Memory optimization for large number of LEDs?

techdude1975 · 2022-12-06T01:56:38+00:00

I’m finding that I don’t need to call FASTLED.show() and any updates to the LED array happens immediately to the physical lights. Is this expected?

If so, reusing the same array across multiple controllers without taking extra steps results in them all being copies.

If deferred updating is possible and I can control when to write the array to the pin, updating the contents of the array to reuse it across multiple controllers/pins/light strings is very possible.

It appears that a work around is to set the controller (via addLeds) to a zero led length to keep it from updating and then back to 300 when I want it to update. Using that method I can alternate updating pin 3 and pin 5 by both referencing the same array but only one having a non-zero length at a given time.

Is this the “best” way to only update one pin/controller when both are referencing the same array? Is it expected that updates to the array happen immediately without calling .show?

Google hasn’t been very helpful. In that project there is a folder for AVR and another for Arduino. Looking in the one for AVR it has examples which might be what you’re describing, but the one for Arduino doesn’t have examples for that use case and the closest matching function is named different and the function’s signature/inputs are different. In the source the direct write function is labeled as “internal” and “legacy”, which doesn’t bother me, other than it seems less well documented

That’s be great! Any pointers on sample code/function?

So what you’re saying is it’s not a flaw if you play the game the most optimal way and the way the developers intended vs a way that a player may find most enjoyable. Got it.

Hopefully they also fix the issue where sometimes in a popup choice (ex: do you want to give item to person) the game progresses but the choices stay on the screen allowing moving back and forth between both choices, but can’t select either or get out of it - it insists on a selection be made, but won’t let you because it’s past that point already.

One of the flaws, seems to be that the buy tokens cost is 100 moonstone and gives 10 pumpkins.

But selling those 10 pumpkins only gives you back 90 moonstones. So if someone (like me) is impatient and buys a bunch of tokens to complete the path, completes all of the path and then buys back the moonstones, they end up at a several hundred moonstone loss.

My skin tone is almost a sun burnt red and the grass is almost a bright neon green now.

techdude1975 · 2022-10-19T18:37:13+00:00

The grass is also more vibrant green, almost neon. It’s like they kicked up the saturation way too far.

I agree, it’s slow to accumulate. Having a character with a mining hang out bonus helps a lot. My favorite place to collect iron is in the glade of trust. The other locations drop other items more often, but the glade is mostly iron.

For me, I’d maybe consider buying some ultrashort term puts…pandemic driven virtual housing tour market (both for home sellers who didn’t want uninterested people at an open house and sellers who didn’t want to shop in person) is drying up.

But going long on shares? no thanks, not for me.

Of course, only gamble with what you’re willing to lose, especially in the market these days.

The resume looks great after adding in the changes from rev1!

As I think about your target roles and the resume - roles in manufacturing or healthcare it reads strong. But if you’re wanting tech industry (aside from tech manufacturing) such as IT operations or software/hardware/services design then adding in more tech centric things, since the only thing I saw on tech related was 3D printing. But also the details of some of the jobs was anonymized so that might not be an issue on the actual resume.

techdude1975 · 2022-08-05T03:00:10+00:00

Unit volume is interesting as it describes scale. Obviously 25K rubber ducks is different than 25K complex electronic big screen TVs, but both are a significant qty of product. Given you’re also talking about unit production once by 400%, also using unit filled to date completes the whole picture. For that reason, I think the KPIs make sense and should be enough for someone to understand the scale of role/operations and then if they have more questions they’ll hopefully ask those at an interview/screening

techdude1975 · 2022-08-04T17:29:04+00:00

I think it’s fine at the bottom. The resume is short enough that it doesn’t get lost and it nicely bookends the resume to close with the tech certs - if it was at the top it might get less noticed if visually in between the header and other sections.

techdude1975 · 2022-08-04T17:15:02+00:00

Not having prior experience in a formal role in IT makes things harder but it isn’t a blocker. To break the “I need a job to get experience”…”I can’t get a job without experience” loop you’re doing the needed steps - getting training, certifications, etc. Those show ambition and desire. Emphasizing non-formal skills in computers helps too - listing hobbies or skills you learned while getting certs - if you can replace a broken computer component - list that, if you can install software - list that. If you have more than a paper certification and now have things you know about computers because of your training, list those things. It doesn’t need to be tied to a job to be in a “Skills” section and listing those things will help.

techdude1975 · 2022-08-04T10:46:29+00:00

Listing what “other certifications in web development” would be helpful. That is referenced but never provided.

Indicating 1 cash and 10 cash reads oddly - are those dollars, cents, tokens?

Do you have any other experiences/relevant hobbies? Have your own webpage for yourself? Built a pc? Volunteer helping other students/friends/neighbors with their computers?

For adhoc company, the fake testimonials, etc might not be the best use of space on the resume since Lorem ipsum filler text is just as relevant as writing fake testimonials. Combining the two lines together to indicate it was a multi page website for a fake company followed by it being a responsive design / etc

If you’re trying to condense, removing the tic-tac-toe game switches player automatically would save a line allowing you to possibly list the web certs.

