日本汉字

1946年,日本政府出台了一个汉字改革文件,规定了1850个常用汉字,这1850个常用汉字以外的汉字则不再使用,要么通过假名标记,要么用其它同音汉字代替。从这个汉字改革文件开始,一些常用汉字,在笔画上也进行了简化。

日本的汉字总共有2500个常用汉字,中文有3000个常用汉字,但日本汉字简化的远没有中国多,大部分仍与繁体中文相同。

日本开始了全面学习引进西方工业文明的明治维新,并创造性地使用汉字翻译西方科技的专门术语,并传到了中国,彻底改变了汉语的语言构成。
为了提高书写和阅读效率,日本简化了汉字,被称为“略字”。

C語言

C++常被工程師們調侃是C語言的升級版,但其實並非如此,C++擁有C語言沒有的「物件導向設計」,使得學習C++比起C語言會更加容易,由於物件導向帶來的方便性,且承襲C語言的優點及特性,使得C++常常用來撰寫電腦的軟體,常見的office系列軟體就是以C++撰而寫成的,C++課程除了教會初學者簡單的程式撰寫及製作,也提供進一步的編譯器和資料庫撰寫指導,若想成為軟體工程師,C++是你必備的工具,報名C++課程,和大家一同開發出熱銷又實用的軟體吧!

-------------------------
C#是採用全物件導向設計的高階語言,比起C和C++,更容易學習及撰寫,是不少初學者的首選之一,擁有跨語言卻無誇平台的特性。比起程式開發,C++的應用多於C#;但網頁設計方面,C#則大大勝出,許多的網頁及服務平台,都是以C#為基礎而開發成的,而資訊爆炸的時代到來,許多商家及公司行號都需要網站的架設,使得網頁工程師的地位竄升,C#成了熱門的語言。報名C#課程,不只讓你學會簡單的網頁編寫,還能讓你更進一步製作出精美的個人專屬網頁!

mvno

mobile virtual network operators

freedompop

2G強調語音、3G強調網路應用,那麼邁入4G,就是流量數據為王的時代,這也給了像FreedomPop這樣的虛擬行動網路運營商(Mobile Virtual Network Operator,MVNO)更多的創新機會。

 
有些MVNO提供免費電話服務。

你只要購買他們的手機或是BYOD購買SIM卡開通,就能享受免費的電話與網路。

FreedomPop,因為他們有賣熱點機盒(Hot Spots)。它是一個小盒子,可以接收4G LTE網路,並分享WiFi給手機用,價格大約$200,每個月有500MB免費網路可以用,缺點是出門都要帶著這個小盒子。 

 Walmart自己經營的MVNO公司,營運風險也會比較低。

如果有額外的電話號碼,每個號碼還可以折$5,是我目前認為最穩定且經濟的T-Mobile MVNO方案。

You might get another Pop up asking for your password to complete the downgrade. Enter your account password and proceed. It will confirm once you are downgraded.

Note: The Basic Free Plan will say in the "Price: $0.00/Month" in the Top Box/Boxes after you have downgraded to Free.

https://www.freedompop.com/billing_settings.htm

You might get a pop up warning, just click yes or "downgrade anyways". This setting decides if you get charged for any Data Overages.

......

5$ Credit Require to Turn Auto Top-Up Off;

Freedompop changed this a few month back. It will ask you for a 5$ credit in-order to turn automatic top up off(required).

.....

The 5$ credit is to protect the account if you go over the allotted amount with Auto Top-up disabled. This rarely ever happens. You would need to be downloading a huge file right before you hit your limit, and in the 3 hour delay Sprint has when recording data used. They ask that you keep 5$ in credit at all times with Auto top up disabled, Make sure to re-activate your Credit every 30-90 days(see link)

https://support.freedompop.com/app/answers/detail/a_id/2233/kw/credit

Note: The 5$ Credit is refunded when it expires, If you notice in the link, it shows as "-$5.00" (credited).

You will be on the 100% Free, but you have to watch your data usage very carefully. With the overages turned off, when you get close to the allotted amount(100 mbs left), the account will suspend till you upgrade to a bigger plan, or you wait till the month rolls over to a new month. Currently there is no Pay As You Go Talk & Text.

The Basic Free Plans you can downgrade to- FreedomPop LTE/CDMA, Domestic LTE GSM & Global GSM HSPA+



(!!NEW!!) FreedomPop Domestic GSM LTE sim-The Free Plan is 200 text, 500 voice and 200 mbs Data.(
Use to say 200talk/200text/200data, but definitely 200talk/500text/200data
)

FreedomPop Branded Hotspots, and BYOD (LTE/CDMA Data) - The Free Plan is 500 mbs of 4G LTE, No 3G access.

FreedomPop Global GSM Phone Sim (HSPA+ Data)-The Free Plan is 500 Text, 200 Voice and 200 mbs Data.

FreedomPop added the option on the FreedomPop Global GSM Phone Sim to Add "WhatsApp Basic". That comes with 100 talk and Text and 200 mbs HSPA+ Data (Unlimited WhatsApp Roaming in 30 Countries). (To Add WhatsApp Basic, click HERE)

WARNING: There are No Confirmations after clicking the link above, it will switch you to the plan automatically. to read more about the WhatsApp plan, click HERE.

Note: CDMA plans, Domestic GSM and Global GSM plans are not compatible with each other. GSM Data is a little more pricey.


