菌、臭虫等,从而减少我们皮肤的患病率,减少伤害。如果没有办法做到这么勤快清洗,也需要经常把门窗打开通风,让阳光照射房间,也是很有用的。

How to Install WordPress on Docker (Windows, macOS, and Linux)

Here is the article.

Nginx | an article from the WordPress Codex

Here is the article. 

While the LAMP stack (Linux + Apache + MySQL + PHP) is very popular for powering WordPress, it is also possible to use Nginx. WordPress supports Nginx, and some large WordPress sites, such as WordPress.com, are powered by Nginx.

When talking about Nginx, it is important to know that there are multiple ways to implement Nginx. It can be setup as a reverse-proxy in front of Apache, which is a very powerful setup that allows you to use all of the features and power of Apache, while benefiting from the speed of Nginx. Most websites that report using Nginx as the server (based on stats gathered from HTTP response headers), are actually Apache running with Nginx as the reverse proxy. (The HTTP response headers showing “Nginx” are being reported by the reverse-proxy, not the server itself.)

This guide is referring to a standalone Nginx setup, where it is used as the primary server instead of Apache. It should be noted that Nginx is not a completely interchangeable substitute for Apache. There are a few key differences affecting WordPress implementation that you need to be aware of before you proceed:

  • With Nginx there is no directory-level configuration file like Apache’s .htaccess or IIS’s web.config files. All configuration has to be done at the server level by an administrator, and WordPress cannot modify the configuration, like it can with Apache or IIS.
  • Pretty Permalinks functionality is slightly different when running Nginx.
  • Since Nginx does not have .htaccess-type capability and WordPress cannot automatically modify the server configuration for you, it cannot generate the rewrite rules for you.
  • Without modifications to your install, “index.php” will be added to your Permalinks. (There are ways to mitigate this with plugins (see below) and/or adding custom code to your child theme’s functions.php.)
  • However, if you do want to have some (limited) .htaccess capability, it is technically possible to do add by installing the htscanner PECL extension for PHP. (However, this is not a perfect solution so be sure to test and debug thoroughly before using on a live site.)

This guide is not going to cover how to install and configure Nginx, so this assumes that you have already installed Nginx and have a basic understanding of how to work with and debug it.

Generic and Multi-Site Support

To make WordPress work with Nginx you have to configure the backend php-cgi. The options available are ‘fastcgi’ or ‘php-fpm’. Here, php-fpm is being used because it is included with PHP 5.3+, so installing it is straight forward.

The Nginx configuration has been broken up into five distinct files and is heavily commented to make each option easier to understand. The author also made a best-effort attempting to follow “best practices” for nginx configurations.

WordPress | App development | Coleman, Jason, Brian | Building web apps with WordPress

 Rolling Your Own Server

The alternative to WordPress-specific managed hosting is to roll your own server, either

on dedicated hardware or in a cloud environment.

On the dedicated side, Rackspace is a popular choice, and 1and1 provides powerful

hardware at wholesale prices. On the cloud side, Amazon EC2 is very popular, and

Digital Ocean is a cost-effective alternative.

No matter which route you go, you will have to set up your own web server, install PHP

and MySQL yourself, and manage all of the DNS and other server maintenance yourself.

Depending on your needs and situation, this could be a good thing or a bad thing. If

you need a more specific configuration for your app, you have to roll your own server.

On the other hand, you’ll have to spend time or money on server administration that

might be better spent elsewhere.

It’s important to know where your limits are in terms of server administration. For

example, Jason is very experienced setting up web servers like Apache and configuring

and maintaining PHP and MySQL. On the other hand, he has little experience managing

a firewall against denial of service attacks or load balancing across multiple servers.

You’ll want to choose a hosting company and option that works to your strengths and

makes up for your weaknesses.

Rolling your own server and getting 10 times the raw performance for 1/10th the cost

of a shared hosting plan can feel pretty good. But when you find yourself up at 3 a.m.,

wasting time struggling to keep your server alive against automated hacking attempts

from foreign countries, the monthly fee of the managed options may not seem so steep.

怎么判断床上有螨虫及床上除螨虫最简单最快方法

2020-09-23 · 市场营销

判断螨虫的方法:如果床上存在一定量的螨虫,那么首先受害的是与床亲密接触的皮肤。比如螨虫会爬上脸部、四肢以及背部等部位,引起红疹、皮肤粗糙、粉刺、水疱、黑头、酒槽鼻、毛孔粗大等症状,当螨虫足够多的时候,皮肤会发痒。