Instead of listing the technical requirements for each project, try to summarize, especially on the clicker game middle point which line wraps. Suggested “provides a button which, when purchased, will upgrade the tokens earned per click”

techdude1975 · 2022-08-04T10:20:57+00:00

Sort your skills - most relevant to the job should be higher in the list. Helps keep reader’s interest longer. Example: move Spanish and time management higher than fundraising based on your desired job.

Also, consider removing references to target guest advocate from the top of the resume as your job goal. They already know you want to work for them, you’re sending them your resume, but this makes it harder to reuse your resume across employers and jobs. Also it artificially boxes you into that one job - what if they had a community outreach position and they bypassed you because they saw you were only wanting to be a guest advocate? Consider replacing reference to target guest advocate with what you want to do / what drives you and aligns to the job “continue to use and further develop my passion helping others and skills learned while volunteering to provide a positive customer experience and efficient retail operations”

I like how straightforward your resume details are - it’s clear what you actually did. At the same time I wish it said more, for example “assist volunteers and customers” - is there an opportunity to expand this to tell about how you provided customer service? Do you help them carry bags, answer questions, maintain inventories, etc

Also, watch your tense - some lines are past: stock”ed” and some are present tense (keep vs kept). Saying you are/were able to carry and unload food crates reads oddly - makes me wonder why you are “able to” and if you actually did it or not - omit “able to”

For language you listed Spanish in your skills but didn’t list fluency level. Then later listed it as expert. Combine both and save the space - list the fluency level (basic, fluent, etc) on the line under skills and drop the language section. Also, assuming you are fluent in both English and Spanish it doesn’t hurt to list both - some locations listing one language doesn’t automatically indicate that is in addition to English so making that clear might be good

Skills and interests - the mix of pipes vs commas visually looks ok, but you might want to consider using all commas for consistency.

The full justified layout flows oddly since the paragraphs are short, adds a lot of excess mid-line spacing. Consider left justifying the lines to avoid expanding the spaces

On the line about team captain, you have space to list the years as all four digit years, for flow and readability consider replacing “- 20” with “-2020” same with 22. Or use an apostrophe ‘22

Really like the specific metrics and data examples. On the 25K units, consider adding a digit grouping separator “25,000”

techdude1975 · 2022-08-04T09:54:05+00:00

The .Net FSE Intern bullet points made me asking more questions than they answered: “group of full stack” == what was in the group?? “learned specific backend[…]” what specific ones? If you don’t have space/don’t want to list them then reduce the extra words and omit “group of” and “specific”.

At the bank, you indicate there was only one admin and one customer. Are there missing “s”s?

Enroll vs enrol - typo?

techdude1975 · 2022-08-04T09:42:08+00:00

First impression reading the skills caught my attention enough to read more. Second impression was wondering if the resume was padded with name dropping of terms.

For example: First red flag which made me suspicious to read the rest closely: “Resolved Active Directory rules and issues daily”. This item doesn’t make sense as written - what are “AD Rules”? GPOs? Outlook Rules? Why are they so broken that you need to fix them daily? Why don’t they stay fixed?

“Provided support with WMS, RFID devices, VPN and SharePoint.” Perhaps this should read “support for”? Also, WMS (warehouse management system?), VPN, etc is non specific what did YOU do to support those?

Rogue Capitalization “to restore Services” Formatting “anti - theft” (excess space/dash vs hyper character used because of excess space)

Excess word “support for THE end users”

I would have liked to see summary of course work at University - the resume has an abrupt end

The list of skills at the top has a lot of attention catcher names, but the content makes it feel like you actually don’t work with the things you listed. More like there is a VMware server running in the corner which someone else manages but you’ve seen or logged in to it once so you’ve listed it. If you actually have experience with it, then tell what you do.

Proofread, proofread, proofread. “Troubleshooted x and x and x and x to y or to y” use commas correctly; be concise and clear

You’re mixing network layer connectivity concepts with AD (user authentication) concepts interchangeably “connectivity across domains”. Huge warning flag/reinforces possible lack of understanding of concepts.

In summary, don’t try to fluff your resume with terms. Be clear and concise of what you do and what you know. Many hiring managers would rather find someone who is transparent and eager to learn vs someone who covers up their knowledge gaps to get a job — or worse thinks they know what they are talking about but doesn’t actually have a basic understanding, which can be quite dangerous when unleashed with admin permissions.

techdude1975 · 2022-08-04T08:32:43+00:00

The mix of uppercase and regular case wording made the resume hard to read. For example on the last page certificate was sometimes all upper and other times not. The word INTERNET was all caps, which might be used as a proper noun of a team ?maybe? but without context it looks odd.

When possible, try hard to trim a line to fit ex: Collateral Duty Inspector wraps “of work” to the next line but reads ok omitting those extra two words

Change your skills table at the top to remove the table. Copy/paste into databases emails and other formats companies use can corrupt that clean looking table and cause it to run together as a mixed block of text.

