Ask HN: This is my MVP - would you pay $10/mo for my monitoring service?
Here is what I propose to offer. Would you be interested in this? It this space too crowded? Am I adding enough value/reducing enough cost?

For $10/mo

10 url checks - alarm on status codes, header regex, content regex, content size, response time (DNS* lookup, first byte, content download, or the whole thing), etc. I want this functionality to be the key differentiator. I will capture the full response (headers + html) on failed requests and store them for 90 days, so you can visualize them.

10 system checks - Any combination of Ping, DNS, SSL cert, TCP, UDP, SMTP, POP3, IMAP

All checks can be tested on the spot to ensure that they're set up correctly. (Will not be recorded as 'official' tests).

100 notification credits - will integrate with twilio to provide sms or voice alarms. 2 credits per mms notification and 5 credits per voice notification. Notifications via Twitter or Email are free/unlimited.

10 check executions per hour. (e.g. 6 minute interval)

System will only initially run out of a small number of US DC's, but if it takes on it will expand to worldwide testing nodes covering multiple backbones. (IOW, the MVP won't be very good at dealing with network reachability - something I've never found much value in with my own monitoring)

Interface will strive for extreme simplicity.

----------

Post-MVP:

Once I get some sense of my costs (how much hardware it takes to run say 1,000 customers or 10,000 urls on), I want to really kick up the offering on the url check. I want to move to full DOM simulation with click checks etc either via HTMLUnit, Selenium, WebKit, or something else. This will be a premium offering.

Android, iPhone, desktop integration.

Agent software so you can perform additional checks from a location of your choosing, on whatever interval you like. Likely be Java. Would it make sense to open source this? Would it be giving away too much? Maybe open sourced after we gain "significant" traction. Or maybe it would be developed openly, but not allowed to be used for commercial purposes or relicensed.

Two way API, custom checks.

Show HN: Penumbra, a perceptually optimized color palette based on natural light
https://github.com/nealmckee/penumbra
For this palette, I used recent advances in color science, which made perceptual design more accessible, to choose a set of colors (mainly for syntax highlighting) that have uniform luminance for less visually uneven, fluidly readable code, but at the same time maximally distinguishable hue and chroma. The background colors are based on natural (sun-)light and shade for a more pleasing look than equally neutral greys.

For much more detailed info, including the construction, check out the repository.

There’s also already a (bare-bones) VSCode extension, linked in the repository, but it could admittedly use more informed distribution of colors over tokens, language specific highlighting and perhaps more opinionated use in UI elements.

Where do you search for remote jobs?
Pretty much all of the typical job search engines are based upon searching for a position title/description and a location.

In the age of the internet one would think that second box would be less relevant, but sadly it seems still to be so.

Two schools of thought on how to gain early traction for consumer-focused startups

Show HN: Marple – Interactive time series visualization for engineers
https://www.marpledata.com/
Hi HN, excited to share the project I have been working on for the past two years.

Marple was created by engineers for engineers. Marple helps them organize and analyze their sensor data in a more user-friendly way.

We’ve all been there: measurement data from an experiment or test needs to be analyzed but the only thing you have is a few data files flying around. You do not have a clue how to open or read the data. So what you do next is open your Python/Matlab/Jupyter Notebook/… and start coding in order to make some sense of the data. We didn’t like that process, so we started Marple to solve this issue.

Engineers tend to log data at frequencies from 1Hz to 10kHz and usually log hundreds of sensors at the same time. Data sets usually contain millions of data points. In order to make our web-based data visualization responsive, we had some technical challenges to tackle. We developed our own visualization engine based on PostgreSQL that is able to visualize millions of data points pretty much instantly. This allows us to create an interactive visualization environment which is perfect for data exploration, even for large data sets!

This is the second time we show Marple to HackerNews, but since then we made some big steps. We made a pivot to a cloud product and now offer a free version of Marple. Feel free to head over to our website and give it a go. Let us know what you think of it!
MongDB on AWS (RDS-Style)
http://www.9apps.net/blog/2011/7/26/mongodb-on-aws-rds-style.html
MongoDB is drawing crowds, lately. Some even dare to call it the new MySQL. Together with Usabilla we built a 'choas monkey proof' MongoDB replica set on AWS.

We used AutoScaling and Route53 to build a replica set that we can grow and shrink on demand, by just launching or terminating instances. Our default set has 2 large primary/secondary members, and 2 arbiters.

Ask HN: What's the value of consulting experience?
Hey all,

I'm a current college senior dealing with an existential 'post college' dilemma. One form of this question is, "Does working at a good consulting firm teach you skills valuable for running your own startup?" or - does it teach you something worth more than what you would learn by trying and failing at something else?