对于很多人来说,螨虫其实是一种过敏原,因此常引起皮肤过敏、荨麻疹、哮喘和过敏性鼻炎等。如果有这些情况,就说嘛床上有螨虫。


除螨虫方法:定期清洗床上用品、回家后更换衣物、室内多通风、黑塑料袋除螨虫、清洗床单时加些花露水。

1、定期清洗床上用品,建议家里备两套床上用品,每月个换洗一次。洗干净后,放在阳光下晒,这些不可爱的螨虫最怕就是阳光了。

2、回家后更换衣物,在外面工作或者玩了一天,衣服肯定是有细菌和灰尘的。如果我们不换衣物就躺在床上,会污染到床被。最好就是,我们回到家里,马上就换上舒适的家居服,然后把外出的衣服挂起来。

3、室内多通风,螨虫偏爱潮湿的环境,我们尽可能减低房间内多余的湿气。比如像小编在南方居住,潮湿梅雨天气不时会来打搅,房间湿度实在过大。这时建议大家,可以关闭房门,然后用辅助以除湿器。

螨虫是一种肉眼看不见、却无处不在的小虫子,一般来说螨虫有50000多种,其中尘螨最为常见,广泛分布于居室的阴暗角落、地毯、床垫、枕头、沙发、空调等各处,床褥上尤为多,对于“床上除螨虫的最有效方法”我也整理出了一点经验:

1、物品及时消毒、进行暴晒

室内的东西一般“洗、烫、晒”三种方式都可以去除螨虫,因为螨虫是比较怕热的,当温度在55℃以上的时候,10分钟就能杀死螨虫,60℃以上的话三分钟就可以杀死。

所以把家里的东西用热水烫一烫进行杀菌消毒、或是打开窗帘暴晒等方法都可以去除螨虫。

蒸汽技术 | Karcher

你睡觉时有没有过这样的体验?总感觉身上这里痒一下,那里痒一下,就像有小虫子在身上爬,睡不踏实,仔细找却什么也没发现。脸上和身上经常莫名其妙冒痘痘,长小疙瘩。怎么就过敏了呢?其实罪魁祸首就是床上的:螨虫,我们平时也经常听到除螨除尘的方法,那些真的有效吗? 

其实,Karcher德国卡赫在研发蒸汽技术之时,就已经考虑到家庭织物卫生清洁的需要。在国外,90%的家庭清洁衣物的过程都包含了高温杀菌这一过程。然而在国内,却很少有家庭会有高温杀菌的习惯。

Karcher德国卡赫蒸汽机就完美解决了这个问题,它不仅可以熨烫衣物和家庭织物,还可以对地毯、沙发等螨虫聚集的表面进行深入清洁和除螨,可谓绝妙的清洁措施,在杀菌杀螨去味的同时,还能杀灭99.99%的细菌。


Karcher德国卡赫产品通过国际权威机构认证,卡赫蒸汽机产生的高温蒸汽分子可深入缝隙,99.99%杀除包括大肠杆菌、金黄色葡萄球菌、白色念珠菌等家庭常见菌种,除螨率高达99.99%。整个过程无需化学剂,只用清水,绿色环保,有效减少过敏原,让过敏和易敏感人群受益。


螨虫危机,已经成为现代生活不能忽视的问题之一。尽早养成除螨习惯,才是送给全家人最好的健康礼物,而Karcher德国卡赫不仅是日常除螨智慧之选,更是家庭深度清洁、杀菌消毒的得力助手。

电熨斗

 电熨斗能烫死衣服上的臭虫卵,臭虫不耐高温,可用蒸汽电熨斗将虫卵和成虫全部烫死,对衣服的缝隙要反复多次熨烫效果会更好。

你睡觉的床如何成了细菌、尘螨的温床

 没有什么比躺在床上裹着毯子,把头埋在枕头里更舒服了。但在你安心享受这种舒适之前,需要了解到你的床与细菌培养皿其实没有区别。由于混合了汗水、唾液、头皮屑、死皮细胞甚至食物颗粒,你的床也成为大量细菌、真菌、病毒甚至小虫子等生长的最佳环境。

  例如,一些研究发现,医院的床单上经常可以发现葡萄球菌。这些细菌通常是无害的,但当它们通过伤口进入人体后,会导致严重的疾病,且一些特定种类的葡萄球菌会会造成更严重的伤害。以金黄色葡萄球菌(Staphylococcus aureus)为例,它具有很强的传染性,能导致皮肤感染、肺炎和痤疮等。一些研究还发现,其中一些金黄色葡萄球菌菌株对抗生素具有耐药性。

  研究显示,大肠杆菌和其他一些革兰氏阴性菌在医院病床上也很常见。革兰氏阴性菌会引起严重的健康问题,因为它们对抗生素具有高度耐药性。当它们进入人体后,会导致严重的感染,如尿道感染、肺炎、腹泻、脑膜炎和败血症。

