## Positive ShockHosting.net Review | Web Hosting Talk

This is my 4 month review of Shock Hosting.
I plan on reviewing again at the 1 year mark and then every year after that. I have a 3 year hosting plan that I pre-paid for.

I have multiple websites hosted with their Low Shock and Super Shock plans. Right now, they are very small websites. I have a landing page for my privately owned e-mail, a resume website, and a credit card deals website (think of SlickDeals, but for credit card bonuses.) The plan was to get the credit card bonus website going, but life got in the way. My work is going through a re-org, I’m applying for new jobs, trying to get a promotion, etc. I will pick back up in the fall. Anyway, on to the review!

Initial Signup Process:

I see Shock Hosting advertised in the WHT Shared Hosting Offers section all the time. They are pinned at the top, but I never really considered them. Why? They don’t get talked about much. Seriously! It was hard to find reviews. There are some out there, but not a ton like other web hosting companies. They also only have a 7 day refund policy which screamed “horrible host” in my opinion. I figured the servers would be oversold, because of their cheap prices (which includes a free dedicated IP) and the small window refund policy. I initially only planned on signing up for Shock Hosting as a quick trial (1 day) and then cancelling. I wanted to see what their servers were like and check out their resources, etc.

Shock Hosting sent a follow up e-mail at 3:00am on a weekday about an hour after I submitted the request to cancel. They wanted to ask a question about the reason I had put in my cancellation request. I said it was because my current host had more resources, which is what I was looking for as I build up my credit card bonus website. I am a night owl and I happened to be up at 3:00am! I responded to Shock Hosting, and we actually ended up working something out to get me to stay. I’ve never had a host do this with me before! I was totally impressed! I’ve only ever known hosts to let you signup for whatever you see on their website.

Support:

They’ve always responded pretty quick. I think the longest response time may have been up to 1 hour. Not bad at all. Most responses were around 30 minutes or so. I’ve only opened two tickets, but everything has been great so far. All tickets were opened in the evening, so it’s nice to get support outside 9-5 hours.

Servers:

WOW! Shock Hosting’s servers are some of the BEST I’ve ever seen in shared hosting. I am hosted in their Dallas location. 32 cores, with a server load always 3.5 or below. Often times in the 1.0 – 2.5 range. Everything is extremely fast. I couldn’t be happier! The only shared hosting company I looked into that I think has faster CPUs was MechanicWeb. I did consider them, but they cost more than what I’m paying with Shock Hosting. Plus, I’m completely happy with Shock right now.

Uptime:

I’ve had 0 downtime in 4 months. I monitor my websites with StatusCake. Shock Hosting did have some downtime in their other data centers. I received status update e-mails, and they were on top of their game to keep their customers updated. It was due to a switch that failed to restart after it crashed. Another time was in their Los Angeles datacenter and there was an issue with their upstream. Everything was resolved within a reasonable amount of time.

Final Thoughts:

They provide a free dedicated IP address with every hosting account. We’ve all heard that old wives tale that a dedicated IP helps with SEO. I’ve read countless articles that it does help and doesn’t help. All I have to say is that having the dedicated IP can’t hurt! I love having a dedicated IP with my shared hosting. Most hosts don’t even offer it, because of the shortage.

Shock Hosting is literally my new favorite host! I couldn’t be happier Everything has gone great, and support has been fantastic with my couple of tickets!

In the past year, I’ve tried: Hawk Host, BigScoots, HostWithLove, HostMantis, and CrocWeb. All these hosts are great (except for Hawk Host. Their servers are so slow and outdated.)

I won’t talk about each host, but if I had to rank them overall in order I would do:
1. Shock Hosting/BigScoots (tied) because BigScoots has the BEST support, but costs more.
2. 3-way tie between HostWithLove/HostMantis/CrocWeb. You can’t go wrong with any of these guys.
3. Hawk Host in last place.

I’ve been a WHT member since 2005. I’ve tried nearly all the big hosts mentioned here on WHT over the years. Shock Hosting deserves this glowing positive review for having fantastic servers, good prices, and extra perks! For those that want to verify the validity of this review, one of my hosted domains is: Inbox(d0t)GQ <—- that is the landing page for my e-mail domain. One of my other domains is: MyB@nkB0nus(dot)com <— credit card bonus website.

## ❓ASK – Do you think technology has more negative effect than positive ones? | NewProxyLists

Technology has done harm as much as good. No doubt, it has helped in the advancement of the world in various sectors like healthcare, education, business and many more. But it has also created as much problems which unemployment is at top. It has brought about addictions which robs many of proper living. The good technology has brought is as much as bad.

