Project Nayuki

Poor feedback from readers

Running this website since year , I receive some email feedback regarding my articles from readers every month. About 20% of the conversations I get are shocking: They are absolutely horrible in the quality of the ideas and the writing, and they often demand personalized help without showing any skill or effort. (The other 80% of feedback are generally interesting and decent, and those examples are hosted on a separate page.)

As for the poor feedback, please don’t send me messages that look like the examples below! Read the text and judge for yourself. There exist needy, thankless people out there in the world.

Subject line: nayuki.io Fix Error

Hello nayuki.io;

Hope you are doing well.

I am a digital media expert representing a very successful Website design & SEO Company. I found your details from the internet and thought you might be attracted to getting a latest website designed.

I have prepared an extensive report, detailing some key issues that should be fixed for superior online visibility of your website.

I would like to give you an idea how we can help you to achieve this achievement.

I have a large specialized team who can fix the issues. I am assuring that you will see a radical change in your Google search ranking once these are fixed.

If this is something you are paying attention to then allow me to send you a Proposal.

Sincerely,
[RF]
-----------------------------------------------------------------------------
Note: - If you want to see the detailed plan, kindly reply back. We will contact you with details.

My commentary: My contact policy forbids SEO and promoting your company’s services. Additionally, you have a number of unprofessional grammatical errors – unnecessarily capitalizing {Website, Company, Proposal}, and lacking the word “of” in “give you an idea how we can help”.

Furthermore, “you might be attracted to getting a latest website designed” – I already have this website which I designed and works just fine; “detailing some key issues that should be fixed for superior online visibility of your website” – I’ve already done a lot of work in page optimization; “radical change in your Google search ranking once these are fixed” – this is a false inflated promise, and I assure you I am satisfied with my current search rankings.

Subject line: Need a guest post on your website

Hi, Admin We have visited your website.      https://www.nayuki.io/
I really like the way your website looks. We want to post on your website. Please tell me your guest post and link insertion price if you are interested tell me  the gambling post price without sponsored type. I am waiting for your reply. Thanks.

My commentary: He clearly didn’t read my contact policy, which explicitly says that I refuse guest posts. He is sending from a Gmail address, and on the surface the message doesn’t look like a mass-automated spam blast.

[Attachment: high traffic site (1).xlsx]

My commentary: An unprofessional message with multiple grammatical errors coming from a Gmail address. I wouldn’t hire you for SEO even if it was a service I wanted (which I don’t). The “I am waiting” phrase suggests you’re from a certain part of the world. You clearly failed to read my contact policy against SEO, guest posting, and marketing.

Hi!

I have come across your site, and strongly feel that your website is a perfect match for us.

I am a content writer and trying to create awareness regarding chemistry among people worldwide. You will rank higher on search engines with my content.

How about starting collaboration and making a collective effort?

We are looking forward to hearing from you soon

I was initially planning to write a post for your site but since you've declined my offer, I think it will be great for our audience if you added these links as reference.

My commentary: After her first email, I replied with a quote of the “No marketing, commercial solicitations” section of my contact policy. She ignored what I said and doubled down on promoting herself. Is she stupid or malicious? Also, the content she proposed has nothing to do with chemistry (contradicting her initial email), and anyway why would someone provide free articles for my website? They’re just trying to gain incoming links for themselves.

Hello,

My name is [P]. I am currently looking for websites where I can promote our casino/betting page and many more sections by an article or blog post. Do you do this type of advertisement on your site? If you can share your media kit that would be great.

If this is something that you do – please send me your offer. Looking forward to hearing from you.

from Research Group from NUDT

Subject line: A Survey about Your Method Implementation Practice

Dear developer,

Thanks for your attention! This is our Software Engineering research group from National University of Defense Technology. Method is the basic unit in Object-Oriented programming and implementing methods is a common activity in software development. To facilitate software development automation, we hope to understand your practice about implementing methods. We totally list six questions and any comment is welcomed. We believe it will take no more than three minutes to finish these questions. Thanks again for your participation! 

