去年同城 300 块钱收了套松下家庭影院，总共 6 个箱子+DVD 碟机。缺点是功放和低音炮集成在一起，没法用除自带碟机以外的设备输入音频，于是当做 CD 机和收音机用了

一直喝的飞鹤星飞帆，现在孩子快三周岁了，有时自己还会找奶粉喝。翻了下购物记录 900g*6 罐的三段奶粉买了 10 箱多一点。断母乳又不怎么会吃辅食的一段时间喝的最凶，一周就能喝光一罐

上月给老爸买的 Vivo X100S 16G + 512G 反馈不错，他比较喜欢拍照。PDD 到手 3200 ，生产日期 2024 年 11 月安全下车

@y051313 丢弃不至于，但你得自己去本地邮局翻，邮局不会派送或电话提醒

@nanlan1995 不知道。卡是 7 月 3 号激活的，就当月用过几次，不知道什么时候被封的，连个邮件通知都没有。app 里也看不到封禁提示，不过已经不能进行充值等操作了。你要是能正常充值就说明卡片状态没问题

@jhytxy 客服没有给出具体封号原因，信用卡地址只是猜测:

Hi Iop,

Dylan from the giffgaff team here today, I understand that you're having some issues with your account as you're not able to receive texts or top up

I'll be happy to investigate this for you.

I've had a look at your account and I can see that there has been a permanent ban on the account. I'm afraid that you have breached our terms as outlined in the Terms and Condition's Section 3.5 Part J. For this we have had to suspend and ban your SIM card.

As your usage is not in line with our Terms & Conditions, this has resulted in a final bar being placed on your account, which I'm afraid is permanent. At giffgaff we want all our members to enjoy our services in the best way possible within the rules set. Overusing any of our services impacts the network and destroys the service experience for all other members.

We do have a responsibility to our members to ensure this is not the case and the network is used fairly, which is why it is clearly stated in our Terms & Conditions how your SIM card can be used:

I appreciate this may have been unexpected but you can see our terms and conditions and why we had to take the steps to permanently bar your account:

Please click the "fair usage" button at the top and scroll to Section 3.5 Part J.

Kind regards,

Dylan, The giffgaff team

@huishu 这个月末才到 180 天，不是超期问题

@randychoi 最近几天想给卡片续期才开漫游，之前一直关闭状态。另外 app 里显示余额还有 14.99 磅，应该没有偷跑流量

读了一些数学书，打算把还给老师的知识再拿回来~没读完的明年继续：

1. The Calculus Lifesaver （ by Adrian Banner ） 除了附录都读完了。整本书深入浅出，作者对极限理解极为深刻。
2. Statistical Inference (by George Casella) 读到第二章就读不下去了。前置知识储备不足，解不出类似 \(\int _{0}^{\infty }e^{-x^{2}}~dx\) 这样的积分，需要多重积分技术。
3. Calculus Early Transcendentals 9th Edition Metric Edition by James Stewart, Daniel Clegg, Saleem Watson ，为了补足 Multiple Integrals 内容找来看的，目前只看了一点点。
4. Linear Algebra and Its Applications, Global Edition, 6ed （ by David C.Lay ）。线性代数，读了一部分。
5. Discrete Mathematics and Its Applications (by Kenneth H. Rosen)。翻了翻第一章命题逻辑。其他书里多少会涉及命题逻辑，不过不如专门教材讲得具体。