## reference request – Is there a distribution f(z) that returns non-zero if and only if z is a positive integer

I am looking for distribution $$f(z)$$ with $$zinmathbb{C}$$ that is non-zero only when z is a positive integer, namely:
$$f(z)=left{begin{array}{c} 0& znotinmathbb{N}\ text{non-zero}& zinmathbb{N} end{array}right. .$$
Does such distribution exist? If so, could you give me some examples?

## linear algebra – Why is the probability of a false positive not 0 for Freivald’s Algorithm?

Freivald’s algorithm (see the wiki) is a randomized algorithm for verifying whether the product of two $$n times n$$-matrices $$A$$ and $$B$$ yields a given matrix $$C$$ (i.e. $$AB = C$$). The way this task is accomplished is to introduce a random vector $$vec{v} in mathbb{R}^{n}$$ and evaluate whether
$$A(Bv) = Cv$$
The claim is that if $$AB neq C$$, then $$AB v = Cv$$ with probability at most $$1/2$$, and they provide a justification. Their argument for why 1/2 works makes some sense to me. What I don’t understand is why this bound can’t be improved further by the following argument:

Claim: Suppose that $$AB neq C$$. Then for almost all choices of $$v$$ (i.e. with probability $$1$$), $$AB v neq Cv$$.

Proof of Claim: Note that $$AB v = Cv$$ if and only if $$(AB-C)v =0$$. Let $$D = AB-C$$. Then $$ABv = Cv$$ if and only if $$v in ker(D)$$. Since $$AB neq C$$, $$D$$ is not the $$0$$-matrix meaning that $$dim(ker(D)) < n$$. Hence, $$ker(D)$$ is a proper linear subspace of $$mathbb{R}^{n}$$ and therefore has measure $$0$$. Thus, for almost all choices of $$v$$, $$D v neq 0$$ meaning that $$ABv neq Cv$$ with probability $$1$$.

Q.E.D.

Hence, if $$AB v = Cv$$, then $$AB = C$$ with probability $$1$$. Shouldn’t this mean that the probability of failure in Freivald’s algorithm is $$0$$ instead of $$2^{-k}$$?

Thanks.

## For what fields \$k\$ and positive integers \$m ge n\$ there are \$m\$ vectors in \$k^n\$ such that any \$n\$ of them are linearly independent?

This question arose in my answer for another question. Any help would be appreciated.

## diagonalization – Prove that a positive Markov matrix has exactly one eigenvalue with a value of 1

## linear algebra – Positive Definite implies entries of diagonal matrix are positive.

I wish to show that if $$A$$ is a diagonal matrix and is positive definite then it follows that the diagonal entries of $$A$$ are positive.

I am currently stuck in my attempted proof shown below:

Since $$Ainmathbb{R}^{ntimes n}$$ is positive definite, then not only is $$A$$ invertible, but $$det(A)>0$$, since $$A$$ is diagonal then :
$$det(A)=prod_{i=1}^{n}a_{i,i}>0$$

I am stuck here because the product of all entries of $$A$$ need not imply each one of them are positive. Therefore, how can this be fixed? I would also be happy if there is an alternative.

One thing I would note is that if we let $$thetainmathbb{R}^{n}$$, then $$theta^{T}Atheta>0$$ can be observed to be an element-wise matrix operation where for instance, each $$i^{th}$$ element of $$theta$$ is multiplied with each element $$a_{i,i}$$ in $$A$$.

## spectral theory – Is there a relationship between the spectra of minor matrices and the spectrum of a positive definite matrix?

Let $$G$$ be a Gramian matrix with full rank. In the question below, I will relate the eigenvalues of this matrix to results in a physical experiment, as $$G$$ will be an “observable”. If this sounds strange to you, forget about it, it is just a small point of view. Now to each such Gramian matrix I can form the minor matrices and my question is, if there is a relationship, like the Lapliacain determinant theorem, between the spectrum of $$G$$ and the spectra of its minors.

## functional equations – Varying sin(x) interval to cope only with positive values same as a range from 0 to pi

What I’m trying to achieve here is, given a range of values 0 – n, make it equivalent to sin(pi), that means (in Python code).

``````import numpy as np
import math

x = np.arange(0, np.pi, 0.1)
y = math.sin(x)
``````

This gives me only the positive values of the sin function. What if I want to vary that `(0 to pi)` range to anything, let’s say `(0 to 100000)` and have the same effect and tend to increate up to its middle-sector and decrease from that point onwards?

What I’m trying to achieve is a sin(x) modulation through a random range of integer values.

## Find positive integer \$n\$ such that \$4n+3\$ divide \$T_{n+1}(2)\$

Let $$T_{n}(x)$$ be the Chebychev polynomial of the first kind defined for all integers $$x$$. I came across the following problem which I have no idea to solve:

Find all positive integers $$n$$ verifying the property: $$4n+3$$ divide $$T_{n+1}(2)$$