Our online survey is in Google Form. Here is the link: https://forms.gle/[...]. 

Best regards,
[S]

My commentary: I don’t know how you bulk-harvested my email address, but I specifically forbid survey solicitations. Worse, you forged your from-address so I cannot respond to you, and your organization is clearly associated with the Chinese army which is known to be controlled by an oppressive government. And you contacted me a second time 12 days later. Get lost, you spam scumbag!

from [JH]

Subject line: Hey

I'm probably way out of line here but I really like your site and I wonder if you'd ever consider selling it? 

I work for [Company] and I'm almost certain our buyers would be interested in this, you'd likely do quite well.  

Please feel free to let me know if you'd like to discuss and I'll send you through some info. If not, no problem and all the best.

Thanks,

from [JA]

Subject line: Help with a page update?

Hi there,

I’m [J] with [Company]. I came across your page and saw you referenced Wikipedia for the definition of Efficient Market Hypothesis (EMH). I wanted to share our definition page for Efficient Market Hypothesis (EMH) which wasn’t crowdsourced like Wikipedia is. Ours was written by an expert writer, edited by seasoned in-house editors and then vetted and reviewed by a 2nd expert on our financial review board that has deep subject matter expertise in the area. You can find it here: 

Efficient Market Hypothesis (EMH)

Our definitions simplify complex financial information so that our readers have the confidence to manage every aspect of their financial lives. I hope that the page might serve as an alternative to the Wikipedia page!

If you’re curious about other pages or content please let me know, thanks, and I look forward to speaking!

My commentary: Another shit-tier marketer NPC, exhibiting these critical flaws in judgement:

  • You grabbed my email address and messaged me in violation of my contact policy, which specifically forbids both link exchange and promoting your company.

  • Your subject line is a complete lie; I never asked for such help and your information is not helpful.

  • Your email contains two tracking links, which is creepy and I refuse to click them. The third link is not a tracking link, but it’s unclickable because it begins with “www.” instead of “https://www.”.

  • When searching “efficient market hypothesis” on Google, your company’s web page already holds the top result. So why do you feel the need to spam me to get more incoming links to your site?

  • While you might think it’s fun to disparage a chaotic community effort to contrast with your perfect expert-created walled garden, history is not on your side. Wikipedia has already beaten Encyclopædia Britannica and Microsoft Encarta and Google Knol, and I am confident that they will outlive your company in the long run.

We had a few [topic] questions about whether [topic] is better, so we recently finished off an article explaining the differences and which is better.
thought i'd let you know as we cover it pretty well, almost a little nerdy in detail, but hey... that's us.

If you get a chance, i'd love to get some feedback and if you think it's useful, it would be greatly
appreciated if you wanted to mention/link it on your site.
probably on your page https://www.nayuki.io/page/what-are-binary-and-text-files or a different page if you think it's more useful sharing there?

Anyway, appreciate you having a look.

My commentary: He failed to abide by my contact policy where I explicitly prohibit marketing solicitations, link exchange, and promoting one’s company/service/product. Also, the quality of writing his email message is suspiciously much below the writing quality on his website. And finally, I suspect the reason he emailed me and mentioned that page of mine is because my page has one keyword (JPEG) in common with the article he is trying to promote.

Subject line: Re: Hey Nayuki Have you heard [company]?

Hey Nayuki,

I hope you’re having a good day. I haven't received a reply to the email I sent a few days ago so I just want to do a quick follow up with you.

It's perfectly fine if you decide not to link [company] in the article, but would love some feedback if you have any? This will help me reach out to you with more relevant information in the future.

I look forward to hearing from you shortly.

Kind Regards,

[JK]

My commentary: After his first pushy, aggressive commercial solicitation, I ignored the message, hoping he would understand it as a signal that he was unwanted. He did not see it that way, and sent this second message to try to grab my attention again. Disgusting behavior.

Subject line: Hey Nayuki Have you heard [company]?