Free ("500 Mbs") added to your Free Plan with 10 x Freedom Friends(50 mbs per)




("IMPORTANT NOTE:") 500 mbs on the Free CDMA plan + 500 Mbs Free Each month with 10 Freedom Friends = 1000 mbs each month, 100% Free & (if you have generous Freedom Friends, they can also Gift you another 500 mbs total Maxed (combined Total) += 1500 mbs Free Each Month 100 Free No Charge!!!

("IMPORTANT NOTE:") 200 mbs on the Free GSM plan + 500 Mbs Free Each month with 10 Freedom Friends = 700 mbs each month, 100% Free & (if you have generous Freedom Friends, they can also Gift you another 500 mbs total Maxed (combined Total) += 1200 mbs Free Each Month 100 Free No Charge!!!


Here is a Great way to add another 500mbs to your account after you downgrade to the completely free account. Have you added your 10 freedom Friends? If you add 10 Freedom Friends, it will give you another 500mbs free a month, as long as the member stays active. 500mbs being the maximum. Freedompop has a FP Friends Group. Where other members go to learn about the extra data, and share email address just for Freedom Friends. See Link-

https://forums.freedompop.com/groups/

Scroll down to FP Friends and join the group. Figured this might help if you only get 200/500mbs* a month.

After you become a member of the Freedompop Group, you can add your email and add the email used here to your Friends list-

https://forums.freedompop.com/discussion/9898/post-your-account-email-addresses-here-updated-10-23-15/p1

If you send a request, they have to accept. If they send you a request you have to accept. Each person you add will give you 50mbs. Freedompop only allows 10 friends to count max. It is always good to add extra, just encase one cancels his account.

Some people are a little skeptical about doing this, but it is completely safe and nobody is allowed to email anybody else they add. They can lose their account if they take advantage. I have over 700 friends and In 2 years; I have never received on spam email. Because I have so many friends. I have had them gift me data out of the blue. You can gift up to 500mbs-(20mbs x 25 friends, 50mbs x 10 friends or 100mbs x 5 friends), they can also gift you the same. The max is another 500mbs.

Here is a post I wrote last year about gifting and the limitation>>>

https://forums.freedompop.com/discussion/5422/tips-tricks-of-the-freedom-friends-get-an-exrta-500-mb-a-month-the-limitation-of-gifting/p1

So you get a Guarantee of 200/500mbs* a month on top of your free 500mbs with Freedom Friends. It is possible your friends can gift you another 500mbs if you have generous friends.

Note: 200/500mbs*- 200 mbs is the Free Basic plan GSM Data, and 500 mbs is CDMA Data.

Note: Unfortunately, I don't run the "FreedomPop Friends" Group. Sometimes you will have to wait a few days to be approved.


Question about a Charges you got, after you downgraded



If you are being charged and you have already downgrade to the Free Plan, please check "Downgrade your Service Plans(Value Added)-" above. I have found, when a member gets charged after they downgrade, the (VAS) plans are sometimes missed.

On Occasion, you will also find charges, that are unrelated to the VAS plans. Normally those charges will be related to Overages, after you go over your allotted Data Plan and If you have Auto Top-up enabled. Check your account for the charge. Make sure you are logged onto your Freedompop account and click this link-

http://www.freedompop.com/billing_overview.htm

Or Open your FreedomPop account. On the Tabs at the top you will see"HOME--MY ACCOUNT--BILLING--EARN FREE--SHARE DATA--SUPPORT" Click "BILLING", and you will see a drop down Menu. Click "BILLING OVERVIEW".

This take you to the Billing Overview Page. Scroll down to Recent Transactions, and the Billing Tab. You will see a breakdown of all charges related to your account. You will find the Charge, and the Description of where the charge came from.

If the charge has no description, check the Data usage.

http://www.freedompop.com/acct_usage.htm?tab=dataTab#tabs

Or Open your FreedomPop account. On the Tabs at the top you will see"HOME--MY ACCOUNT--BILLING--EARN FREE--SHARE DATA--SUPPORT" Click "MY ACCOUNT", and you will see a drop down Menu. Click "USAGE".

This takes you to the Usage page. Scroll down to My Usage Details and click the Data Tab. Here you should find the Date, Time, Source & Data used. Great way to compare usage. If you noticed you have used more than your allotted plan, it maybe a charge for using to much data. You would have to compare Usage to Allotted Data for the month.

If you Notice a charge of $1.99 followed by a suspended account, take a peek at the $5.00 Credit, and see if this has also been used up. If you are one of the few that used your data past the 100 mbs threshold, and the 5$ credit"average 250 mbs" on Auto Top Up Disabled, these are overages. This happens when a user, uses up all of that data, in the 3 hour delay, FreedomPop has on Recording Data. This is a very rare occurrence, but it does happen. User downloaded a huge file, or updates right around the threshold, or maybe decides to watch a HD/SD video. This is even more common for the users without the 5$ credit. Overages always show as $1.99. Take a peek at your Data usage when you notice this charge.(Very Rare).

If find that the charges, do not match data usage, Service plans, or the charge has no explanation. Please contact Customer support here-

https://support.freedompop.com/app/ask

You can also contact them through Facebook, Twitter or Here on the FreedomPop forum("New Discussion" and than "Ask a Question").

薛定谔猫

薛定谔猫是关于量子理论的一个思想实验。

实验内容:
  这只猫十分可怜,它被封在一个密室里,密室里有食物有毒药。毒药瓶上有一个锤子,锤子由一个电子开关控制,电子开关由放射性原子控制。如果原子核衰变,则放出α粒子,触动电子开关,锤子落下,砸碎毒药瓶,释放出里面的氰化物气体,猫必死无疑。这个残忍的装置由薛定谔所设计,所以此猫便叫做薛定谔的猫。