In my estimation, the best way to learn is to actually do something, but the chance to get exposure across different companies and industries does have a certain appeal to it. This being said, I am obsessed with the opportunity cost of such an action, especially in terms of my ability to task on more risk now (debt notwithstanding).

I'm passionate about tech and have worked in different capacities within the industry to date from a business side. I do some web-based work for myself and continue to try to improve my coding abilities, but it's not my forte at the moment. Thus, I'm contemplating taking a consulting gig, killing my life with work, and trying to learn a lot in a year or so before poaching my CS friends from Google, Facebook, wherever they are and trying to get them to jump in the deep end with me.

Thoughts? I'm hesitant about taking such a 'path of least resistance,' but know that it's not quite as if I am selling away my soul forever. Curious for perspectives from the community here.
Ask HN: Is Google's 20% time a myth?
Suppose a person were considering joining Google and saw as one of the primary appeals the possibility of spending a decent amount of time on a blue sky project that he/she has already been working on, but which almost certainly has no short-term economic payoff. Are the social incentives set up at Google to make this possible?

I've gotten many conflicting reports about this from people at Google and in the industry generally. What seems to be the case is that the 20% time is really "120% time" -- i.e. you're welcome to spend your time working on your own projects but the expectation as far as output of an individual employee on their primary responsibilities isn't any less.

Does anyone have knowledge or personal experience on this topic?

Show HN: Mailwitness – Digital Signatures over Email
https://mailwitness.com
Hi HN,
I'm Marek Dopiera and I wanted to share the digital signature solution which I made with my software house. Your feedback would be much appreciated.

We've just launched it - it's a service for signing documents over e-mail - https://mailwitness.com. It still has some rough edges, but hopefully it is useful already.

To sign a PDF with somebody, you e-mail them the PDF and put sign@mailwitness.com in CC. If they agree, they need to forward it to sign@mailwitness.com. When they do, you all get your document signed. You can generate PDFs from e-mail, too for convenience.

We made this to raise the safety bar of agreements made via e-mail. Via anecdotal evidence, we know that if people do not use services like DocuSign or HelloSign, they consider an e-mail conversation as proof or they print, sign and scan documents. I think we're offering more safety and convenience, because we're preventing the documents from alteration, forging fakes and backdating (by using OpenTimestamp, which essentially constructs a Merkle tree and puts its root into a Bitcoin transaction).

I'm hoping that our service becomes useful also because it doesn't require any sign-up (just one confirmation e-mail for Ts&Cs), it's free (in the basic model) and doesn't require the extra cognitive load on learning a web app or a mobile app.

You may argue, that one can create a fake e-mail account and use that. That's a valid point, but the reality proves that verification via e-mail is enough for lots of people (vide the agreements over e-mail or DocuSign or HelloSign). In the future we may create paid options, which would include extra identity verification. Even without that extra option, things are not as bad, though: if you use your work e-mail, it's usually your employer who verified your identity.

Another question you might have is spoofing. If your e-mail has a valid DKIM signature (which is the case for most major e-mail providers), we'll accept your message. If it doesn't we'll send you a message to verify that you can also receive e-mail.

For data safety, we have designed the service such that we discard the documents as soon as we process an e-mail (usually a low number of seconds).

Finally, there is legal safety. We operate under the EU law, which qualifies us as a "Trust service provider" and puts requirements on our service. What we do, qualifies as an "Advanced Digital Signature" and according to the EU law, cannot be denied legal effect based on the grounds that it is digital.

Monetization path is unclear yet - I want to see if this catches on and if yes, how people are going to use it. Some options include extra services like using your own certificate rather than ours or identity verification.

I would really love to hear your feedback - especially for what reasons you would not use it.

Thank you

I and a friend (it was his idea) put together this site over the weekend, on a lark. It's admittedly purposeless, but we're hoping that people don't find it completely useless.
Critique our startup: HeavyInk.com
http://heavyink.com
Our team of 2.5 engineers (two real engineers, and one half business guy / half engineer) have spent the last three months coding up HeavyInk.com in Rails - it's a mashup of an Amazon.com style retailer for comic books (individual issues, graphic novels, subscriptions to issues, subscriptions to graphic novels - you name it), and Facebook style social networking (yeah, I know: "Oh, God, not ANOTHER social netowrking site..."), with some other goodies thrown in.

The comic book retailer space is a bit crowded, but after doing a bunch of research (see details elsewhere at news.ycombinator: http://news.ycombinator.com/item?id=75296), we concluded that the existing firms all failed in major ways.