Hi Nayuki,

My name is [JKE] and I'm part of the team behind [company].

I recently came across your page https://www.nayuki.io/page/so-you-want-to-be-a-day-trader-bad-idea and noticed that you have included some trading resources. In that regard, I am sure that you would like to mention [phrase] or [phrase] as well.

In case you haven't heard of us, [company] is a trusted platform where you get the freedom to learn to become [aspiration] without risking real money. We have thousands of people who already using [company]. which I believe would be super useful for your readers.

Please feel free to share any of our links on your site to encourage traders to easily find a [tool]. I hope you like what you see and once again, we’d love the opportunity to be included on your website.

Thank you for your time and I look forward to your reply!

i would be waiting for your reply

- [R]

My commentary: You can keep on waiting, because free help won’t be offered. This is the same guy who contacted me on and . The linked page isn’t my post on GitHub; someone copied text from my web page and posted it on their account. As for your request, your spelling is sloppy, but more importantly you severely underestimate the complexity of implementing a “simple requirement” to modify a QR Code generator and scanner to be incompatible with the existing standard.

Hello

My name is [S], and I'm a content manager at [company].

I’m reaching out because I came across nayuki.io and as I see you take on advertisers. So I'm interested in purchasing some space for a sponsored article on your site.

My commentary: GTFO. You either missed or completely ignored my email contact policy. It says: “No marketing, solicitations. I will not accept commercial requests such as: Guest posting, link exchange”. The reason this policy exists is because my website represents my own authentic voice and personal guarantee of quality, not a mishmash of authors who have their own ulterior motives.

Subject line: want to generate a different Image than a QR code.

i want to generate a different image than a qr code. so that the data inside the qr code could not get reviled. and the organization software could only scan it. not any other qr code scanner. is it possible to do some changes in your source code and obtain the objective.

or you may provide me with an a bit simpler way to do so. it would be very much helpful.

My commentary: He posted a GitHub issue, so he probably didn’t have a chance to read the email contact policy on my website. Once again, there is a neverending stream of needy people who demonstrate no effort or skill. His poorly worded message seems to demand consulting advice and custom work while offering nothing.

i what to generate a different type of image (like qr code but certainly not qr code) which can't be scanner from other devices (like normal qr code scanner), it can only be scanner using the organization's scanner .. (like snap code in snap chat). i just need some information ..because i am new in image processing...it would be a great help!! .. you can contact me on facebook.. (https://www.facebook.com/[sr])

Hi nayuki.io team,

My commentary: This is your third-time emailing me after I told you to stop (first time was 2018-08-17).

You have been added to the global spam blacklist database, TYVM.

Thank you.

Best regards,

My commentary: When I look at where to spend my time on, I can choose to write articles and code for a public audience, helping hundreds of people who read it over the months and years. Or I can choose to answer individual private questions like yours, helping only one person on one specific problem. Guess which one is a better use of my time? This is why as a rule, I do not help people individually – unless they bring something to the table, like pointing out a flaw in my published work (thus helping me improve) or offering payment for my time and attention.

Hi Nayuki,

I won’t glorify your pathetic and useless response by thanking you. It seems like you have assumed an air of snobbery in order to hide your shitty code. If it’s enjoyment you seek, I suggest sticking to masturbating by watching your mom take a piss through the hole that you made in the wall.

Subject line: A programming problem

Hello again. How do you think, what would be the most efficient solution to this problem:

Let's say there is a bit field, call it flags. The goal is to fill flags from the position zero up to a desired position, which is specified by a flag, e.g. 1<<4. As a result a binary sequence 10000 would become 11111. My current solution (in Java) is:

for (int i=0; i < (int)(log(flag)/log(2)); i++) { flags |= 1<<i; }

Maybe there is a more efficient or traditional approach I am not aware of?

My commentary: First, we do not have a prior conversation. Second, your question is not about my published work but is regarding your personal problem which you need help with. Third, if I spend time to answer I would not benefit in any manner, hence I require payment for this type of request.