  一些大肠杆菌菌株也具有很强的传染性,并可能导致尿路感染、旅行者腹泻和肺炎。这就是在上完厕所后需要正确洗手的重要原因,因为这可以防止这种细菌传播到家里的其他地方。

  当然,医院与我们家里的环境很不相同。但这并不意味着这些细菌不可能出现在我们睡觉的床上。事实上,大约1/3的人携带有金黄色葡萄球菌,能四处散布这种细菌,这也意味着葡萄球菌转移到家里的床上会很容易。

  当你躺在床上睡觉时,每天会脱落大约5亿个皮肤细胞。这些皮肤细胞可能会吸引以它们为食的微小的尘螨。而这些螨虫和它们在床上留下的粪便会引发人体出现过敏和哮喘等症状。臭虫也会带来危险。尽管这些小虫子(约5 毫米长)尚未被证明会传播疾病,但它们叮咬人体,产生发痒的红色咬痕,同时还会对人的心理健康产生影响,导致如焦虑、失眠或过敏等症状。臭虫可以通过一些柔软物体的表面(例如衣服或背包)或其他家庭成员进入家中。 在高温(约55°C)下清洗和烘干床单可以杀死尘螨,但对付臭虫可能需要专业的清理方式。

  当你使用那些不干净的家居用品(例如衣服、毛巾、马桶或浴缸、厨房表面,甚至宠物),还有可能将细菌带到床上。很多种细菌寄生在浴室和厨房的毛巾中,包括金黄色葡萄球菌和大肠杆菌。洗涤不当也会使得细菌传播到其他物品上,包括我们的床单。甚至像淋病这样的疾病也可以通过受污染的毛巾或床上用品传播。      

  不同的微生物会在不同织物上存活的时间不同。例如,金黄色葡萄球菌在棉布上可存活一周,在毛巾布上可存活两周。真菌(如白色念珠菌,可引起口疮、尿路感染和生殖器酵母菌感染)可以在纤维织物上存活一个月。流感病毒也可以在织物和纸巾上存活8-12小时。一些其他类型的病毒,例如牛痘病毒,可以在羊毛和棉花上存活长达14周。为了让细菌不会发展成真正的健康威胁,定期和正确地清洗床单是十分关键的。但是,你应该多久更换一次床单呢?

虽然我们不可能每天都清洗床单,但一件每天可以做的事是早上晾晒床单。当我们睡觉时,床单会吸收人体排出的汗液。因此,我们可以将被子折叠让床单可以充分接触空气,这样床单和床垫就不会成为细菌和螨虫的滋生地。由于积攒了多年的皮屑、食物颗粒和真菌,床垫也是细菌等微生物的一大来源。床垫很难清洗,但我们可清洗的床单和被子,并且每一到两周清洗一次,这可以帮助减少生活在床垫上的微生物的数量。

每月用吸尘器清扫床垫和床底板也有助于去除过敏原和灰尘。经常翻动你的床垫也会有一些帮助。如果床垫已经使用超过十年,最好换一个新的。清洗床上用品的频率最好是每周一次(如果可能的话,可以更频繁地清洗),尤其是当你长时间卧床、裸睡或晚上会大量出汗时。同时,也建议每两到三天更换一次枕套。为了有效地杀死细菌,所有的床上用品都应在较高的温度(约40-60°C)下洗涤,并确保在使用完全干燥的床单。

10天不洗床单,会发生什么

 这些东西可以是尘螨、真菌、细菌等良好的培养基,再加上适合的温度、潮湿等,这些“小伙伴”就会疯狂生长。据相关文献报道,平均每张床上被褥螨虫和尘埃螨虫至少有1500万只。

如何科学有效地清洗床单?

螨虫、真菌等在高温(大于60℃)、低温(小于-20℃)、干燥等环境下是不容易生存的,所以要除螨等需要做到以下几点:高温、低温、干燥、通风。

建议用55-65摄氏度的热水烫洗床单,再加热烘干或在阳光下暴晒。这样可以除去附着在床上用品表面的微小杂物、灰尘以及汗液等,还能有效帮助杀死细菌和螨虫。

对于白色床单还可以加一点漂白剂和消毒剂,漂白后的产物是氧气和水,维持水的中性特质,但其杀菌、去污能力和氯系漂白剂相当。但是要彻底用清水漂洗干净,否则,漂白剂、消毒剂作为一种化学剂,同样有刺激危害。可以选择最温和的活性氧漂白剂。

如果在北方都是零下几度甚至十几度的时候,没有足够的阳光照射,可以放在外面冰雪天气下,通过低温来杀螨虫及相关病原菌。

在南方,冬天没有足够的阳光也没有那么冷的冰雪天气,那应该怎么处理呢?建议通过正常的清洗之后,可以考虑用电熨斗熨烫一下床单,也是可以有效杀灭的。

家里还有哪些东西容易长螨?

我们的睡衣、毛毯、布沙发、毛绒绒玩具等也是螨虫喜欢生长的地方,都需要定期清洗。

尽量保持室内通风、干燥,也可以有效杀螨、杀菌!
