Below see two kernel density estimations. What could you say about them? Most likely, you say that the first plot is based on a uniform distribution, and the second one is based on a multimodal distribution with four modes. Although this is not obvious from the plots, both density plots are based on the same sample: 21.370, 19.435, 20.363, 20.632, 20.404, 19.893, 21.511, 19.905, 22.018, 19.93, 31.304, 32.286, 28.611,....

Those who ever owned an old Nokia phone like 3310 or 3210 might still remember its wonderful ability to compose your own ringtones straight on the phone’s keyboard. By arranging notes and pauses you could end up with a popular tune beeped out of the phone’s speaker, and furthermore, you could share it with your friends! If you missed that era, here’s how it looked like: Unimpressed? Well, trust me, it was really cool back then especially if..

Monero has always found innovative ways to solve difficult privacy problems. Nowhere is this exemplified more than in the case of Monero's subaddress technology.

Hashtable Hashtable 实现了 Map 接口，用于存储键值对， 禁止 null 元素 。 用作键的对象必须保证hashCode与equals的可用性。 Hashtable 是 线程安全 的，但一般来说，如果不需要考虑线程安全问题可以使用 HashMap 作为替代，如果需要线程安全的高并发哈希表可以使用 ConcurrentHashMap ，总的来说就是，一般不需要使用 HashTable。 Hashtable 具有两个性能相关的参数： 初始容量( initial capacity ) 和 负载因子( load factor ) ， 容量是指 HashTable 桶（ buckets ） 的容量，初始容量即 HashTable 在创建时桶的默认大小。在哈希冲突的情况下，每个桶会通过 链表 存储多条数据。 负载因子默认是 0.75 ，一般来说该值是最佳值。 当 HashTable 容量超出负载因子时将会进行 rehash 操作，该....

Return on Data: When governments fail to make surveillance useful

There is this common refrain about how companies have data about you and could do bad things. Yet governments often pass surveillance laws that are much worse, and by definition, you can’t “vote with your wallet” for them. So in a world where I’m already giving data to third parties, it is useful to ask what I get in return. If we are talking about corporations, we get ads! Yes, but we also get:

When the pandemic hit earlier this year, schools around the globe quickly embraced online teaching to continue their curriculum. While online teaching wasn’t entirely new in this space, it certainly wasn’t the norm. This meant that many teachers had to adapt quickly, as these 2 funny videos illustrate: https://www.youtube.com/watch?v=CCe5PaeAeew https://www.youtube.com/watch?v=Zy_y9yOrgxk However, I’ve loved every part of this trans....

I get between 10 to 20 emails per day and, usually, more than half of them are phishing attempts. Phishing attempts are a type of email scam that typically aims to obtain personal data of the victim, including username and password for email accounts and popular services (Gmail, Hotmail, mail.ru, Twitter, Amazon, etc.), through pages forged ad hoc to simulate login sections. -Continue to read the article on SerHack.me

Circular gradients are commonly used in pie or doughnut charts to change the colour of segment as the angle around the center of the chart changes. In many non web platforms, the ability to generate these gradients is provided as part of the standard APIs. For example, Android provides a SweepGradient. In the browsers, only Linear and Radial gradients are provided. Thus, if we want to a circular gradient, we’ll need to create our own.

Been playing around with Swift Package Manager (SPM) . Creating a new Swift package (ie. project) is pretty simple. To create a library package, we can use the following: swift package init --type library Alternatively, to create a command-line utility use: swift package init --type executable Turns out, there are a few options: empty, library, executable, system-module, manifest. With a little elisp, we can write a completing fu....

In reply to Ed Hurst. Thanks brother and namesake! I appreciate your willingness to face my Spanish writing and I don't have any doubts about your good nature. But I am afraid that some English speakers might be put off; and, especially, many Spanish speakers could be put off or intimidated due to the massive English content. They are the ones who concern me the most..