Let me make it abundantly clear: I am not a free service for solving your problems. If you want free advice, ask on Stack Overflow.

My commentary: This person doesn’t show effort in the content of the message.

My commentary: Doesn’t demonstrate effort in solving his own problem, and has poor English grammar. Does not seem to understand that although my software is distributed free of charge, for me to give you any kind of one-on-one private service, especially for the sake of your business development, requires payment for the privilege of helping you. Not the worst feedback, but not great either.

Subject line: Advertising offer

Hello.

Our company would like to cooperate with you. Could you please tell us, is your site available for guest or sponsored posting? Or maybe some another article advertising? We are owners of some sites in tech niche and we would like to post an article with a permanent do-follow link on your site. If you are interested in our proposal, please, tell us your working conditions and prices.

Thank you for your time, we waiting for your answer.

With best regards
[KS].

My commentary: While I’m not against advertisement offers, this message has numerous red flags. There are two grammar mistakes, “some another” and “we waiting”. The “waiting for your answer” reminds me of unprofessional messages examples at the bottom of this page. The sender gives no contact or company info. And finally, the sender’s domain name has zero search results on Google, which is suspicious and doesn’t seem like a legitimate company.

Subject line: Regarding Logics

Yeah, so.......    I have never done this before.   I found you and your site after doing a very specific search on Google about a month back....   you were one of three results.   The search yielded one of your scripts/codes in which there was a reference to your site and contact information.  The search was for a highly specific number, your code was related...... everything appears to be in resonance.  Long and short, I would love to have a coffee with you and discuss some things you would most likely be interested in given your site and related articles.  The universe keeps pushing me to reach out and it is being unrelenting.  So, here I am.  I live in [city], NY......   I have a boat on the river in [city] and frequent Kingston/Ontario often.  I would be interested in sailing in to Toronto or making the drive for a meeting.  I have a suspicion of universe’s intentions and I believe it to be for me to share some of my research, data, etc. with you or perhaps I am mistaken and it is for me to learn something from you;  I have followed some of your work during the course of mine and believe we have pertinent discussion points.  Either way, I will gladly exchange fiat to facilitate this meeting (after all, I read once that money is something you give to strangers for favors).  ;-) 

I hope this all doesn’t sound too crazy and that you may be interested in this conversation.  My schedule is a bit tight atm however, I am looking to get the ball rolling and to schedule something in the upcoming weeks/months.

Sincerely,

I have not written an assembly language version of tea-test.c. Why are you looking for such a file?

The assembly code is for the speed-critical computations. The tester performs minimal work, and works fine in C.

Thank you for your understanding.

My commentary: Your initial request doesn’t make sense, you’re asking me for code that I haven’t written or published, and your wording is very sloppy. Also, the fact that you linked to a file in my GitHub mirror of web-published code (which I consider a secondary source) suggests that you might not have thoroughly read my official web page (whose URL is included in the source code). As a rule of thumb, the more desperately you plead for help, the less likely I am to grant you my charity.

My commentary: You spammed me with a second copy of the message a half hour later. So, where is your code? Where is the effort you spent on analyzing my code and comparing with yours? You can’t just ask for free advice without bringing anything to the table. Also, your spelling/wording shows a lack of attention to detail.

Anyways, I am stuck on how I can best program my code so it is simple to use but also easy to create. I was wondering if I could look at your source code for some ideas. Also, if you have some suggestions for me that would be great. By the way, my program is a Gui and I have include some images of what it looks like.

Thank you very much for your time.

Sincerely,
BH.

Subject line: Solution to the Project Euler 444

Hi Nayuki,

I was looking out for the java solution to the project euler problem 444, The Round table lottery. But that is not listed on your site.

Do you know the solution, if possible can you send it me.

My commentary: I publish code and articles for my sake, not for yours. I choose to publish what I want, when I want. Where is your gratitude when you’re making such a request to me?