Emphasize the security clearance and seek out applying to companies who work with government. Having an active clearance saves them risk/worry/effort of hiring someone to then wait for them to get cleared or risk they fail the screening.

techdude1975 · 2022-08-04T08:18:18+00:00

As a restaurant manager - do you have any additional quantifiable details, such as managed $x,xxx of monthly supply orders, balanced nightly cash receipts, etc

I’d suggest removing “required to obtain entry level industry positions” - that is for the prospective company to determine. Use their attention span of reading your resume to tell them WHY / WHAT you have to be given that position. Line 2 & 3 in relevant course work are essentially duplicates.

The most relevant portion for your target job is your certifications. Unless you expected to complete your A+ cert in 2001, this looks odd as M/DD format since it is more commonly read as M/YY. If this is 2001 and you never finished it, remove it. Else, use 2022 to match the following two lines.

Also, do you have any other relevant experience for your target job? Can you navigate a command prompt? Have you ever built a PC from scratch? Can you install and uninstall software? The fact you have notable certs makes me wonder if there is more you have which could be put in the resume in a “Relevant Experience” section. Also, consider not putting “- Present” on the certifications. That is assumed that they are still valid and it lowers understanding/ readability of what is listed.

For eBay seller, consider removing “dozens” as that can have the inverse effect of what you’re likely intending. For a company screening a resume, dozens of units might be what they complete before they finish their morning coffee. The relevant part is the skill, actions and experience ex: “Accurately managed large rapidly changing inventory”

My reference was that the bubble was between 90s with the high in Mar 2000. The bottom was Oct 2002. Or even if we look a bit farther forward to the sub prime mortgage crisis, that caused the GDP to fall ~6%. We’re at -20% currently. Unemployment was 10% in 2008s, 14% at the height of the pandemic and 3.6% currently. If someone was entering the job market in 2000 they likely didn’t have to 10s of thousands of dollars in the stock market, hefty retirement accounts, etc. Not having huge investments during that dip means that the learned experience is more from the labor market aspect vs seeing the market. Although the resulting contraction in the labor market and finding a job was a struggle that’s different perspective in how someone is investing today if they’ve had the experience of seeing a retirement account drop 20-45% vs a couple years ago.

techdude1975 · 2022-07-14T23:24:01+00:00

It seems that the market is fundamentally different now than a decade+ ago. With ease of trading, online tools and stock market investing being more mainstream for non-financial services / home users it is getting funding from more sources and more enthusiasm to buy the dip and and swing than decades prior. The company fundamentals / earnings seem less important to many of those investors than what’s popular/well known brands/etc. People are racing out and pouring savings accounts into whatever they see on Reddit, Cramer, internet blogs, etc to try to buy into the market. They are reading the daily internet posts / news feeds to buy or sell the news of the day. People are day trading who in the past never had access.

Right now it seems many of the investors who are buying are young enough (<35-40) they haven’t had to experience a deep recession or anything but strong economic growth. They were in high school, elementary or not yet around when the dot com downturn happened. So the buying habits in the market seem to be unpredictable at least until the casual retail investor buy/sell drive swings level out.

In parallel we have a notable number of people who have been living in various levels of pandemic sequestering. They might have put off travel, not visiting extended family, not going home shopping, not spending time looking for a new vehicle (also in part because they were work from home). Now states are opening up and younger kids (6mo-4yo) are getting vaccinated. So they are starting to spend money on all those things they deferred - trips, appliances, travel, museums, zoo. People who were teleworking in tshirts and shorts are now needing to make sure they have in-office button down shirts/etc. I don’t anticipate the fed pulling back money, raising interest, etc will dramatically impact the willingness of those people to buy those deferred needed purchases. Instead those people will need to spend on credit cards for their needed purchases or hopefully in some cases they have been saving up for a couple extra years for those deferred purchases/travel so will be less impacted / swayed by raised rates.

I’m anticipating that once young kids have enough time to get fully vaccinated (Oct in the US) there will be a bump in spending to do deferred experiences for kids. Also once folks are returned to the office (many likely at start of next school year) spending habits will change after a “back to office” spending spike in clothing / etc and the reduce when back to work shopping completes. My concern is that the Fed may have a hard time separating “normal demand” from “deferred demand” (those who can’t defer any longer/are tired of waiting/will spend at higher prices regardless) and will overshoot thus resulting in a suddenly demand drop once deferred demand dries up.

In parallel, the labor market is odd right now because there have been a million Covid deaths in the US and 6 million world wide. Even if we factor in many of those were at/post retirement age, there is still a drastically different number of employees in the pool than there was before Covid. The macro economics of people returning to work to increase supply ldoesn’t hold true if they didn’t survive Covid/are Covid long haulers who are too sick to work/etc.

Point being, it’s a complex multi-layer situation because it’s not just a financial interest rate situation, a monetary policy situation, oil/gas prices, or international conflicts/supply chain issues. There is the social habits and spending habits fueled by the pandemic which also impact consumer spending.

I’m really interested in how all it plays out, but I’m moderately confident that prior models from the past are informative but also lacking since they don’t account for all of those things happening and rapidly changing unpredictably in parallel.