There are some cool technologies under the hood (Coco/R for Ruby to parse out details on authors and artists from free-form human-readable text descriptions), and a lot of cool code reuse (Sanskrit, Beast, etc.).

So: please check out the site, and give your feedback, either here, or in the HeavyInk forums (http://heavyink.com/forum/forums/1 )

We really do take all feedback seriously, and have prioritized various features and bug fixes based on customer comments.

Thanks!

Show HN: A better Reddit search engine to find menswear recommendations
https://reddrecs.com
Hey HN Community!

We built this simple community search tool that basically allows people to search through thousands of past Reddit threads and tens of thousands of recommendations using tags. It mostly covers a few bigger subreddits like r/BIFL, r/MFA, r/AskMen, r/SkincareAddiction but along the way, I expanded it to include other smaller subreddits too. In addition to filtering by category, power users can also search by

-Body Fit (big thigh, long torso)

-Occupation (work in retail, teacher, doctor)

-Age (18-24, 25-35), Size (height, weight)

-Brand comparison (similar to: X)

-Use (suitable for wedding, everyday wear)

-Location (available in UK, use in Northeast US)

-Mood/Style (minimalist, vintage, retro)

Check it out. Buy fewer, buy better. Happy Earth Day!

Ask HN: What's Your Experience With Flippa?
I'd like to build a website, cultivate it a bit, and then ultimately sell it so I decided to poke around on www.flippa.com today to see what people were actually buying. For the fun of it, I sorted by price and was looking through some of the sites that sold for around $10K (USD) and I was shocked to see that:

- a lot of them didn't seem to be much more than a hastily thrown together Wordpress blog

- a lot of the sites claimed high Google page ranks but the only way I could find them was by
Googling their actual URL (They didn't specify the keywords they had high ranks for)

- a lot of them didn't even claim traffic numbers

What do you think is going on with that? Are there people out there that'll really buy a website no matter what and try to make it big? Have you ever bought or sold anything on Flippa? Any tips?

Thanks in advance HN!

Show HN: I made a macOS tool to prevent me from working late hours
https://burnoutbuddy.rockbruno.com/
Hey HN, I used to be the poster child "10x" engineer. I always went far beyond the job description, actively involving myself in everything and having no issue working late hours/weekends/vacations if necessary to achieve my goals. I did this because I love engineering and it brought me a lot of career success, but it wasn't until recently that I realized this was actively destroying my life and leading me to an early death. Putting work above my own life completely ruined my social life, and eventually made me so stressed and anxious that it became impossible for me to relax and do anything in my life besides working myself to death. Even work itself was damaging me as I was then spending every single day (including weekends) under overwhelming stress for being unable to not accumulate extra work and responsibilities I knew I should be rejecting.

I was in desperate need to stop being a workaholic, but I had zero self-control. I was so addicted that even though I knew I should lay back and relax, I would always end up checking Slack in the middle of night, get stressed, do some work I shouldn't be doing, and spend the entire weekend burned out. I needed my computer to actively stop me from doing so.

I initially solved this by using Apple's own Screen Time feature, but it doesn't really allow you to totally block an app. It only lets you limit how much you can use it on any given day, which was not sufficient to keep me in check as I truly needed the ability to completely disable certain apps at certain hours. Some third-party productivity apps do have this feature, but they're paid and not geared towards work addiction (quite the opposite, actually), so I didn't want to pay a subscription to something that didn't fit my use case.

I ended up developing my own solution. I made it for myself with zero commercial intentions, but I thought there might be others in this same situation who could benefit from it, so I decided to release it to the public as a free tool that tracks/requires no user info whatsoever. It improved my life and I hope it can be useful to someone else here too.

Show HN: Jig – Live coding your business dashboards (now with demo video)
https://www.jigdev.com
Hi again HN,

Last month I posted this Show HN [0], which was well received but most comments were by people asking for a demo / video / docs, because the install step was too much a barrier for entry. So here it is updated with video and (partial) documentation. I really wish I can get people's feedback on the tool itself.

About Jig:

Jig is a live coding environment to quickly create interactive business dashboards / small internal apps.

My target customers are growing startups who spend too much time in Excel/Google Sheets to create their growth reports / retention charts / ad hoc analyses, while they have the coding expertise to compute metrics with a proper programming language.

The language is Javascript, but you don't need to know any html/css/d3 for charts or tables, cause all that part's taken care of. Connecting to databases and or APIs is also straightforward, so all you need to write is code that transform your data in the way you want to present it.

It's meant to be light and nimble (no server / no database needed) and it runs on your computer.

Sorry for those who've seen this before, I won't repost soon.