What I actually wrote to him: It is not listed on the site because I have not solved it. Please don’t ask for things that don’t exist. I’m unhappy to receive your request.

And “Please show with examples”? How dare you address me like I’m your private tutor!

What I actually wrote to him: I’m sorry I cannot answer your request, because I don’t give tutorials on basic operations. You should be able to find the answer in the instruction manual.

Subject line: Arithmetic Coding Code enquiry

Hi
i am miss AP from India.I have downloaded the Code for arithmetic coding (java) written and posted by you.  I am trying to run this program in JC Creator.We are able to build the file without any error but we are not able to get which file to run , to give the neccessary input for the program.

Kindly help me for running the program in any way possible.Kindly tell us which file is supposed to be run for providing the input and the file from which we have to see the output.If possible provide the steps for running in any platform or software which you might have used.

Awating for your reply.

Thanking you in anticipation

Yours truly
AP

My commentary: This request is similar to many others on this page, but at least it was worded relatively politely. But if you have trouble finding the main() method even after I documented the software package on the web page, then I have a right to doubt your competence and wonder if you’ll continue to ask more basic questions. Also, what’s up with people from India saying things like “awaiting/waiting (for) your reply”? It feels like I’m being rushed, and we never say that phrase around here in Canada.

Hello Nayuki ,
I have taken help from your site " http://nayuki.eigenstate.org/page/project-euler-solutions " while solving project euler problems
I have solved 50 questions from project euler and found that not every question contain pdf for further reading(accessed after solving the question)
it seems you have solved many questions in project euler.
it would be very nice if you help me by giving me the list of question which contain pdf after solving....because i think that the question that contain pdf are actually important and i want to do all those......
Thanks

i found your site, and i was wondering if it is possible to store the letters. i know how to store numbers in letters, but i want to know if u can store letters/formulas in a letter... if u know what i mean...
lets say (a-b)^2 = (a-b)(a-b)
or if thats not possible, maybe just (a-b)(a-b) or anything like that stored into letter A ??

thank you

My commentary: No, I don’t know what you mean, and I don’t follow what your newfangled interpretation of math is.

Subject line: Question on Automatic Caesar cipher breaker ?

Hello my friend,
I'm looking for your Automatic Caesar cipher breaker. It's very useful tutorial to be honest with you  but I don't understand very much the idea how to break the cipher text ?
What I understand is :     1. I need to calculate the number of times for each letter
2. then I need to compare with letter frequency on english language
3. after that ... What I need to do ? and how can I get the key ?

My commentary: I find it very presumptuous that you call me your friend on first contact. Also, I have explicitly stated on my about page (version as of Apr 2012) that I do not give basic tutorials on math or programming.

Hello,

I have recently visited your site to view how others had solved the "Dwite Computing Competition" problems. As i am a beginner at Java, i was unable to understand how you had solved the problems, although, i am very much interested in finding out. If it is not too much of a bother, i would greatly appreciate if you could send me things such as tutorials which you find would help me to learn Java. I am not completely new at coding, and i know the basics but i haven't gotten the logic and many of the functions of Java yet.

Thank you,

My commentary: Your poor spelling shows a lack of respect for my time. I must conclude that you don’t deserve any attention from me.

Notes

The quoted messages are largely unmodified. Only these modifications were made:

  • The name of the person was abbreviated (e.g. John Smith into JS), to protect their dignity or what remains thereof.
  • Some hard line breaks were removed for better readability.

Other than that, nothing else was changed. In particular, the spelling, grammar, punctuation, and spacing are exactly the way the person wrote them.

I noticed that being addressed as “sir” is strongly correlated with the sender being from India. I conjecture that it might be taught as a respectful form of addressing someone, but I personally find it to be very cold and distancing. That being said, I am not inviting you to feign familiarity with me either.

Don’t get the misimpression that all my emails from readers are bad, though. The majority of the feedback has been good, ranging from compliments to academic research to relevant ideas to business deals. I’ve only highlighted the bad ones here to illustrate a minor burden that comes from being an author on the web.
